The latest project updates

Transmission Gully opening – ‘Heads up’ regarding traffic patterns

I’m sure you will have heard the good news that Waka Kotahi has directed the Transmission Gully contractor to open the new motorway to traffic by the end of this month. This is great news and something the region has been looking forward to. It will have the positive impact of bringing more visitors to our city and local businesses. It will also mean changes to traffic volumes in key areas - particularly on Kenepuru Drive.

This is likely to be even more so in the early days as people flock to the area, curious to try out the new road.

At council our priority is the needs of our city, residents and businesses. We’ll be monitoring how the changes may impact our local roading network and working closely with Waka Kotahi if anything does need to be addressed.

We do expect the volume of traffic on the section of Kenepuru Drive between Raiha Street and the Kenepuru Drive/ Transmission Gully Road roundabout to increase by approximately 30 per cent. The changes we have already made in this area are intended to keep traffic moving safely and reliably.

Council and Waka Kotahi will be monitoring traffic flows and will use those results, along with feedback from businesses and road users, to assist our decision-making if any further steps need to be taken.

If you have any feedback please give us a call on 04 237 5089 or by e-mailing enquiries@poriruacity.govt.nz

It’s going to be an interesting time as we all adjust to the new systems. I’m sure you are all look forward to getting onto Transmission Gully to check out the result of these many years of mahi. Just as you will be interested to see the new road, so will many other people, so please be patient while people experience the road and get used to the changes. We expect it will take a period of weeks for traffic to settle into predictable patterns.

The new motorway is going to provide enormous benefits for our city and region. We know that local people and businesses may have questions or concerns as everyone gets used to the changes – please be assured that we are looking out for your interests.

Pine tree removal plans

Work to remove two large pine trees on Kenepuru Drive, above the Transmission Gully intersection, is planned for this weekend (11/12 December).

The worked is due to carried out between 7.30am and 5pm Saturday and 9am and 4.30pm Sunday (conditions permitting), with a single lane operating under stop/go traffic management.

It is crucial the trees are removed as they are on an unstable bank, and the work needs to be done before the opening of Transmission Gully to avoid potential disruption to larger traffic volumes.

We will do our best to minimise any disruption but anticipate there will be some delays. Thanks for your ongoing patience.


Kia ora – we’d like to update you on work on the northern Kenepuru area projects and on the Ambulance Drive roundabout.

Ambulance Drive roundabout

The Ambulance Drive roundabout will ease access for motorists trying to turn right out of the businesses on the eastern side of Kenepuru Drive. When Transmission Gully opens, the traffic along Kenepuru Drive from the Transmission Gully link road roundabout to Raiha Street is expected to increase by up to 50 per cent at busy times, exacerbating the existing issues.

The roundabout will give motorists on the eastern side of Kenepuru Drive the option of turning left and undertaking a u-turn at the roundabout.

Work completed so far

The Ambulance Drive roundabout is now fully constructed and the temporary pavement widening has been removed.

Kerb and channel and excavation work for the new footpath areas has been completed. We’ve also finished the streetlight ducting, cabling and associated connections.

We know there have been some issues around traffic congestion lately. To reduce these impacts some activities are now being completed at night.

Work currently underway

Work currently underway includes:

  • Completion of the western side (tactiles, footpaths and topsoiling)
  • Installing two raised pedestrian crossing platforms and associated drains (please note this will involve weekend work to minimise disruption to businesses)

Completion

All going well with the weather and Covid-19 alert levels we plan to complete all work on Ambulance Drive roundabout in November.

We apologise for any inconvenience during this work and ask you to please drive carefully through the area.

For any queries related to the work, call Downer on 04 562 6566 or our contact centre on (04) 237 5089.

More information on Ambulance Drive roundabout is available on our website here.

Design work for the northern Kenepuru area projects

Following a tender process, we have appointed WSP and Local for professional design services on the northern Kenepuru area projects. We look forward to working with them as they develop detailed designs for:

  • Lower Main Drive to Ferry Place footpath
  • Lyttelton Ave/Walton Leigh intersection upgrade
  • Lower Main Drive to Te Ara Tawa shared path
  • Lower Main Drive/Kenepuru Drive/Lyttelton Ave intersection upgrades

Design work will start in early November 2021 and is expected to be completed by March/April 2022. Once completed we will review our construction schedule and update you on the roll out of construction work.

Please note: Short-term improvements for Titahi Bay roundabout were originally part of this project however, these have now been incorporated into plans for a full upgrade to the roundabout following completion of the current northern Kenepuru projects.

Construction of a new accessway on Lower Main Drive

Early next year we plan to start work on creating a new accessway on Lower Main Drive for Bishop Viard College, the Seventh-Day Adventist Church and Te Ngkau Tāpu Parish. We are also constructing a new car park for the Seventh-Day Adventist Church.

This work is needed so that the existing accessways on Kenepuru Drive can be closed to enable upgrades to the Kenepuru Drive intersections with Lower Main Drive and Lyttelton Ave.

We are planning to tender for the accessway work in November and award the contract by late January 2022. All going well construction on the accessway (and the Seventh-Day Adventist car park) will start early next year and be completed by mid-2022. This work is required to be completed before construction of the new Kenepuru Drive intersections at Lower Main Drive begins.

You can read more about all the Kenepuru corridor projects here.


Kenepuru Station Access

The access to Kenepuru Station has been transformed, with improved lighting, resurfacing, vegetation improvements around Porirua Stream, removal of trip hazards and the installation of art work. You might like to check it out sometime. Greater Wellington Regional Council are also planning to put in ‘Train Replacement’ LED signs at the Kenepuru Drive entrance to the station by the end June 2021.

Kenepuru Drive/ Raiha Roundabout

Monitoring of the recently completed roundabout including considering stakeholder feedback is being done in two stages: Stage 1 - prior to Transmission Gully opening, Stage 2 – after Transmission Gully opens. The Stage 1 monitoring is underway and initial results have highlighted that some changes are required. The proposed changes will be confirmed and put in place before the end of June 2021, after analysis of traffic surveys from February 2021 and post construction safety audit recommendations due in March 2021.

Kenepuru Station to Bluff Road

Shared Path The contract to construct the Shared Path has been awarded to Downer with construction scheduled to begin this month.

Kenepuru Corridor Package 1 – Construction Tender

Tenders for the construction of physical works at several sites (Main Rd/ Wall Pl int; Raiha St/ Prosser St int; Raiha St/ Broken Hill Rd int and a cycle crossing point on Kenepuru Drive) will close on 12 March 2021 with construction scheduled to begin in April.

Kenepuru Drive/ Ambulance Drive intersection upgrade

On 15 December 2020 an information meeting was held, focusing on plans to install a roundabout at the intersection of Kenepuru Drive and Ambulance Drive. The roundabout will give motorists on the eastern side of Kenepuru Drive – who have difficulty turning right during busy periods towards the Kenepuru Dr/ TG Link Road roundabout – the option of turning left and undertaking a u-turn at the roundabout. The upgrade will also improve pedestrian access across Kenepuru Drive, including a zebra crossing.

The design of the roundabout has commenced and incorporates feedback from the information evening.

Kenepuru Drive culvert

As a reminder the Kenepuru Drive Culvert immediately north of Ambulance Drive was reassessed in 2018 and 2019 concluding that the culvert is capable of carrying HN-HO-72 and HPMV traffic loading without restriction.

Kenepuru Drive/ Transmission Gully Link Road

Nightworks are underway on Kenepuru Drive in preparation for the construction of a new two-lane roundabout, part of the Transmission Gully project’s Kenepuru Interchange. Once Transmission Gully opens, Kenepuru Link Road will take traffic to and from the new motorway and connect with Kenepuru Drive at the new roundabout, located near North City 10-Pin. We will maintain two lanes of traffic flow through the worksite on Kenepuru Drive during peak times.

Please be aware that traffic will be under ‘stop/go’ traffic management at times during the night. Bluff Road will need to close for 6-7 weeks from the end of April, with no right turns in and out during the staging of works. No access is available by Lower Main Drive. A diversion will be available from Raiha Street and Hospital Drive Parking will also be removed in front of ESR, the Institute of Environmental Science and Research. The footpath on the western side will still be available to pedestrians, but it will be a congested work site, so caution is advised. Work is scheduled for completion in September.

We will keep you updated as works progress. Please contact 0800 TGINFO (0800 844636) or info@tg.co.nz for any questions.

Variable Message Signs

In preparation for the opening of Transmission Gully, electronic signs have been installed on Kenepuru Drive on the approach to the Kenepuru Drive/ Transmission Gully Link Road roundabout. When the Transmission Gully Link Road opens, the signs will display key destinations and the estimated time it takes to reach them. Travel information is updated regularly as traffic conditions change.

Feedback

We would appreciate any feedback via kenepurucorridor@pcc.govt.nz


Kenepuru Corridor plan - overview

A number of transport studies have been carried out in the Kenepuru area to work out what improvements are needed to make it easier and safer for vehicles, pedestrians and cyclists to safely access businesses, Kenepuru Landing, Summerset Retirement Village and the city centre, as well as handle the increase in traffic following from Transmission Gully (SH1).

Download the latest plan to fine out what’s been achieved, what’s underway and what’s planned.


Kenepuru Drive/Raiha Street roundabout project

We are monitoring this temporary roundabout, which was completed in March 2021; this includes feedback from users and how it responds following the opening of Transmission Gully.

The key requirements of the project is to:

  • Address the intersection delays, especially for those turning right from Raiha Street
  • Cater for pedestrians and cyclists by keeping through speeds to below 30 km/h, in line with safe system principles
  • Enable u-turns by 12m long single unit trucks
  • Cater for over dimension vehicles and large trucks.

As there are a number of uncertainties, including the impact of Transmission Gully, we decided to install a temporary roundabout before Transmission Gully opens to allow for it to be tested by road users and modified as needed. It will be made permanent in due course.


Kenepuru Drive/Ambulance Drive roundabout project

This roundabout was completed in November 2021 and provides a safe turning and crossing point for motorists, pedestrians and cyclists.

Motorists on the eastern side of Kenepuru Drive, who have difficulty turning right during busy periods, are now finding it easier to turn left and undertake a u-turn at the roundabout.

The reduced speed created by the roundabout has also meant it is safer for pedestrians and cyclists to cross Kenepuru Drive. We look forward to doing the finishing touches to the street lighting soon.

As with all our projects we will continue monitoring along Kenepuru Drive to look at speeds, volumes and delays to make sure things are working well.


Kenepuru Railway Station to Bluff Road shared pathway and crossing

This project was completed in two stages in late 2021 to construct a shared pathway in front of ESR between Bluff Road and Kenepuru Railway Station.

Work on the first stage, between the entrance to ESR and Ambulance Drive, began in April 2021.

While the shared path is being built there will be less parking available on the street in front of ESR, as we will have temporary traffic management measures in place to enable the construction to be completed safely and efficiently.

The second stage, between the entrance to ESR and Bluff Road, was completed in late 2021 following completion of the Transmission Gully roundabout and intersection with Kenepuru Drive.

Following completion of the shared path, permanent parking restrictions are likely to be put in place in front of ESR to increase visibility and make it safer for pedestrians using the crossing point south of Bluff Road. The extent of these restrictions will be confirmed once details become available.


Kenepuru Railway Station accessway improvements

The access to Kenepuru Station has been transformed, with improved lighting, resurfacing, vegetation improvements around Porirua Stream, removal of trip hazards and the installation of art work. You might like to check it out sometime.

Greater Wellington Regional Council are also planning to put in ‘Train Replacement’ LED signs at the Kenepuru Drive entrance to the station by the end June 2021.


Kenepuru Corridor intersection improvements

Construction of these intersection improvements was completed in 2021 to manage the extra traffic volumes expected following the opening of Transmission Gully:

  • Raiha Street/ Broken Hill Road: to reduce the wide conflict area and the risk for all road users. (June 2021) View the plan
  • Raiha Street/ Prosser Street: construction of a mountable roundabout to reduce speeds and near misses between vehicles. (May 2021) View the plan
  • Main Road/ Wall Place: widen the intersection to reduce the delays for exiting traffic. (June 2021) View the plan


Kenepuru Drive cycle crossing point

Construction was completed in 2021 to create a cycle crossing point (approximately 100m south of Flooring Xtra) to provide a safe crossing point for north bound cyclists on Kenepuru Drive to access the Porirua Stream Pathway. View the plan.


Northern Kenepuru area improvements

Northern Kenepuru area improvements

We’re working together to make improvements to the northern Kenepuru area. These improvements will make it easier and safer for vehicles, pedestrians and cyclists to safely access businesses, Kenepuru Landing, Summerset Retirement Village, Bishop Viard College and the city centre. These improvements will also help us to manage the traffic growth anticipated from the Kenepuru Landing development and the opening of Transmission Gully.

Design work is underway and is expected to be completed by late 2022. Once completed we will review our construction schedule and update you on the roll out of construction work.

Read on to learn more about the Northern Kenepuru Corridor projects.

Construction of a new accessway on Lower Main Drive

Work is due to start in mid-March on construction of a new accessway on Lower Main Drive for Bishop Viard College, the Seventh-day Adventist Church and Te Ngākau Tapu Parish (weather dependent). We are also constructing a new car park for the Seventh-day Adventist Church as part of this work.

All going well, construction is expected to be completed by August 2022 (subject to weather and Covid disruption).

This work is needed so that the existing accessways for Bishop Viard College and Seventh-day Adventist Church on Kenepuru Drive can be closed to enable upgrades to the Kenepuru Drive intersections with Lower Main Drive and Lyttelton Ave (currently planned for 2023).

Work on the Lower Main Drive accessway will happen in two key stages:

  • The temporary access for the college and churches will be constructed at the top of Lower Main Drive to ensure access is maintained throughout the entire construction period and until the permanent access off Lower Main Drive is constructed and operative.
  • The second stage of work will create the permanent new accessway on Lower Main Drive just up from the intersection with Kenepuru Drive. There will be some traffic control measures in place during this phase – more details to follow.

Downer is our contractor and work will take place Monday to Friday from 7am to 5pm, however, there may also be occasional weekend work.

The key projects

We are planning to install traffic signals at both intersections and provide crossing facilities to make it easier and safer for pedestrians, and cyclists to get to and from the city centre. It will also be safer for all road users as there have been a number of crashes and near misses in the area, and once completed, public transport will be rerouted from Kenepuru Drive through Kenepuru Landing.

Construction of the new accessway on Lower Main Drive is part of this project.

Why we are proposing these changes

Both intersections are currently very busy, with 28 reported crashes and near misses, within a 100m radius, over the past 10 years. Side roads are also experiencing significant delays with conflicting turning movements in and out of these side roads. When Transmission Gully opens, changes in traffic patterns will add more pressure to this area. The proposed changes to these intersections will make it safer for all road users and also enable traffic to flow smoothly on Kenepuru Drive

Significant growth at Kenepuru Landing and the probable increase of Bishop Viard College doubling its roll will result in more people walking and cycling. This is going to put increasing demand on existing crossing points. This growth, combined with Transmission Gully opening, will cause additional delays for motorists and safety concerns for those using this crossing.

Development of Kenepuru Landing and Summerset means the Lower Main Drive/Kenepuru Drive intersection needs upgrading to provide safe access to residents. These improvements will also give residents of Kenepuru Landing an alternative access to Bluff Road and Hospital Drive.

Currently, public transport is unable to safely service the Kenepuru Landing/Summerset area. These improvements will enable public transport to service the newly developed Kenepuru Landing and Summerset Retirement home area.

Designs for this work is planned for completion in early 2022.  Construction is planned for completion in mid-2023.

View the plan below


The city centre revitalisation plan identified that there is a lack of easy and attractive pedestrian access between Kenepuru Landing and the city centre.

The most accessible route is from Lower Main Drive, across Kenepuru Drive and along Lyttelton Ave to Ferry Place and enter Te Manawa, the heart of the city centre. Currently the intersection isn’t easy for pedestrians to navigate their way across.

To improve this route for people walking we’re looking at modifying the intersection and providing safer pedestrian crossing points as well as upgrading the footpath.

View the plans below


We are constructing a shared path that runs from the Kenepuru Drive/Lyttelton Ave/Lower Main Drive intersection down Lyttelton Ave and Station Road to Te Ara Tawa. This will enable residents from Kenepuru Landing to safely access Te Ara Tawa and Porirua Railway Station from Lower Main Drive.


Next steps

Detailed design of the northern Kenepuru area projects is planned for completion by late 2022 (subject to Covid restrictions). These projects are:

  • Kenepuru Drive new intersections with Lyttelton Ave and Lower Main Drive
  • Lower Main Drive to Ferry Place footpath and the Lyttelton Ave/Walton Leigh Ave intersection upgrade
  • Lower Main Drive to Te Ara Tawa shared path

Construction of the Kenepuru Drive intersections with Lyttelton Ave and Lower Main Drive is currently planned to finish in late 2023. The timing of the construction of the other projects will be advised once the programme is confirmed.

Titahi Bay roundabout upgrade

As a result of ongoing growth, residential development and the Infrastructure Acceleration Funding agreement, we are looking at a permanent solution for Titahi Bay roundabout. We are currently scoping the project and will keep you posted. Read more about the funding and the residential growth expected at Kenepuru Landing.

FAQs

19,000 to 20,000 vehicles per day based on a mid-week survey at two locations in April 2018.


Yes, modelling predicts that traffic volumes will decrease slightly on the northern section of Kenepuru Drive, and will increase by approximately 4000 vehicles per day (20% increase) on the southern section of Kenepuru Drive.


Yes. This traffic will be over and above the increases from the opening of Transmission Gully.


Yes, traffic surveys have been scheduled annually, from April 2019 at the same locations as the 2018 baseline surveys, and at a number of other locations including Prosser and Raiha Streets.


Yes, it is expected that average speeds will not change significantly on the northern section of Kenepuru Drive, and reduce slightly on the southern section of Kenepuru Drive below the current average speeds of around 40 km/h between 8am and 6pm. 


This manoeuvre will become more challenging with increased traffic volumes. Future concept designs will take this into account.


Kenepuru Drive has not been identified as one of the nation’s high risk urban corridors. Increased traffic will have a potential impact, so safety is a key consideration in all design solutions. 

There have been 36 reported crashes including one fatal and eight minor injury crashes along Kenepuru Drive, excluding Titahi Bay Road roundabout, in the period 2014 to 18. 

The majority of the crashes have happened on the southern section of Kenepuru Drive.


Yes, all transport modes are being considered which is why we have adopted a corridor approach that includes the Te Ara Tawa shared path. 

Our newly developed Growth Strategy includes the principle to be a connected and active city with a range of safe and effective transport options, including private vehicles, walking, cycling and access to public transport.


All road legal vehicles.


We are currently monitoring the situation.

We will consider the future of parking as the safety of all road users is a key consideration when developing concept designs.


Not currently. An option such as this would have to be carefully considered in the wider context of Kenepuru Drive and the potential safety risks associated with four-lane arterial roads.


Yes, the Kenepuru Drive Culvert immediately north of Ambulance Drive was reassessed in 2018 and 2019 and was found to be capable of carrying heavy vehicles (HN-HO-72 and HPMV traffic loading) without restriction.
