Sorry we are in your way, we are widening the road to install more safety barriers along Dyers Pass Road to make it safer for everyone. This is the second stage of work, expect delays and night work. Thank you for your patience.

Between July and December 2022 we’ll be widening the road and installing more safety barriers in several high-risk locations to make Dyers Pass Road safer for everyone.

There have been recognised safety issues on Dyers Pass Road for years. The safety barriers and road widening will improve safety by reducing the risk when driving or cycling mistakes might have resulted in a vehicle leaving the road.

We installed almost three kilometres of guardrails in 2021 at other high-risk locations, and we’re returning to make it even safer.

When we finish this next stage of work, almost 75% of Dyers Pass Road will have safety barriers.

We learnt a few tough lessons during the previous stage of work in 2021 and have made some changes to minimise disruption where we can.

Our contractor will be doing their best to minimise the disruption.

People travelling on Dyers Pass Road should factor in an extra 20 minutes plus the normal travel time of ten minutes, and if possible, use the Lyttelton tunnel or Gebbies Pass until the work is completed in December.

We realise the frustrations caused in stage one with multiple worksites and stop/go causing lengthy delays.

This time, rather than working on multiple sites and using stop/go controls, our contractors will have only two work sites underway. 

The road will be down to one lane and 30km/h through the work area. Traffic will be controlled by temporary traffic lights – smarter ones than those used in stage one work in 2021.

We’re not able to open the road to two lanes of traffic on weekends or public holidays but we’ll be working closely with the contractor to minimise single-lane closures during the work.

It’s not an easy task to work on a steep, narrow and windy road so for the safety of crews working on the road, we ask that people driving or biking over Dyers Pass Road respect the traffic management. The traffic signals are critical to ensuring workers and road users are safe.

During the day the machinery will be parked on the roadside. This can look like no work is happening, however, the machinery is being used at night time.

Visitors will still be able to access the park via Victoria Park Road. Please observe the normal opening and closing times of the gates(external link)

Victoria Park Road is not a legal road, so it cannot be used to detour traffic. It’s also not designed or suitable for high volumes of traffic.

We know the work is disruptive and we’ve listened to your feedback from stage one. Changes have been made to improve traffic flow while we’re working.

If you can, we encourage road users to detour via the Lyttelton tunnel or Gebbies Pass. Otherwise, expect delays of around 20 minutes plus travel time.

The total journey time from Governors Bay to The Sign of the Takahe is approximately 30 minutes total. Look out for the electronic travel time boards to help you decide which route to take.

To complete the work as quickly as possible, and to carry out more disruptive work we’ll be doing night work from 7.30pm to 6am Sunday to Friday for the duration of the project. Dyers Pass Road will be closed during these times. A detour will be in place via the Lyttelton tunnel or Gebbies Pass.

Night work will start on Sunday 10 July 2022 and the project is due to be completed in December 2022.

Installing safety barriers sounds like an easy task, but on a steep and narrow road like Dyers Pass, it’s a bit trickier.

Before we can install the safety barriers, we need to:

  • Trim back overhanging rocks.
  • Make a new drainage channel.
  • Build concrete structures and retaining walls to support the widened road and safety barriers.
  • Widen parts of the road.
  • Seal the road shoulders.

This work is additional to work carried out on Dyers Pass Road in 2021.

Further funding has been set aside in our Long Term Plan (LTP) to complete this work, and it needs to be finished by the end of 2022 to meet our LTP requirements. It has a budgeted cost of around $3.5 million.

The signals we’re using on the city side are smart signals which can adapt to changing conditions. These will be monitored by our Real-Time Traffic Operations Team.

They’re far more responsive than regular temporary lights and allow for remote monitoring so we can keep an eye on traffic flows.

They’re also much smarter at detecting cyclists and will allow more time in the green light phase to allow a cycle to clear the site.

This will only be triggered when a cyclist is detected by the signals in the uphill direction from the city side.

Temporary traffic lights will be used on the Governors Bay side. These are also more flexible than those used during stage one.

If you have been waiting at the lights for more than 10 minutes please call our dedicated 24-hour phone number 027 227 5849. We appreciate your patience.

We’re urging cyclists to follow the traffic management on Dyers Pass Road while we’re working.

We’ve made some changes this time around to make it safer, and to improve traffic flow during the work.

This time, we’re using a set of smart traffic signals that can be monitored by our Real-Time Traffic Operations Team, allowing us to respond to any issues quickly.

These signals include advanced cycle detection, which means that when a cycle is detected the signal will allow more time in the green light phase to allow that cycle to clear the site. This feature will only be activated if a cycle is detected, or if a cyclist pushes the button on the traffic lights.

When the cycle light is red, it is not safe to pass through the worksite, even if it looks like no traffic is coming from the opposite direction.  

Delays of 20 minutes plus travel time should be expected on Dyers Pass Road during the work.

We also have a separate space for cyclists to wait on the roadside so that they don’t need to queue with traffic.

Our team will be working closely with emergency services.

We have established access procedures with emergency service dispatchers, so we can coordinate access through the site at any time of the day or night in the event of an emergency.

Emergency services will also receive regular status reports and updates throughout the work.

We update key emergency services contacts as the work location and site conditions change.

The best way to keep updated about the work, including night closures and changes to traffic management is to sign up to receive regular email newsletters.

We’re here to help. Let us know if you have any questions about the work or have any access needs we should know about.

If you have any questions or concerns about the work, please phone Higgins Contractors on 027 227 5849.

The team will be available at Sign of the Takahe from 1pm to 2pm each fortnight. We will update this page with dates soon.
