UPDATE #17 Mosgiel Road Works

We’d like to thank residents, businesses and road users of Mosgiel for your continued patience with these road works, closures, detours and general traffic management.  While we originally planned to have this job completed in 6 weeks, further time has been needed.

Why the extra time?

Our pre-work ground testing showed some locations along the road parking lanes would need extra foundation repairs and we were prepared for that. However, once the road was opened up, our machinery simply began sinking on the poor backfill material over the water main pipes (pre-DCC backfill material) preventing us from laying asphalt then.  More extensive foundation repairs to the road shoulder (parking lanes) were needed. 

This extra work has provided challenges for both the community and project team with longer than anticipated closures of driveways and business accesses and a larger detour.

How did we tackle it?

Extra road crews were redirected, along with other contractors.  We appreciate their help at short notice.  We are in the peak of the road construction season, so these crews were and are committed to other projects so we’re balancing those commitments with keeping work going in Mosgiel. As a result, there are times when we don’t have the number of workers on site we want, but we are doing our best and are very conscious of the impact of this work on the community.

The asphalt season is short requiring air temperatures over 10 degrees for best results and our asphalt crew has a packed schedule, refined daily based on the weather.  Delays on the Mosgiel project because of the foundation issues meant hold ups to other projects they had booked, so they had to move onto those while the foundation repairs occurred.  We expect them back in town this weekend and they are currently transitioning from night shift to day shift to enable commencing asphalting in Mosgiel on Monday (Otago Anniversary day).

Why not work 24/7?

Although work could be at any time of day and on any day of the week, we don’t have enough crews to run two continuous shifts to operate 24/7 and we never intended to do this for many reasons including safety. 

We are also mindful of disruptions to residents overnight, so most of the work is being done during the daytime.   Early in the project we received complaints when we worked until 11 pm repairing water mains, so 10 pm is as late as we tend to go.

Two lanes not an option currently

We’ve been asked why we can’t put two lanes of traffic down the street at the moment and avoid the detours.  There are several reasons:

  1. There are pedestrian crossings build-outs along the road (near Bruce St) and toward Ayr St, which create pinch points where only one lane of traffic can pass.  It’s not practical to operate Stop/Go or manual traffic lights in these locations 24/7. 
  2. Running small detours around these areas isn’t an option as the local roads are too narrow and cannot handle highway vehicle movements. 
  3. The parking lanes/ shoulders, which have been repaired, are not designed for regular, repeated heavy vehicle use. Also, if this did happen, there’s a risk of damaging the water mains creating another disruption to fix them. 

Like you, we want to return your journeys, businesses and lives to normal and we are working to the best of our capacity to complete this project.


  • MONDAY 25 March (Anniversary Day) – MONDAY 2 April:  Our asphalt paving crew will be back to re-lay the foundation asphalt at the three open foundation sites and then commence the final surface on the entire northbound lane and parking bay from Burns St to Cargill St.
  • APPROX MONDAY 2 April:  Our road marking crew should be able to start re-marking the new asphalt surface.  This work will be done at night and again is weather dependent.
  • Once the asphalt crew is finished there will still be some work to ensure underground service covers are flush with the new road surface. 

We will remove detours and road closures as soon as it is safe to do so. 

Estimated project completion date is 5 April.

If you have any questions or concerns, please contact or contact the NZ Transport Agency call centre 0800 44 44 49.



To enable work to occur on the Hotel Taieri side of the road, we need to maintain the alternate detour.  We know this causes frustration, but there are no other alternative detours available and approved by the DCC.   

We will again close all side streets accessing the southbound lanes of Gordon Road and this includes Wickliffe, Park and Laing Streets.  We won’t have sufficient road width to be able to enable two-way traffic on Gordon Road between Park St and Hagart Alexander Drive, hence the need for a variation to the detour.

The current detour is highlighted in blue on the map below and the VARIATION detour is in red on the map. 

We can’t keep the St Mary’s bus stop active for public bus services during this temporary detour change, but the bus will continue to use the temporary stop at the corner of Church and Wickliffe Streets – refer orange stars. 

St Mary’s School bus services will have access to exit onto Gordon Road as there is no safe way to turn this bus around.  Our traffic management team is aware of the times of this service and will be on hand to assist.  There may be short delays to northbound traffic as we get this bus through.


We’ve got the Wellington Traffic Operations Centre manually controlling the traffic lights at the Hagart Alexander Drive and Gladstone Road traffic lights.  This is to override the current traffic light phasing setup and enable more traffic to flow from side streets such as Hagart Alexander Drive and ease congestion and delays as much as possible.  They will continue to do this while the alternative detour is in place. 

SH87 Detour


If you are accessing your property or a business over the new asphalt there are a few things you need to know:

  • please GO SLOW
  • DO NOT turn your wheel while your vehicle is stationary - otherwise you will rip up the asphalt and we’ll have to repair it, which will cause delays and more inconvenience to yourself, neighbours, other road users and businesses
  • Try to DRIVE STRAIGHT in and out of the property you are accessing.  Turn your well before or after passing over the asphalt
  • NO HARSH BRAKING OR ACCELERATION over the new surface
  • If you are uncomfortable, park on a side street and walk to the property.
  • NO HEAVY VEHICLES are permitted to drive on or over the new asphalt areas on the southbound half of the road.

Please share this information with friends, family, public transport users, or businesses who may be affected by this information.

Thank you for your patience. 


21 January 2019

Roadwork Commencing

We’re undertaking work on the main street of Mosgiel to repair its surface and large sections of the road foundation.  The work will take approximately 4-6 weeks to complete and we will start during the week of 21 January 2019. 

Area of the works

The work we undertake will be across the full width of the road, including parking spaces.  It will not affect the footpath, kerb or gutters.

The area of the repair work extends from the northern side of the intersection at Hagart Alexander Drive to just past Cargill Street. We’ve highlighted the area in the map to the right.

SH87 Gordon Rd

What you need to know

1.    Parking will be restricted

In the work area, on-street parking will be unavailable; use side streets instead. Please ensure your cars are not parked on the street when we commence work.

2.     Night work

Some work will be undertaken at night and it may be a little noisier than normal; you may also feel minor vibrations as we lift the existing surface.

3.     Businesses will be open

It’s important you still support them even if access is slightly more challenging.

4.     General travel on Gordon Road / State Highway 87

Traffic on Gordon Road will be down to one lane with stop/go priority to northbound travel.  If you travel southbound on Gordon Road or into Dunedin you are strongly encouraged to use Riccarton Road and State Highway 1 or Three Mile Hill to avoid congestion at both the Hagart Alexander Drive and Gladstone Road traffic lights. This will reduce delays to your travel.

5.     Traffic light sequencing

Traffic lights at Inglis St and Hagart Alexander Drive will be operating differently as we have to cut their trigger loops.  This means the phasing will be different and there may be more queuing than normal.  We’ll be keeping an eye on these particularly during peak times, but we recommend you take alternative routes to and from Mosgiel if you can.

6.     Heavy vehicles

Are required to detour around Mosgiel unless servicing the shops in the work area; no trailer units will be permitted to pass during the work. For access through or to the northern end of Mosgiel, please use Riccarton Road (up to 50MAX only) and SH86 Allanton for all other heavy vehicles.

7.     Gordon Road side streets

The streets highlighted in the map may be closed from time to time during the work.

8.     The road surface will be bumpy

You can expect a very bumpy road surface once we’ve lifted the top layer.  You’ll see, and feel, manhole covers and fire hydrants sticking up so keeping your speed to 30km/hr is essential.

9.     Bus services

Bus stops will be affected on Gordon Road and the Otago Regional Council will have a temporary bus route and stops in place on Church Street. Look for information on the Otago Regional Council website soon.

10.    Emergency services

Access will be enabled at all times

11.    Resident / business driveway access

Driveway access to residents and businesses will be restricted for a period during the work.  It could be affected for anywhere from 2 hours to about 3 days.  At the Inglis St intersection, this closure could be for longer as extensive work is occurring at this location.  You’ll need to plan ahead and ensure all vehicles you wish to use are out of your drive before our work commences. 

12.    Pedestrians will have limited passage across State Highway 87 / Gordon Road

Footpaths will be unaffected by the work, but pedestrians will not be able to cross the road through the active parts of the work site; please follow our signage.  This is to keep you safe from our machinery.  If you use a mobility device or scooter, please note that there will be larger than the normal drop at the kerb once the surface is lifted.  Please take immense care at all times.  

What we ask of you

During our works, we ask that you:

  • understand that this work must be done and that we are minimising the impact on you as best we can
  • support businesses near the works by still visiting them

  • plan your journeys to avoid the active work sites as much as possible

  • keep an eye out for emergency vehicles needing to get through traffic queues

  • be patient with us and each other especially if you are in traffic queues

  • keep your speeds down where they are reduced as it keeps everyone safer

  • refrain from entering the active worksite when we are not on site as you could get injured

  • avoid interfering with our road cones and signage
