Asphalt and median strip works - May 2017

As part of the final stages of the upgrade of Horse Park Drive between Anthony Rolfe Avenue and Well Station Drive there will be asphalt and median strip work and the traffic lights at the Mapleton Avenue intersection will be activated.

The following traffic changes are in place during May (weather permitting) to enable this work:

  • Monday 22 May (previously Saturday 20 May, delayed due to forecast rain) – median strip works commence and Mapleton Avenue intersection traffic light activation. To enable the work, a traffic switch will direct all traffic to the left-hand slow lanes in each direction on Horse Park Drive (i.e. moving Gungahlin-bound traffic back to the slow lane of the existing road). Please note that the new traffic lights at Mapleton Avenue will come into operation during this traffic switch.
  • Tuesday 23 May – final asphalt applied to the left lane of the city-bound carriageway. Traffic will use the right lane while this work is carried out, and there will be no traffic detours.
  • Wednesday 24 May and Thursday 25 May – final asphalt will be applied to the right lane of the city-bound carriageway. Traffic will use the left lane while the work is carried out, and there will be periods where traffic will be blocked from turning right into and out of Mapleton Avenue and Well Station Drive. This will affect only one of these two intersections at a time. However, please use alternate routes to avoid delays. Detours will be in place during the right turn restrictions at these intersections.

Exact dates depend on weather and scheduling. To reduce the impact on traffic the work will take place during the day, outside peak periods (between 9am and 3pm).

Construction work will be managed to minimise impacts on motorists and local residents, though drivers and cyclists may experience some delays. We will continue to keep motorists, local residents and businesses updated on the project and its progress via this website, social media, on-site signs and through the media.

The Horse Park Drive upgrade coincides with the work on Throsby, which started in October 2015, and other projects in Gungahlin (including extensions of The Valley Avenue and Manning Clark Crescent),  and upgrades to intersections on the Barton Highway, Gundaroo Drive and William Slim Drive.
