Asphalt works at Mapleton Avenue and Well Station Drive Intersections - March/April 2017

As part of the final stages of work at the Mapleton Avenue and Well Station Drive intersections, an asphalt overlay will be placed.

This work will be undertaken on three nights at each intersection, in the last week of March at the Mapleton Avenue intersection and the first week of April 2017 at the Well Station Drive intersection. Exact dates are dependent on weather and scheduling. To reduce the impact on traffic the work will take place at night, from 7 pm to 6 am and will not occur on a Saturday or Sunday night.

During the work at the Mapleton Avenue intersection access in and out of Mapleton Avenue will not be available. Similarly, during the work at the Well Station Drive intersection access in and out of Well Station Drive will not be available.

Traffic switch - February 2017

Duplication of the section between Anthony Rolfe Avenue and Well Station Drive is about half complete. Traffic was diverted onto the new carriageway in February 2017 to carry out work on the existing roadway.

These changes include a new temporary layout of turning lanes at the Mapleton Avenue and Well Station Drive intersections. Motorists will need to take additional care and follow the signage and markings to ensure they are in the correct lanes.

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.

Other works on Horse Park Drive

Construction for the new suburb of Taylor will include the upgrade of the Mirrabei Drive and Gaston Way intersections. A new intersection to the west of Gaston Way will also be constructed.
