Great news for Gungahlin commuters - the demolition works on the GDE bridge site have finished and the Barton Highway is open again.

However, the collapse and resulting traffic mayhem have served to underline the precarious state of our key commute routes.

Completion of the four-laning of Gungahlin Drive will help a little for some people and destinations. But we desperately need the bottlenecks on Flemington Road fixed, and the go-kart track that is Gundaroo Drive/William Slim Drive upgraded for people who commute from the west side and to Belconnen.
