Southern Outlet Olinda Grove Interchange - Deceleration Lane

The Department of State Growth has undertaken work to extend and widen the existing deceleration lane on the city bound approach to the Southern Outlet / Olinda Grove interchange.


The work was undertaken on the city bound approach to the Southern Outlet / Olinda Grove interchange near Mount Nelson.

Why is the Department of State Growth doing work on this road?

The Southern Outlet near the top of Mt Nelson is one of Tasmania’s busiest roads, particularly during the morning peak, when it provides a key connection for traffic travelling to Mt Nelson and Sandy Bay, including to Hobart College and the University of Tasmania.

In recent times, high numbers of vehicles exiting at the Olinda Grove interchange has resulted in traffic queues extending back onto the Southern Outlet.

The work involved extending the existing deceleration lane by approximately 300 metres southwards, round the left-hand curve and onto the straight prior to the Olinda Grove overpass.  Extending the deceleration lane will improve safety by creating better visibility and more space for vehicles to queue outside the lane of traffic.  This will also assist in managing the queue arising from the roundabout on Hobart City Council’s Olinda Grove Road.
