Channel Highway - Bonnet Hill Safety Improvements

The Tasmanian Government has committed to improving the safety for all road users travelling along the Channel Highway in Bonnet Hill. The shoulder sealing and line marking work is based and builds upon the design strategy outlined in the Kingborough Council's report On Road Bike Lane – Channel Highway Preliminary Design 2009.


The project site is located on the Channel Highway in Bonnet Hill, from Proctors Road to Baringa Road in Taroona.

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

The safety improvements will provide increased space for all road users (including cyclists) to travel safely through the uphill sections of Bonnet Hill. Work includes:

  • Widened and sealed shoulders to provide a safer shared environment for all road users;
  • Improved delineation on curves (chevrons and guideposts) to reduce run-off-road risk.

Current Status - 10 May 2017

Two sites were identified for safety improvements in the 2016/17 construction season.  Construction commenced in December 2016 and is nearing completion.  The final stage of work involves asphalting and line marking and is weather dependent. Work is anticipated to be completed by the end of May 2017.

The two sites are located at:

Site E: Derwent Rise Embankment – 350 metre uphill section either side of the Baringa Road junction.   Work started in December 2016 just down from the Baringa Road junction area up to the sealed bus-stop above the junction. Construction and sealing work has been completed, line-marking will be undertaken from the end of the existing cycle lane up to the sealed bus-stop above the junction. 

Site F: Tyndall Embankment – 450 metre uphill lane. These works commenced in February 2017 and will be completed by the end of May 2017.

Traffic signals will be operating at the work sites.  Delays to the travelling public can be expected in the vicinity of the construction works for the duration of the project.  

At least one lane will be open at all times with two lanes open outside working hours.  A lower speed zone may apply out of hours while works are being undertaken. Pedestrian access and accesses to private properties will also be maintained.

There may be some material over the sealed surface, which the contractor will manage, please use caution when approaching work sites, especially in the downhill direction.

Completed Works

Works completed in 2015/16 construction season included shoulder widening at four key locations:

Site A: Just past Proctors Road to Tyndall Road junction – 750 metres (uphill lane);

Site B: Just past Illawong Crescent to just past Shot Tower – 1010 metres (uphill lane);

Site C: Harpers Road to Lynden Road – 300 metres (uphill lane);

Site D: Taronga Road to Bonnie Brae Road– 100 metres (uphill lane).

Future Works

Further safety improvements are programmed for the 2017/18 construction season.  

The final stages will be undertaken in 2018/19 following completion of design details on these more technically challenging sections.
