Construction contract announced

The construction contract for the highway upgrade project was awarded to Downer/ Seymour Whyte. The joint venture will build the four lanes of new divided road between Mullers Lane at Berry and the Cambewarra Road roundabout at Bomaderry. They will also build temporary roads and carry out road work for the safety of motorists and workers during construction.

Major construction is on track to begin in mid 2018.

We're getting ready for construction

We are at the final stages of relocating utilities before major construction of the Berry to Bomaderry upgrade begins.

Endeavour Energy has been engaged by Roads and Maritime to relocate electrical utility services in preparation for major construction of the Berry to Bomaderry upgrade to start.  Work will continue until August 2018 between Cambewarra Road, Bomaderry and Croziers Road, Berry. There will be impacts to power supply at some properties. You will receive a notice from Endeavour Energy notifying you if your property will be impacted.

Motorists are also advised of changed traffic conditions from Monday 9 July on the Princes Highway between Berry and Bomaderry for the removal of overhead electrical utilities. Work will be carried out along this stretch of highway on weekdays between 9am and 3pm and take about four weeks to complete, weather permitting.

Traffic control and a reduced speed limit of 40km/h will be in place at times for the safety of workers and motorists. Motorists are advised to plan their journey, with delays of up to 10 minutes expected.

Improving road safety and accessibility into Croziers Road, Jaspers Brush, from the highway

In March 2018, a temporary protected right turning lane was built at the Croziers Road and Princes Highway intersection to improve road safety and accessibility for motorists. View or download the Croziers Road diagram (PDF, 169Kb) to see the range of safety work that has been completed or is in development at the intersection.

The work includes a designated right turning lane, removal of the bus stop and the installation of additional guard rails.

Speed limit reduced to 80km/h

For the safety of workers, the speed limit between Mullers Lane, Berry and Cambewarra Road, Bomaderry has been reduced to 80km/h

Motorists should plan their trip, allow for extra travel time, keep to speed limits and follow the direction of traffic control and road signs.

Work will generally be carried out Monday to Friday between 7am and 6pm and reduced roadwork speed limits may apply. There will be temporary stopping of highway traffic for up to two minutes as required while work is progressing.
