Safety Upgrade on Augusta Highway at Mambray Creek

29 February 2016

Stage two of works to improve safety for road users at the Augusta Highway intersection with Spencer and Park Roads at Mambray Creek are currently underway.

The Department of Planning, Transport and Infrastructure (DPTI) advises that these works include the realignment of Spencer Road to create a staggered T-junction, improving the requirement to give way on approach to the Augusta Highway.

The entrance to the adjacent rest area will also be relocated to Spencer Road, reducing the number of accesses on the Augusta Highway.

These works are in addition to the improvements completed in March last year, which included the extension of the south bound left-hand turn lane and the construction of a sheltered right-turn lane into Park Road.

These improvements will potentially reduce the risk of rear-end and right-angle crashes at this location.

DPTI will make every effort to minimise the impact on road users, with works being undertaken between 7.00am and 5.00pm on weekdays and weekends over 13 day blocks with 3 day breaks until completed.

The road will remain open, with traffic restricted to one lane under traffic control when required and a 25 km/h speed restriction while workers are on site. Other speed restrictions may apply subject to onsite conditions.

These works are expected to be completed by April 2016, weather permitting.

Once completed, these safety initiatives represent a $1.3 million investment from the Motor Accident Commission’s Road Safety Infrastructure Fund.

DPTI thanks motorists for their patience while these important road safety improvements are undertaken.
