Brand Highway (H004) Passing Lane - SLK 166

Main Roads is proposing to construct a northbound passing lane along Brand Highway between SLK 166.65 – 168.75. The proposal will require the clearing of up to 1.89 hectares (ha) of native vegetation. The road alignment follows a steep grade along this section with horizontal curves, which provides inadequate sight distance for traffic to overtake large freight and slow-moving vehicles. At these steep grade locations, heavy vehicle speeds fall below 90 km/h causing driver frustration and prompting unsafe overtaking manoeuvres.

Constructing a new northbound overtaking lane at this location will improve safety and increase the efficiency of heavy vehicles by reducing travel time.
