Erskine to Blina SLK 2381-2394
Phase:Clearing proposal closed for submission
Main Roads Western Australia proposes to upgrade the Great Northern Highway (GNH) between Straight Line Kilometre (SLK) 2381 to 2394 near the Camballin floodplain, referred to as the “Erskine to Blina” section. The proposed works will reduce the frequency of road closures due to seasonal flooding events, increasing haulage connectivity throughout the wet season and improving the safety of the infrastructure.
The current seal is 7.5 m in width, with sections of poor rideability. The proposed works include widening the road seal from 7.5 m to 11 m, upgrades to culverts, additional culverts and increased floodway capacity, which will improve road safety for motorists. Increased seal widths are required to meet the regional improvement strategy and Road Safety Management System (ROSMA) interim safety standards.
In relation to the proposed native vegetation clearing, the upgrade will comprise the following components:
1) Material investigation and extraction;
2) Widening and sealing the existing road formation and shoulders;
3) Road drainage upgrades; and
4) Additional supporting infrastructure as required.
