Tonkin Highway Grade Separated Interchanges (Hale Road and Welshpool Road)

Project
Proposal description: 

The Commissioner of Main Roads Western Australia (Main Roads) is proposing to widen Tonkin Highway from south of Roe Highway to approximately one kilometre north of Kelvin Road to a six-lane dual carriageway. The proposal includes construction of a half diamond interchange with north facing ramps at the Hale Road intersection in Forrestfield, and a grade-separated interchange at the intersection of Tonkin Highway and Welshpool Road in Wattle Grove. 

The proposal includes construction of a Principal Shared Path and installation of road, drainage and other associated infrastructure. 

Main Roads WA referred the proposal in November 2019, but suspended the 7 day public comment period at that time in response to stakeholder consultation. MRWA have now provided further information to the EPA regarding the design of the interchange. The referral information below has been updated to reflect this new information.
