We are currently investigating options to widen a 93 km section of South Western Highway between the Pemberton turnoff and Walpole.
The two lane road has a 6 m seal width, narrow gravel shoulders and steep batters, and covers a variety of terrain and significant rivers. There is a requirement to improve road safety and reduce run-off road crashes on this section of highway.
We are progressing planning in response to concerns raised by the community for the section of the highway south of Pemberton from Vasse Highway to Middleton Road.
Land is required from National Parks and possibly from some private properties, although this is expected to be minimal. The works are likely to reflect the existing highway alignment with no significant realignment or reconstruction proposed. However, these widening works are at least two years away due to time required to complete land dealings. The initial focus will be on the section north of Middleton Road to reflect business, tourism, safety impacts and traffic volumes with a preliminary design for the 10 km section north of Middleton Road currently being developed.
Scope of works
We plan to increase the seal width to ten metres, including the construction of fully sealed new shoulders. Where possible we will improve safety of road verges by flattening batter slopes and protecting or removing roadside hazards (predominantly large trees).
The extent of work is not yet determined and will be influenced by workshops with community representatives. Our aim is to work together to develop a solution that is fundamentally acceptable to all.
