Main Roads crews have continued efforts to repair severe road and bridge damage on the 80 kilometre section of South Coast Highway east of Ravensthorpe to Munglinup.
Repairs to the Jerdacuttup Bridge was expected to be completed on Friday afternoon.
The OldfieldBridge has had one lane reopened but there is no access beyond the Hatfield Road culvert which was severely scoured by flood waters.
Work to reinstate the culvert will continue over the weekend and Main Roads anticipates reopening the entire link to traffic early next week.
Work will also begin next week on constructing a temporary causeway on the western side of Ravensthorpe at the Phillips River where the traffic bridge was destroyed last weekend.
A detour north of the river crossing will remain in place until the temporary causeway is constructed in six to eight weeks time.
All major roads in the Wheatbelt have reopened to all vehicles although extreme caution is advised.
Over mass loads have been temporarily banned from the Williams River Bridge in Williams on the Albany Highway until minor strengthening works are carried out next week.
Road users should use extreme caution when travelling reopened roads, and go to the Main Roads’ website for the latest road condition detour information.
