The Signal Terrace entrance into Cockburn Central station will be closed until February 6, with work beginning yesterday on upgrades to the intersection.
Improvements will include a repaved road surface, new drainage, kerbs and parking bays on Midgegoroo Avenue, formerly the section of North Lake Road adjacent to the train station.
From February 7, motorists will no longer be free to turn right into Stockton Bend from Midgegoroo Avenue, meaning it will become a left-in, left-out intersection. Signal Terrace will offer motorists travelling north an entrance into the increasingly busy precinct.
Council expects the roadworks to be completed by the end of February.
Further east, upgrades to Warton Road mean the strip between Jandakot Road and Armadale Road will be closed to traffic from this Wednesday until mid-February.
Signed detours will push eastbound traffic that would usually use Warton Road onto Solomon Road, while westbound traffic will be directed through Nicholson Road.
Council is also set to start work on turning North Lake Road between Hammond Road and Kentucky Court into a dual carriageway.
Plans for the $4.2 million upgrade show North Lake Road will have four traffic lanes, two each way, with an island. Landscaping, drainage, lighting, and on-road bicycle lanes are also part of the project, expected to be finished in June.
