ANOTHER weekend closure is planned at the Wanneroo Road-Joondalup Drive intersection so flyover bridge beams can be installed this month.
Main Roads has advised it plans to close the intersection after 8pm on Friday, November 22 until 5am on Monday, November 25 so work crews can safely install 16 bridge beams, which weigh 120 tonnes.
There will be detours in place, following the same routes at the July weekend closure.
The right turn from Joondalup Drive into Drovers Place will be re-opened for that weekend while the roundabout is closed to allow people to access the Drovers business precinct, and there will be access to the shops for motorists travelling north on Wanneroo Road.
The lefthand turn from Joondalup Drive into St Stephens Crescent will remain open, but vehicles will not be able to turn left onto Joondalup Drive.
Main Roads has advised people heading east or west to use Ocean Reef Road or Neerabup Drive, and those heading north or south to use Mitchell Freeway or Pinjar Road for the weekend.
It said pedestrians and cyclists will still have access through the intersection via the current detoured paths, and bus routes 390T, 390F, 391T, 391F, 467T, 468T would detour around the closed intersection.
The first two upper sections of bridge piers that will support the beams were installed last weekend on the eastern side of the intersection.
Contractors are expected to work 24/7 during the weekend closure, using cranes to install four beams for each span, which will be 28-33m long and 5m wide.
Following the beam installation, works will start on preparing the steel reinforcement for the 200mm concrete slab that will be laid on top of the beams.
In the lead up to the closure, there will be out of hours work, including between 7pm and 7am tonight, November 1-2 and November 4-8.
Sunday work is also planned between 8am and 5pm on November 10 and 17.
Main Roads expects traffic will be able to use the interchange bridge by April, with the $50 milllion project due to finish in mid-2020.
It plans to start works on Clarkson Avenue and Wanneroo Road intersection, Cheriton Drive and Joondalup Drive roundabout, and Burns Beach Road roundabout in the new year.
