MAIN Roads has confirmed dates for the weekend intersection closure as part of the Wanneroo Road-Joondalup Drive interchange project.
After weather conditions delayed the planned closure twice last month, Main Roads today confirmed it will proceed this week, starting 8pm on Friday, July 12 and reopening 5am on Monday, July 15.
The closure will allow work crews to safely relocate all barriers and replace the existing traffic signals with a temporary roundabout configuration.
Detours will be in place to direct traffic around the intersection, with Joondalup Drive closed between Burns Beach and Pinjar roads, and Wanneroo Road closed between Flynn Drive and Clarkson Avenue.
Vehicles travelling north on Wanneroo Road will still be able to turn left and head west on Joondalup Drive, and to access the Drovers precinct.
Pedestrians and cyclists will still have access through the intersection via the current detoured paths.
The right hand turns in and out of St Stephens Crescent and Joondalup Drive will be permanently closed.
Right turn access between Drovers Place and Joondalup Drive will be permanently closed early Monday morning.
Bus routes 390T, 390F, 391T, 391F, 467T and 468T will detour around the closed intersection – visit www.transperth.wa.gov.au .
The second stage of interchange works will start following the reopening of the Wanneroo Road and Joondalup Drive intersection, focussing on building the Joondalup Drive bridge and ramps.
Vehicles will also be pushed to the outside of Joondalup Drive while works are undertaken in the middle of the road.
Temporary signal control will initially be set up on Wanneroo Road heading north near Drovers to assist with afternoon peak hours. The use and duration of the signals will be monitored and altered as required.
Ramps will be built in the middle of Joondalup Drive 200m long on the west side of the intersection and 90m long on the east side.
Bus stops will remain in the same locations as they are at present and barriers will remain in place until March 2020.
Out of hours works may also take place on Sunday, July 21 and 28 from 8am to 5pm, and night works from 7pm to 7am on July 15 to 20 and 22 to 27.
