The Five Creeks Stormwater Flood Protection Project began in 2019 and construction has been completed from the waterfront at the foot of 31st Street up to the Upper Levels Highway at the Westmount exit. In August 2020, construction crews ran into unanticipated ground conditions within the Highway 1 right-of-way, while tunnelling under Highway 1 at the Exit 7 westbound off-ramp and the work was paused. Work to complete the highway crossing has now re-started.
Construction will occur Monday to Friday, between 7:30 a.m. to 5:30 p.m., and Saturdays between and 8 a.m. to 5 p.m. if required.
May 10 update
Starting on Wednesday, May 11, Highway 1 Westbound Exit 7/Westmount Road/Westridge Avenue will be closed until approximately August 30 to allow for the tunnelling works to install the stormwater diversion crossings underneath Highway 1.
As a result of the closure, westbound traffic seeking to exit Highway 1 at Exit 7/Westmount Road/Westridge Avenue will be detoured via Highway 1 Exit 4/Woodgreen Drive/Headland Drive. Drivers are advised to follow the detour route posted on construction signage.
Highway 1 westbound on-ramp Exit 8/Cypress Bowl Road will be closed for approximately nine weeks, starting on Monday, May 16 to allow for the installation of the East Leg of the stormwater diversion system.
This closure will impact traffic seeking to enter Highway 1 westbound at on-ramp Exit 8/Cypress Bowl Road. Drivers are advised to follow the posted construction signage.
Blasting work will begin on the north side of Highway 1, adjacent to the Exit 7 westbound off-ramp on Monday, May 16. Blasting is required to create an entry point for the east stormmain crossing, and all work will be carefully considered and kept to a minimum. It is anticipated that blasting will take two to three weeks, or as required by ground conditions. All blasting will be overseen by a qualified professional working within the best practices guide for urban blasting operations and will be completed in accordance with District regulations and bylaws.
Upon completing the underground pipe crossings, construction will begin to tie-in the crossings into the existing diversion system along the 3300 and 3400 blocks of Westmount Road.
District road restoration and improvements
Road restoration and planned District capital road improvement works that were temporarily put on hold will resume once the Five Creeks Stormwater Flood Protection Project construction is no longer impacting the same roadways. These works include cycling and pedestrian safety improvements including sidewalk and curb upgrades, pavement markings, sightline improvements, bicycle lanes, accessibility improvements and installation of speed humps.
