Sewer, Active Transportation and Paving Upgrades
The District of Squamish is implementing capital project upgrades along Mamquam Road this summer and fall. These upgrades include a new sewer line, new sidewalk and bike paths, and road repaving, each of which are intended to make significant improvements to the area.
Work will take place in phases over the next four to five months, beginning with the sewer project in late June. The sewer project will be followed by the construction of the new sidewalk and bike path, and lastly with the road paving which is anticipated to be finished in late fall.
Timeframe: Late June to late fall
Project Area:
Sewer Upgrades
Project Area: Willow Crescent (west) to Glenalder Place on the east side of Highway 99.
Project Scope: The scope of this work includes upgrading the sewer pipe to accommodate for future growth. The project will begin at Willow Crescent and move east as the project progresses. The sewer pipe alignment will be placed under the middle of Mamquam Road where it will connect with existing infrastructure.

Project Impacts:
Phase 1 to 4: (Willow Crescent to Highway 99)
- Phased road closures, including full 24/7 road closures, on the west side of Highway 99 will be required due to the depth of the sewer pipe and the size of the excavation and dewatering required in order to complete this work.
- Construction hours will take place between 7 a.m. and 7 p.m. Monday through Friday, however, dewatering pumps will be in operation on a 24/7 basis.
Parking Impacts:
Parking will be impacted in the construction area. All measures will be taken to maximize parking availability. Parking will be opened as the project zone progresses to the east.
Traffic Impacts:
- Traffic pattern changes for construction;
- Pedestrian and cyclist access will be maintained throughout construction;
- Expect delays.
Transit Impacts:
- Starting July 9, 2021, the route 2 Highlands will detour on the highway between Centennial and Mamquam Rd east of the highway (it will not run through the project area). Two bus stops on Mamquam Rd between Government Rd and the highway will be closed. Two bus stops on Government Road between the Mamquam River and Mamquam Rd will only serve the route 9 Quest.
Timing:
- Phases 1 and 2: Approximately 10 weeks
- Phase 3: Approximately six weeks
- Phase 4: Approximately four weeks
Active Transportation Project
The District of Squamish is upgrading the pedestrian and cycling routes along Mamquam Road between Government Road and Highway 99.
Scope of work:
Active transportation upgrades include:
- Completion of a sidewalk on the north side between Willow Park and Highway 99
- Protected bike lane on the north side
- New on-street bike lane on the south side
Public Engagement:
A letter was delivered to 500+ area residents with a link to an online survey to gather resident feedback on the concept design.
Changes to the original design:
Street Parking:
- Adjustments to the crosswalk and bus stop will allow for increased parking on the north side of Mamquam Road;
- Parking will be removed on the south side of Mamquam Road to accommodate an on-street bike lane;
- Efforts have been made to minimize the overall net loss of parking which, estimated to be four stalls.
Crosswalks:
- Both crosswalks include enhanced safety measures such as narrowed crossing distances and improved alignments;
- The eastern crosswalk has been moved 25 metres east to Willow Crescent.
Speed
- Additional curb bulges at the crosswalk locations will narrow the road width which encourages slower speeds.
Project Timeline:
Work is expected to begin in mid-August and is expected to be complete in 2022.
Project Impacts:
- Phased, temporary parking restrictions along north shoulder.
- Pedestrian and cyclist access will be maintained throughout construction.
Paving Project
Roadway paving and paving of parking stalls will occur at the end of the project.
