Mamquam Road Upgrades
Update: December 1, 2021: project delayed to 2022
Work on the Highway 99 section of the Mamquam Road sewer upgrade project will be delayed until 2022 due to a combination of inclement weather and length of time required in order to plan and execute a project of this scale. Unsuccessful drilling attempts under Highway 99 forced the unexpected delay which now requires open-trench excavation across the highway. Mamquam Road between Government Road and Highway 99 has reopened and will close again when the project resumes in 2022.
View details of the delay.

Highlights
- Mamquam East / Highway 99 Intersection lanes (and Southbound Highway 99 left turn) have reopened;
- Mamquam West / Highway 99 lanes (and Northbound Highway 99 left turn) have reopened;
- Road paving work will be completed with additional paving anticipated to continue in 2022;
- Active Transportation Project construction along Mamquam West is ongoing and will be completed in 2022.
- The Highway 99 crossing and remaining eastern section to Glenalder Place will be completed in 2022.
Sewer, Active Transportation and Paving Upgrades
The District of Squamish is implementing capital project upgrades along Mamquam Road. 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.
The sewer project will be followed by the construction of the new sidewalk and bike path, and lastly with the road paving.
Timeframe: 2022
Project Area:
Sewer Upgrades
Project Area:Willow Crescent (west) to Glenalder Place on the east side of Highway 99.
Project Scope: The Mamquam Sewer Project involves replacing and upsizing the sewer line from Willow Crescent (West) to Glenalder Place. Work on this project is delayed due to a combination of ground conditions and length of time required to plan and execute a project of this scale. The project is now substantially complete from Willow Crescent (West) to Highway 99, however unsuccessful drilling attempts forced unexpected delays and the project now requires a new crossing design for Highway 99.
The project team is developing an alternative crossing design and plans to complete construction in 2022 (construction dates dependent on design). The work will focus around Highway 99 with some road impacts anticipated. Further information will be provided when the project design is complete, and the full impacts are understood.

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.
Active Transportation Project
The Active Transportation Project includes a new sidewalk, tree-lined boulevard, and bike path on a large portion of the north side of Mamquam Road between Government Road and Highway 99, and an on-street bike path and shoulder widening on the south side. This project was delayed due to the adjusted timeline of the sewer project. Work will resume in the spring 2022 and is anticipated to be complete by the summer.
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
View the detailed drawings.
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 be complete in 2022.
Project Impacts:
- Phased, temporary parking restrictions along north shoulder.
- Pedestrian and cyclist access will be maintained throughout construction.
Paving Project
The road repaving project includes paving the majority of Mamquam Road from Government Road to Highway 99. A portion of this work was completed this year with the remainder being completed in summer 2022 when weather conditions will not be a factor.
