Construction Updates

Tree Clearing (Summer 2019)

Tree clearing is required along the south side of Highway 1, between Mountain Highway and Lynn Creek in preparation for the construction of the new Mountain Highway Eastbound On-ramp, relocation of Keith Creek and realignment of the Keith Creek trail.

Tree removal will commence when the wildlife salvaging, bird nest surveys and tree assessments are completed, and once Keith Creek has been switched over to the new creek channel in mid-August 2019. Landscaping of the new creek area will occur in the Fall 2019 and once complete a total of 815 coniferous trees, 630 deciduous trees and 7628 shrubs will have been planted along the new Keith Creek and trail. Please see rendering developed from design drawings of the Keith Creek Relocation below.

It is important to note that due to the close proximity of trees to the highway some tree clearing will occur at night when temporary lane closures can be implemented so that traffic can be moved to a safe distance from tree falling activities.

Notification letters for Keith Creek tree clearing have been distributed to nearby residents.

Sound Mitigation

The Mountain Highway Interchange has utilized various methods of sound mitigation to address traffic noise concerns.

Learn more about noise assessments and sound mitigation by reading the Mountain Highway Interchange Noise Assessment and Sound Mitigation Information Sheet.

Lynn Creek Trails

Lynn Creek East Footpath Closure

The east side Lynn Creek trail will be closed from July 3, 2019 to August 30, 2019 and the west side Lynn Creek trail will be closed until Spring 2020.

Construction of the new Lynn Creek bridges upstream and downstream of the existing Highway 1 Lynn Creek Bridge started in June 2018. Construction is set to begin on the Keith Creek Realignment and new Lynn Creek Bridges and for public safety the trails will be closed February 18, 2019 until further notice.  We understand how important the trails are to the community and will make every effort to reopen them when it is safe to do so.  Please obey the posted signs and thank you for your cooperation.

Trail Closures and Detours
Special consideration for the east side trail have been made to ensure access to Lynnmour Elementary School for students and parents during school months.
We apologize for any inconvenience the trail closures may cause and will continue to reassess during construction to seek ways to reduce closure durations and impacts. Please obey traffic control and use caution near the construction work zone.

Keith Creek Relocation

The Lower Lynn Improvements will impact Keith Creek therefore it will be relocated further south of the highway. Relocation of Keith creek provides an opportunity to improve aquatic habitat and water quality along with increasing this important salmon spawning area by 25%. When completed the Keith Creek and new trail will be landscaped in a park like setting which includes the planting of 2,400 trees and 11,000 shrubs.

Salop Trail

Construction works in the vicinity of Salop Trail have necessitated extending the closure of the Salop Trail between Shavington Street and Cloverley Street to ensure the safety of pedestrians and cyclists during the installation of the Metro Vancouver Sanitary Sewer Siphon.

This trail closure will be in effect from March 9th, 2018 to project completion August 31st, 2019. A detour for pedestrians and cyclists has been signed on location. Please obey traffic control and use caution near the construction work zone.
