Major traffic-pattern changes for Highway 1 overpass removal this weekend

Oct 2 2026, 4:44 pm

Work to widen Highway 1 through the Fraser Valley continues to progress this fall, and drivers are being notified that a major phase of the project will impact commutes starting on Friday, Oct. 2.

The Government of B.C. announced that traffic-pattern changes are planned on Highway 11 at Highway 1, as part of the widening and upgrade of the Trans-Canada Highway through the Lower Mainland.

Drivers are warned that several traffic diversions will be in place from 9 p.m. on Friday, Oct. 2 to 5 a.m. on Monday, Oct. 5 to allow crews to safely demolish the Highway 11 overpass.

The new westbound on-ramp to Highway 1 from northbound Highway 11 will be closed throughout the weekend.

Drivers will be detoured via Marshall Road and McCallum Road.

As well, Highway 11 under Highway 1 will be reduced to one lane in each direction.

According to the Ministry of Transportation and Infrastructure, some work is weather-dependent, so the schedule of these traffic diversions might alter.

Commuters passing through the area are asked to give themselves additional travel time due to the traffic-pattern changes and to check for traffic and construction updates available via DriveBC.

“During construction, reduced speed limits of 50 km/h on Highway 11 and 80 km/h on Highway 1 will be in place,” added the Ministry.

“Drivers are reminded to slow down and use caution, obey signage and traffic-control personnel in the area, and watch for roadside workers.”

The latest construction work is part of the Fraser Valley Highway 1 Corridor Improvement Program.

The Ministry of Transportation and Infrastructure said online that the project will improve safety, reliability and capacity between 216th Street in Langley through to Chilliwack.

A wider highway will also enable the Government of B.C. to add improvements like HOV/EV lanes both east and westbound, bus-on-shoulder lanes in each direction, truck climbing lanes, and a truck staging area.
