Highway 99 northbound and southbound will be closed to traffic overnight for up to eight consecutive nights beginning Friday, July 18, 2025, for Steveston Interchange construction.  

During the closures, vehicles travelling on Highway 99 will be detoured using the on- and off-ramps at Steveston Highway.

The closures are needed so heavy-lift cranes can lift the main-span concrete girders into place to form part of Phase 2 of the new five-lane Steveston Interchange spanning Highway 99. Each of the 11 main-span girders weighs 50 tonnes and is 35 metres long.   

To minimize traffic interruptions, work will only take place during the following times:

• July 18-19: 10 p.m. to 7 a.m.
• July 20-25: 10 p.m. to 4:30 a.m.

As is currently the case, the Steveston Highway northbound loop ramp onto Highway 99 will remain closed, with traffic rerouted to access the north side on-ramp via left turn lanes. East/west travel on Steveston Highway will be maintained for vehicles, pedestrians and cyclists.

Existing transit stops will be maintained in all directions. Drivers can expect minor delays and are asked to use caution through the detour.

The Steveston Interchange Project is on track to be completed in fall 2025.
