Construction & Traffic Updates
Starting the week of February 17 and lasting for approximately three months, crews will begin stone column installation and pile driving work in the southwest and southeast quadrants of the Project.
UPDATED January 31: Previously scheduled work on the weekend of January 31-February 3 has been postponed due to the forecasted winter weather event. Work is now scheduled to begin on February 7, 2025. Please visit our current work page for the latest status updates.
On the weekends of January 31-February 3, February 7-10 and February 21-24, drivers can anticipate delays around the Steveston Interchange Project as crews work to remove the existing overpass.
Please consider alternate routes when possible, such as the Alex Fraser Bridge via Highway 91.
With the north half of the new overpass now completed, vehicle traffic will shift onto the north structure in two phases. Overnight on January 15, westbound traffic will be rerouted to the new overpass, with new lane markings to direct drivers. Delays are not expected.
Highway 99 will be closed to traffic in both directions on the night of December 5 to pour a large section of the concrete deck on the north half of the new overpass.
Construction of the new five-lane Steveston Interchange Project is progressing and will require paving and electrical work on Steveston Highway, west of the overpass.
Overnight work is scheduled to take place nightly between 10 p.m. and 5:30 a.m. beginning on December 1, 2024, until the morning of December 12.
Lane closures will be in place on Steveston Highway, and drivers can expect minor delays.
Due to the ongoing construction of the new five-lane Steveston Interchange Project, changes to the bus stops on Steveston Highway will take place beginning November 25, 2024.
On Wednesday, August 7, an overnight Highway 99 closure is required to move a heavy-lift crane across the highway. Vehicles travelling on Highway 99 will be detoured using the on- and off-ramps at Steveston Highway. The northbound loop ramp from Steveston Highway onto Highway 99 will be closed. Traffic will be rerouted to access the north side on-ramp.
The detour will be in place between 11 p.m. and 4:30 a.m. This overnight closure has been completed.
Following that, beginning August 8 and ending the morning of Saturday August 10, Highway 99 traffic will be reduced to a minimum of one lane in each direction overnight.

Lane reductions will resume beginning the evening of Monday August 12 and finish the morning of Saturday August 17.
