Drivers are advised to expect overnight delays on Highway 99 in Delta on Monday, Aug. 10, and Tuesday, Aug. 11, 2026, as crews install new bridge girders for the 78th Street overpass.
Two overnight closures are needed so the work can be completed safely.
Closures will start each evening with single lanes in each direction before progressing to full highway closures one hour later:
- southbound lane closures will start at 7 p.m., followed by a full southbound closure at 8 p.m.
- northbound lane closures will begin at 8 p.m., followed by a full northbound closure at 9 p.m.
The closures will be in effect between the Highway 91 and Highway 17 interchanges. Highway 99 will reopen in both directions by 5 a.m. each morning.
During the closures, traffic will be detoured via Highway 91 and Highway 17. All vehicles, including commercial traffic, will be required to exit Highway 99 at Exit 16 for northbound traffic and Exit 26 for southbound traffic.
Drivers should plan for additional travel time and expect minor delays on Highway 99, Ladner Trunk Road, Highway 91 and surrounding roads during the work.
Travellers are reminded to obey posted signage, follow directions from traffic-control personnel and use caution when travelling through construction zones.
