Best to avoid southbound Highway 99 in Delta on Sunday night (March 20) if you can.
Scheduled shoulder maintenance work is planned between Exit 26 (Highway 17) and Exit 20 (Ladner Trunk Road), a 3.2 kilometre stretch. The right lane will be closed from 7 p.m. until 5 a.m. on Monday (March 21).
Ladner Trunk Road from Highway 17A to Highway 99 would be an alternate route to avoid delays.
