HOV lane construction begins on I-405 in Bothell
The Washington State Department of Transportation (DOT) has announced that work will begin in early April to construct northbound and southbound high-occupancy-vehicle (HOV) lanes on Interstate 405 in Bothell.
Crews are putting up signs in preparation for the construction activity that will add approximately six new HOV lane miles to I-405 between State Route 522 and State Route 527. Work in this three-mile section includes constructing two noise walls, widening four I-405 bridges, constructing a northbound collector-distributor between SR-522 and Beardslee Boulevard, installing communications equipment, ramp meters, and closed-circuit TV cameras, building wetlands near the Sammamish Slough, and installing large detention ponds and tanks for treating surface water runoff.
Traffic impacts will include intermittent single-lane and night-time closures on I-405. Two lanes will remain open during the day. Ramp closures will have signed detours. Crews are allowed to close lanes and ramps between 8 p.m. and 5 a.m. Monday-Friday; 7 p.m. and 10 a.m. Saturday, and 7 p.m. and 5 a.m. Sunday.
