West Harrison Street lane closures for pedestrian improvements in Aug and Sept

People driving, walking and riding bikes can expect construction impacts on West Harrison Street, starting as soon as Aug. 3. The pedestrian safety improvements project on West Harrison Street will involve the intersections at First Avenue West and Second Avenue West. Work will occur from 7 a.m. to 5 p.m. on weekdays and is anticipated to take approximately six weeks to complete, depending on weather.

The north side of the intersection of Second Avenue West and West Harrison Street, and the south side of the intersection of First Avenue West and West Harrison Street, will be completely closed to traffic as soon as Aug. 3. These restrictions will remain in place 24-hours a day and are anticipated to last for three weeks. The second phase of construction will require closing the south side of the intersection at Second Avenue West and West Harrison Street and the north side of the First Avenue West and West Harrison Street intersection. These closures will also be in place 24-hours a day for three weeks. (Please see attached construction map.)

In addition, during project work hours, crews will reduce West Harrison Street to one lane between Queen Anne Avenue North and Third Avenue West and a traffic flagger will maintain two-way traffic. Drivers can also expect on-street parking restrictions in this area.

The Seattle Department of Transportation encourages southbound traffic to use Queen Anne Avenue North and northbound traffic to use Third Avenue West. People walking and riding bikes will be routed around the closure. Please follow detour signage.

The pedestrian safety improvements where First Avenue West and Second Avenue West intersect West Harrison Street will include construction of new curb extensions, to shorten the length of pedestrian crossings and improve visibility between pedestrians and motorists, and upgrades to curb ramps to comply with current Americans with Disabilities Act (ADA) standards. This project is funded by the Bridging the Gap transportation levy, through the Neighborhood Street Fund Program.
