Lane reductions on one block of First Avenue in downtown Seattle next week
Crews installing underground monitors along the State Route 99 tunnel route next week will reduce southbound First Avenue to one lane between Union and University streets.
Parking will be closed on the west side of First Avenue Monday and Tuesday and on the east side of the street Wednesday through Saturday. Signs will direct drivers around the closures. The work will not affect access to parking lots, buildings and driveways.
- Monday, Jan. 28 – Saturday, Feb. 2 – Southbound First Avenue between Union and University streets reduced to one lane 7 a.m. Monday to 10 p.m. Saturday. Two northbound First Avenue travel lanes will be open at all times.
- Monday, Jan. 28 – Tuesday, Jan. 29 – Parking on the west side of the street will be closed from 7 a.m. Monday to 10 p.m. Tuesday.
- Tuesday, Jan. 29 – Saturday, Feb. 2 – Parking on the east side of the street will be closed from 7 a.m. Tuesday to 10 p.m. Saturday.
The underground monitors are part of a comprehensive program to help mitigate ground movement and protect structures during tunneling, which is scheduled to begin in the summer. Drivers should expect similar lane closures on First Avenue between University and Virginia streets through February.
