Lane reductions on one block of First Avenue in downtown Seattle week of Feb. 4

Posted on Feb 1 2013 3:42 PM

Crews installing underground monitors along the State Route 99 tunnel route next week will reduce southbound First Avenue to one lane between Pine and Pike streets.

Crews will also close street parking on both sides of First Avenue. Signs will direct drivers around the closures. The work will not affect access to parking lots, buildings or driveways.

Travel impacts

  • Monday, Feb. 4 – Friday, Feb. 8: Southbound First Avenue between Pine and Pike streets will be reduced to one lane from 7 a.m. Monday to 10 p.m. Friday. Two northbound First Avenue travel lanes will be open at all times.

 

Parking impacts

  • Monday, Feb. 4 – Friday, Feb. 8:  Street parking on the both sides of First Avenue between Pine and Pike will be closed from 7 a.m. Monday to 10 p.m. Friday.

 

These closures allow crews installing underground monitors along the SR 99 tunnel route to continue progressing north on First Avenue. 

The underground monitors are part of a comprehensive program to help mitigate ground movement and protect structures during tunneling, which is scheduled to begin this summer.

Drivers should expect similar lane closures on First Avenue between University and Virginia streets through February.
