Six-month ramp closure in Tacoma to start Monday

Crews plan to close the ramp from northbound state Route 7 to southbound Interstate 5 for six months, starting Monday.

The closure will let workers use the ramp as a construction zone to build supports for a new bridge, and to install additional drainage, according to the state Department of Transportation.

The work is part of a project to rebuild Pacific Avenue and McKinley Way bridges that span I-5, after which new carpool lanes will open. State Route 7 at that point is a short spur that begins at East 38th Street and crosses under the East 34th Street bridge to join the freeway.

Crews will close the ramp at 10 p.m. Monday and expect to reopen it in May.

The southbound I-5 exit to state Route 7 and the A street onramp to northbound I-705 will continue to be closed.

Other lane and ramp closures will affect I-5 in Tacoma next week:

Monday through Thursday, they’ll close up to two lanes of southbound I-5 between M Street and Portland Avenue at 8 p.m., and will reopen all lanes at 6 a.m. the next day.

They’ll close again Dec. 6 and Dec. 7 at 9 p.m., reopening at 6 the next morning. They’ll close the left lane of northbound I-5 at 11 p.m. Dec. 5, and will reopen it at 7 a.m. Dec. 6.

The northbound I-5 exit to state Route 7 will close Monday and Tuesday at 11 p.m., and will reopen at 4 a.m. the next day.

The southbound I-705 onramp to northbound I-5 will close Monday through Wednesday at 11 p.m., and reopen at 4 a.m. the next day.

Crews will shut down the southbound I-5 exit to City Center at 10 p.m. Wednesday, and will reopen it 6 a.m. Thursday.

The Pacific Avenue onramp to southbound I-5 will close 10 p.m. Thursday, and the City Center onramp to southbound I-5 will close at 11 p.m. Both will reopen 6 a.m. Dec. 5.
