Crews also continue construction on the north side of Mercer Street between Fifth Avenue North and Dexter Avenue North and the east side of SR 99 between Valley and Harrison streets.

Activities this week include:

  • Begin intermittent daytime single lane closures on the I-5 on-ramps at Mercer Street.  A single lane on eastbound Mercer Street will be closed between Boren Avenue North and the I-5 on-ramps at Mercer Street while crews perform curb barrier installation and landscaping work along the ramps. Work hours will be from 9 a.m. to 3 p.m. for approximately two weeks. Three lanes of Mercer Street and the I-5 on-ramps will remain open during this work.
