The Seattle Department of Transportation (SDOT) announces the I-5 on- and off-ramps at Mercer Street will be closed throughout the weekend of June 7 -10, weather permitting, as part of the Mercer Corridor Project.
The ramps will be closed from 11 p.m. on Friday until 5 a.m. on Monday. During the closure, crews will install new drainage facilities, repair the off-ramp roadway base, repave and stripe the off-ramp, install guardrails on both ramps, and continue the installation of the sign bridges across the ramps. Please note that this work is dependent on weather and is subject to cancellation.
Due to multiple events in the Seattle area during this weekend, travelers are encouraged to plan ahead and expect delays. Detour routes will be signed on roadways and may be heavily used, particularly Denny Way both eastbound and westbound. Detour route maps are available on the project website at: www.seattle.gov/transportation/mercercorridor.htm.
During these closures, the I-5 on-ramp at University Street will also be closed to provide more efficient traffic flow around the closed Mercer Street exit lane. Fairview Avenue North will be restricted between Republican Street and Eastlake Avenue East to freight and local access, and Mercer Street will be closed to through traffic between Westlake Avenue North and Fairview Avenue North.
Travelers are encouraged to carpool and use alternate modes of transportation. Transit information can be found at:
