I-5/NB MLK Jr Way to NE Ravenna Br - Pavement Repair
Atkinson is performing repair or replace work on the deteriorating I-5 northbound concrete pavement through downtown Seattle from Martin Luther King Jr Way to the south to Ravenna Blvd. Bridge to the north—approximately 12.5 miles. Work includes select panel replacement and full-depth pavement replacement with Portland Cement Concrete Pavement (PCCP), as well as grinding and replacing asphalt shoulders, upgrading drainage structures, replacing traffic loops, installing permanent pavement striping, and performing diamond grinding of the roadway surface to ensure ride quality. A major portion of the work includes the removal and replacement of 36 mainline and 34 ramp bridge expansion joints and six bridge approach slabs.
Atkinson must complete all work at night or on weekends in order to minimize impacts to traffic as the project could affect more than 120,000 vehicles per day. This is critically important to accommodate residents, businesses, and events near Seattle—a city already disrupted by unprecedented construction activity. Atkinson committed to complete all work using only ten weekend lane closures and one weekend full closure of northbound I-5—with weekend preparatory work performed at night. The dates for each closure will be selected in collaboration with WSDOT, the City of Seattle, and major sports teams (e.g., Seattle Mariners, Seattle Sounders, and Seattle Seahawks) to avoid impacts to city events (e.g., Seafair, Seattle Center, Emerald City Marathon, Safeco Field, and Century Link Field non-sporting events). Atkinson is also coordinating with local educational institutions to facilitate graduation ceremonies (e.g., University of Washington, Seattle University, and Seattle Pacific University).
