Interstate 5/MLK Jr. Way to Northeast Ravenna pavement repair
General contractor: Guy F. Atkinson Construction
In this design-build project, Atkinson repaired or replaced about 13 miles of deteriorating northbound Interstate 5 concrete pavement through downtown Seattle from Martin Luther King Jr. Way to the Ravenna Boulevard bridge. Work included select panel replacement and full-depth pavement replacement, as well as grinding and replacing asphalt shoulders and ramp paving, upgrading drainage structures, replacing traffic loops, installing permanent pavement striping, and performing diamond grinding of the roadway surface for ride quality. A major portion of the work included the removal and replacement of 57 bridge expansion joints and six bridge approach slabs. Atkinson completed all construction work at night and on weekends to minimize impacts to the community and high-volume traffic (over 120,000 vehicles per day). Through collaboration with WSDOT and Atkinson’s design-build approach, the Atkinson team completed all major work in just seven weekends in one construction season a significant improvement over the conceptual design’s 16 weekends over two seasons.
