Project overview
This project will rehabilitate roughly two miles in each direction of State Route 99 from the SR 516 intersection in Kent to South 200th Street in SeaTac. Crews will grind and inlay new hot mix asphalt giving the roadway a smoother surface and preserving it for years to come. Pedestrian curb ramps will also be evaluated and updated as necessary to meet the Americans with Disabilities Act and current accessibility standards.
What to expect
During construction, crews will grind the road surface and inlay new hot mix asphalt. Work will primarily be at night. Throughout the project, travelers can expect directional double-lane closures along SR 99. Single-lane closures at some locations for curb ramp construction is possible. Directional closures will be in place during intersection paving.
This project will pave and make ADA improvements in both directions of State Route 99 from SR 516 to South 200th Street.
