Resurfacing work on several NW Washington highways
Published:2018-03-13 Roads
Resurfacing work on several NW Washington highways Crews will spread a new thin layer of pavement on nearly 40 miles of road, on seven highways in four counties between spring and fall 2018. This new surface will help preserve these highways, but also means weeks of lane closures and delays for drivers and people riding bicycles while it is completed. Daytime lane closures Work hours vary on depending on the highway, but travelers should expect delays from 5 a.m. to 5 p.m., Monday through Friday. Traffic will alternate through the work zones. Depending on traffic volumes, drivers should factor extra time into their trips. Stages of work The second stage will begin in July when temperatures are hotter. The crews place a mixture of oil, sand and gravel mixture on the road to form the new asphalt. They must wait for it to dry before reopening lanes to traffic to prevent it from spraying up on vehicles. Where possible, crews only apply this mix between the white fog lines, to leave a smoother surface on shoulders for cyclists. “The mixture needs hotter temperatures to cure properly,” said Project Engineer Shane Spahr. “Even during the summer, nighttime temperatures are too low for this type of work. While we want our work to cause as few headaches as possible for travelers, with this project, we need the daytime summer temperatures to help set the materials, which means commuters on these highways will need to plan for long daytime delays.” Travelers should allow an extra 45 minutes in travel time during the second stage of work.
