I-5 North Repaving Project Set to Begin
For the first time since it was constructed in the 1960s, Interstate 5 Northbound will undergo repaving beginning this week. The project will span 22 miles between Kent and Ravenna Boulevard in Northeast Seattle. The Washington State Department of Transportation (WSDOT) expects this to last through 2019.
The existing concrete pavement along this section of I-5 North is long overdue for replacement, as it was built to last for only 25 years. The southbound side of I-5 is currently on the tail end of a similar 13-mile repaving project between Tukwila and Federal Way.
The I-5 repaving project will start on the south end of the 22-mile stretch. Crews will start by using machinery to cover the current concrete with fresh asphalt, while other areas of the highway will be replaced entirely with asphalt (rather than covered). The project will also involve replacing joints that attach the roadway to adjacent bridges.
WSDOT is planning for 10 weekend lane closures along this stretch of I-5 North. 2 lanes will remain open during each closure, but heavier than usual traffic is expected. Initial work will be completed at night when possible, but most of the work is expected to be completed throughout this summer and the next.
The first phase of the project will cost approximately $31 million. The second phase, which will cover the area between Rainier Beach and Ravenna and will begin later in 2017, is expected to cost $36 million. This portion will also include additional repairs and replacements to several sections of elevated roads, plus adjacent on-ramp and off-ramp repaving.
