I-5 - NB S 260th St to Duwamish River Br - Concrete Pavement Rehab and ADA - Driver expectations

Upcoming weekend-long lane reductions: Drivers should plan for two weekends of lane reductions on northbound I-5 at the Duwamish River Bridge for expansion joint work. We will schedule those dates after the new SR 99 tunnel opens in early February. ​

Nighttime lane reductions: Work began in April 2017 with crews using overnight lane reductions, mostly on weeknights, to replace concrete panels, grind and pave. Nighttime lane reductions will take place throughout the two years of the project. 

* Northbound I-5 will remain open at all times, although the number of lanes may be severely limited.
