Plan Additional Travel Time for I-5 Construction in Washington

Late night and early morning drivers who travel on Interstate 5 in Lacey are encouraged to plan additional time to their trips. Starting as soon as Monday, June 18, contractor crews working for the Washington State Department of Transportation will begin a project to replace aging and worn I-5 bridge expansion joints at Martin Way.

Night work

  • Night single-lane closures will begin as early as 9 p.m. in both directions of I-5.
  • All lanes will reopen no later than 5:30 a.m. weekdays.
  • All work is weather-dependent.
  • The project is expected to be complete by mid-summer.

Expansion joints are a critical component for bridges. They allow sections of a bridge to expand and contract with changing temperatures and traffic loads. The expansion joints on these bridges are decades old.

This work is similar to a previous WSDOT project that replaced aging bridge expansion joints at Pacific Avenue in Olympia last summer.
