Work to replace I-90 Vantage Bridge deck set to get underway


VANTAGE – After years of patching and filling potholes, crews are now ready to replace the entire surface across the Vantage Bridge along Interstate 90.

The Washington State Department of Transportation and its contractor, Garco Construction, are building an access under the bridge in preparation for the replacement of the existing bridge deck. To minimize longer closures and delays, crews will replace the bridge deck with pre-cast concrete panels.

Beginning Monday, March 11, until after Labor Day, travelers will experience single-lane closures and 10-foot width restrictions in both directions Monday through Friday. Beginning in September, traffic will be restricted to one lane in each direction seven days a week with 9-foot width restrictions with the following exceptions:

Travelers will experience long delays eastbound on Fridays and westbound on Sundays during the summer travel months and are encouraged to choose alternate routes.

Traffic will also be restored to two lanes in each direction for winter from November through April.

The Vantage Bridge was built in 1962. The last time the historic span across the Columbia River received a major overhaul was in 1982. Construction for this project will take approximately three years, with completion anticipated in fall 2027.
