Winter 2014

The project was advertised for private contractor bids December 15, 2014. Bid opening is scheduled for January 14, 2015.

This P-2 Structures Preservation Project paints the Interstate 90 Columbia River Bridge connecting Kittitas and Grant Counties.

Why is WSDOT painting the Vantage Bridge?
Originally built in 1962, the 52-year-old, half-mile long Vantage Bridge is part of the vital I-90 corridor. The bridge carries an average of 14,000 vehicles per day, 26 percent of which are trucks.

The majority of the Vantage Bridge was last painted in 1984. Since then, the protective coating on the bridge has deteriorated, exposing the steel to the weather and elements, which has resulted in rust and corrosion. Painting this bridge will preserve the bridge's structural integrity and protect the steel from future corrosion.

The portion of the truss section below the roadway was last painted in 2002 and is still in serviceable condition. This section will not be repainted under this contract.

The End Result
The steel framework of the bridge will be cleaned and repainted with a protective coating. The project will restore and revitalize this important transportation connection and prolong the life of the bridge.

Project Benefits

  • Preservation: This project helps prevent future corrosion and preserves the bridge's structural integrity.
  • Economic: This project preserves a vital trans-state transportation connection, allowing it to continue handling commuter and heavy freight traffic for years to come.

What is the project timeline?
The project was advertised for private contractor bids December 15, 2014. Bid opening is scheduled for January 14, 2015. The project is scheduled to take about nine months to complete.
