The Dalles – The Oregon Department of Transportation has awarded a contract to Stellar J. Construction Company to replace and retrofit eight bridges on US 97.
The project will replace the existing US 97 Spanish Hollow Creek Bridge, located a half-mile south of Biggs Junction, and the Trout Creek Bridge, 17 miles north of Madras, to new seismically resilient bridges. Additional work will be done to seismically retrofit six other bridges over Spanish Hollow Creek near Biggs junction. Crews will also extend the southbound acceleration lane of US 97 from the US 30/US 97 intersection at the Biggs Jct. Interchange to match into the US 97 climbing lane a half mile south of the interchange.
The $15 million dollar project is essential to assist with traffic mobility in the case of a major seismic event. Crews have begun preliminary work to prepare for the bridge replacements. Motorists can expect to see temporary signals at both Spanish Hollow & Trout Creek bridges which will reduce traffic down to one lane. Oregon State Police will be enforcing the work zone for the duration of the project. The project is scheduled to be complete by fall 2019.
