It carries State Route 155 across the Columbia River immediately below Grand Coulee Dam, near the city of Grand Coulee, Washington.
The bridge is supported by two concrete piers, about 150 feet (46 m) high.
During construction, one of the piers began to tilt, probably due to fine glacial material under the gravel.
