The driver of a Walmart semi truck misread the height restriction on a rail overpass south of Salem, wedging the trailer under the tracks Monday morning.
The crash closed South River Road until a tow truck could remove the wreckage of the 9 a.m. wreck, according to the Marion County sheriff's office.
The driver, Glenn Bickford, 63, of Coos Bay told police that he had left a Walmart in South Salem and used a GPS guide to get him to a store in Monmouth. It told him the most direct route, which took him along South River Road towards Independence.
After the mishap, Bickford stayed at the scene and cooperated with deputies. He thought the rail overpass sign read 13 feet nine inches but it actually read 12 feet nine inches. His trailer was 13 feet three inches tall.
