An inspector was called out to examine a Thruway overpass in Spring Valley after the bridge was struck by a truck Saturday evening, State Police said.

A flatbed truck carrying a dump truck struck an abutment on the Hungry Hollow Bridge a few minutes after 6 p.m. The accident knocked pieces of the dump truck onto the southbound lanes of the New York State Thruway, near mile marker 24, police said.

Southbound traffic was reduced to one lane as police worked to clear the scene Saturday night. The driver of the truck wasn't ticketed, but police said they were still looking into the crash to determine whether the truck should have been on the Thruway with the load it was carrying.

An engineer from the New York State Thruway Authority was called in after the accident to inspect the bridge. Results of the inspection weren't immediately available, but police said there was no visible structural damage to the span, which stretches 170 feet across the highway.

The bridge connects Hungry Hollow Road above the Thruway. It was built in 1955. The last routine inspection, dated July 2008, described the bridge's structural condition as "somewhat better than minimum adequacy" and recommended more than $2.7 million in repairs.
