TOPEKA, Kan. (AP) — A pedestrian bridge at a Topeka race track has collapsed as a dump truck loaded with dirt crossed it.

The Topeka Capital-Journal reports that the driver wasn’t believed to be injured after the city-owned truck fell onto the grassy slopes and landed on its wheels. City spokeswoman Aly Van Dyke says the bridge is primarily used for foot traffic and vehicles such as golf carts.

The city is looking into what happened. The bridge collapse comes as many workers were at the track preparing for this weekends’ NHRA drag racing. Plans are being made for a contractor to evaluate the damaged bridge and another smaller bridge at the track for safety.
