A portion of River Road was shut down after a street sweeper truck caught fire Thursday morning.
Both directions of River Road were closed between Delhi Pike and State Avenue. The westbound 6th Street Viaduct was also closed because semi trucks are stuck and unable to turn around.
The incident happened at about 4 a.m. It took several hours for the road to reopen because diesel fuel was spilled.
Police say the street sweeper didn't realize his truck was on fire until another motorist grabbed his attention and directed him to pull over. The sweeper tried to put the fire out himself, but it was too big.
