SAN ANTONIO -- Drivers on southbound U.S. Highway 281 had to deal with debris on the road Tuesday morning.
Several vehicles were seen pulling over and changing flat tires near Jones Maltsberger and Basse Road around 6:45 a.m.
Some of the southbound lanes had to be closed while crews worked to clear up the debris.
News 4 WOAI was told Texas Department of Transportation had "bridge joint work overnight on US 281 SB that failed." A spokesperson for TxDOT says "The bridge joint material didn't adhere to and popped out and apparently broke off into chunks as traffic drove over the highway."
It's not known if this is what caused the flat tire problem.
