On Sept. 4, two additional southbound lanes from Oak Run Parkway to San Antonio Street will open for drivers beginning at 9 a.m., according to a TxDOT news release.

In addition, southbound access from Loop 337 to Landa Street will open for drivers at the same time, the release said.

All drivers accessing Loop 337 from Ridge Hill Drive will have to head northbound. Drivers wishing to head south on Loop 337 from Ridge Hill Drive can use a turnaround at the interchange with SH 46, according to TxDOT.
