SAN ANTONIO (KTSA News) — As part of the SH 151 Expansion project, TxDOT will open a new collector distributor road on northbound Loop 1604 at the SH 151 interchange by 12 p.m. Saturday, Nov. 23.

In order to open the road, the Loop 1604 entrance ramp from westbound SH 151 and the Culebra Rd. exit ramp from northbound Loop 1604 will be permanently closed. The permanent ramp closures will begin at 9 a.m. Thursday, Nov. 21. These closures will allow crews to complete paving and striping operations.

A new temporary entrance ramp to northbound Loop 1604 before Culebra Rd. will also open by 12 p.m. Saturday, Nov. 23. The temporary entrance ramp will be in place until the new flyover ramp opens connecting westbound SH 151 to northbound Loop 1604 by summer 2025.
