Road work on Loop 1604 at Blanco Road shakes up neighbors

Overnight “controlled blasts” are part of major project

SAN ANTONIO – Now that the next phase of the Loop 1604 construction project is underway, some neighbors report being jolted awake by the road work. Crews are excavating and using controlled explosions to clear material at the Blanco Road intersection.

“Our experience was that the blasting was very alarming. We heard a very loud noise and then our house vibrated. The walls shook, the windows vibrated and the wood in the house creaked,” said David Black, who lives south of Loop 1604. “Since we are not experts, we weren’t really sure what to make of it and were concerned. The blasts were about 30 minutes to 1 hour apart so there was no sleeping for us between 11:30 (p.m.) and 2:30 (a.m.) or so.”

The road work is part of a massive expansion of the highway from a four-lane highway to a ten-lane highway. TxDOT projects that once completed, the overall project will reduce travel times in the Loop 1604 corridor by 76%.

The periodic overnight closures of the intersection are scheduled from 11 p.m. to 5 a.m. this week. The section of the project between Highway 281 and I-10 is expected to be completed in 2025.
