(Seguin) — It’s been four years since the plans to widen State Highway 123 were first brought to the community for public input. Now, the long-awaited project is finally coming to fruition.
The Texas Department of Transportation is preparing to begin work on widening SH 123 between Cordova Road and Interstate 10, a corridor that officials say has seen aggressive residential and commercial growth in recent years.
The project was first introduced to the public during input meetings back in March 2022.
Tanya Brown, public information officer for TxDOT’s San Antonio District, says the plan is to widen the roadway to better handle increasing traffic volumes and future development.
“TxDOT is planning to widen State Highway 123 in Seguin. The project will expand the roadway from two lanes to four lanes. So, the planned improvements will take place on State Highway 123 between Cordova Road and I-10, commonly referred to State Highway 123 Bypass North,” said Brown.
Brown says the work which will include two 12-foot-wide lanes in each direction is aimed at addressing both current congestion and future growth along one of Seguin’s busiest routes.
“The project is needed to improve safety and mobility along the corridor. Traffic volumes in the area continue to increase, and the widening will help accommodate that growth. In addition to adding lanes, the project is going to also include raised medians and turn lanes, which are designed to reduce conflicts, improve traffic flow, and better support continued development in the area,” said Brown.
Brown says residents should expect construction to begin in the next few months.
“The timeline construction could begin as early as late summer or early fall. The overall timeline will depend on final preparation and construction phasing,” said Brown.
While TxDOT has not yet announced where crews will begin along the corridor, Brown expects that information to be shared as soon as possible.
“At this time, we haven’t announced a specific direction on where construction will begin, but that information will be shared once construction phasing is finalized,” said Brown.
The project includes a price tag of $51.3 million. Although additional right-of-way will be needed, TxDOT says no homes or businesses are expected to be displaced.
