TxDOT outlines multi‑year 146 expansion at Red Bluff; residents push for new noise study

TxDOT engineers at a Seabrook town hall on Oct. 12 outlined ongoing work to widen State Highway 146 from Red Bluff to Spencer and described plans and timelines for the Red Bluff overpass and adjacent feeder roads. The agency said the overpass work is expected to be structurally complete in June or July 2025 and that the larger project — about 5.8 miles — began in the first quarter of 2022 and is projected to finish in the third quarter of 2028.

Why it matters: The work will change local access patterns and has prompted persistent concerns from neighborhoods such as Lake Cove about traffic noise and long detours while ramps are reconfigured.

TxDOT’s Southeast area engineers said the project includes widening multiple overpasses, full structural replacement of several bridges and constructing two one‑direction frontage roads with a shared pedestrian and bike path. "Widening of the overpasses is gonna be over the Red Bluff, Shore Acre Boulevard and ... the structure itself will be completed in a few months," said Jamal Elahi, Southeast Harris Area Engineer, TxDOT. He said the northbound feeder road work was about 75% complete at the time of the meeting and that the existing southbound feeder currently operates as a two‑way and will remain so for roughly two more years before becoming a dedicated southbound roadway.

TxDOT also described changes to ramps at Red Bluff: the existing southbound exit to Red Bluff will be shifted north near Gion in the later stages of the project; a northbound on‑ramp from Red Bluff will remain open until the northbound feeder is finished.

Old Highway 146 intersection: City and TxDOT staff said intersection reconstruction at Old Highway 146 (the Red Bluff/Old 146 intersection) remains planned but is delayed while utility relocations are completed and while TxDOT evaluates funding paths. TxDOT said options include a change order to the current CSJ (control‑section job) or packaging the work into a new CSJ depending on contractor pricing and funding availability. "If we close the whole thing, it gets done fairly quickly. But if it becomes more of an access issue, then we can certainly look into building it half and half," a TxDOT project manager said.

Noise and sound‑wall debate: Multiple residents urged TxDOT and the city to order a new noise study, saying a 2013 study predated major changes — including higher posted speeds and completed overpasses — and no longer reflects current conditions. "We need another sound study," said Ivy Buskey of Lake Cove HOA, noting about 507 homes there. Several other residents described loud overnight and early‑morning traffic noise.

TxDOT staff said the environmental and sound analyses for this project were completed in the project’s early planning phase and that, according to their current environmental review, additional sound walls were not warranted for large stretches of the corridor. "The sound study did not warrant that," said David Ballard, TxDOT Southeast Harris area office. TxDOT representatives said staff had exchanged emails with citizens and with the agency’s environmental section and would pass community requests up the chain but that additional studies or mitigation above what is contained in the project would have to be escalated for separate funding or added project scope.

Community requests and city coordination: City staff acknowledged the public’s frustration with communication and said they had asked TxDOT to review residents’ concerns. "If you send us that request we will then respond back to you directly," a TxDOT representative said when asked how citizens could push for a new study. Several residents asked the city and TxDOT to press regional decisionmakers and the Houston‑Galveston Area Council for expedited funding and to revisit mitigation such as sound walls. No formal commitments to a new, post‑construction noise study were made during the meeting.

What remains unresolved: Project timing for the Old 146 intersection depends on contractor pricing and funding decisions; the exact duration of some ramp closures was estimated in years rather than months; and TxDOT maintained that the current environmental record does not support additional corridor‑wide sound walls without new analyses or added scope.

Next steps: TxDOT said it will continue construction on the overpass area and will return pricing for the Old 146 work; the city said it would pass community concerns to agency leadership and look for higher‑level escalation if necessary.
