TxDOT Proposes SH 21 West Madison County Widening
AUSTIN, TX The proposed SH 21/US 190 West Madison County Widening Project would increase capacity from a two-lane undivided roadway to a four-lane divided roadway. The project area extends from 0.8 miles east of the Navasota River for approximately 20 miles to North Wilson Street in Madisonville. The project would be constructed in segments.
This project is part of an overall SH 21 / U.S. 190 corridor study from SH 6 in Bryan to Madisonville. To date, corridor improvements have been completed from SH 6 in Bryan to just east of the Navasota River. An interim passing lane project is being developed and will be constructed through Madison County.
The proposed widening project would require additional right of way and displacements.
SH 21, within the western half of Madison County, is a portion of the U.S. 190 transportation corridor. U.S. 190 is part of the National Highway System and serves as a freight and military route. Proposed improvements include:
Straightening sharp curves in the roadway
Adding two lanes (for a total of two lanes in each direction)
Adding 10-foot outside and four-foot inside shoulders
Separating opposing traffic with a divided grass median
Providing crossover access
The project is expected to improve safety and mobility by accommodating increasing traffic flow with additional travel lanes and by separating opposing directions of traffic with a median.
