TxDOT proposes $158 million SH 121 widening project

The Texas Department of Transportation held a public hearing Tuesday night for improvements along SH 121. TxDOT is proposing to widen SH 121 from two lanes to a four-lane divided highway from the Collin County Outer Loop to north of CR 635. The project is anticipated to begin in 2026 and be complete by 2029, according to a news release from TxDOT.

The proposed 9.52-mile widening project is estimated to cost approximately $158 million. Improvements would also include 10-foot wide outside shoulders which would serve as bicycle accommodations, according to TxDOT.

The proposed project would require approximately 165.075 acres of right of way and 2.417 acres of permanent easement potentially displacing four residences, one commercial building and one barn.

The purpose of the project is to improve mobility, decrease traffic congestion, accommodate population growth and enhance safety for the traveling public, according to TxDOT officials.

Funding commitments for the project have not been determined.
