Record confirms

TxDOT says it is expanding approximately 20 miles of I-35 from N. Walters Street to FM 1103 in Bexar, Comal and Guadalupe counties, including elevated structures with general-purpose and HOV lanes.

Why this matters

I-35 NEX is one of the clearest examples of infrastructure chasing growth along the San Antonio–Austin corridor.

Watch next

Segment schedules, ramp closures, construction notices and adjacent municipal development.

Public question

Will frontage-road access, construction impacts, drainage and safety improvements match the pace of regional development?

Possible local levers

Cities along the corridor should coordinate land-use approvals with TxDOT access, drainage and safety constraints.

Evidence boundary
This confirms a policy, planning, or docket process. It does not by itself establish a site-specific approval or project commitment.

Community impact lens

Watch traffic volumes, freight routes, crashes, access management, emergency response, improvement timing, and whether project growth arrives before road capacity.
