TxDOT Seeks Input on the I-35 Capital Express South Project

Contact: Diann Hodges

Phone: (512) 832-7027

Date: Dec. 1, 2020

AUSTIN – The Texas Department of Transportation is hosting a virtual stakeholder meeting to gather input on proposed improvements on I-35 from SH 71/Ben White Boulevard to SH 45 Southeast.

The $300 million improvement project, known as the I-35 Capital Express South project, proposes adding two non-tolled managed lanes in each direction along I-35 from SH 71/Ben White Boulevard to SH 45 Southeast. The project also includes various operational and safety enhancements that would reconstruct bridges, eliminate five mainlane merges and improve east/west connections over or under I-35.

The virtual stakeholder meeting will provide an update on the project design since the last public open house held in October 2019. Design changes include:

  • Elevating managed lanes between SH 71/Ben White Boulevard and Slaughter Lane.
  • Constructing a southbound I-35 intersection bypass lane at Stassney Lane and William Cannon Drive.
  • Adding 2.5 miles of auxiliary lanes for entering and exiting traffic.
  • Constructing braided northbound entrance and exit ramps at Slaughter Lane.
  • Widening the northbound and southbound I-35 frontage roads to three lanes south of Slaughter Lane.

The virtual stakeholder meeting will be made available on beginning Thursday, Dec. 3 through Friday, Dec. 18, 2020. Input on the project can be submitted via online survey, email, voicemail or mail.
