Project Description: 

The IH 635 Managed Lanes Project will relieve congestion north of Dallas, Texas on 13 miles of IH 635 (LBJ Freeway) from just west of I-35E (near Luna Road) to just east of US 75 (near Greenville Ave.), and south on I-35E from I-635 to Loop 12. The project will involve:

  • Reconstruction of the main lanes and frontage roads along IH 635
  • Addition of six managed lanes (mostly subsurface) along IH 635 from I-35E to US 75 and four managed lanes west and east of that stretch
  • Addition of six elevated managed lanes along I-35E from Loop 12 to the I-35E/IH 635 interchange

The project is being built under a public-private partnership (P3)/CDA between TxDOT and LBJ Infrastructure Group, which will operate and maintain the facility for 52 years. Construction is expected to take five years. The managed lanes will be dynamically priced after six months of an introductory fixed-price schedule. HOV2+ users will receive a 50 percent discount during peak operating periods. Tolls will be collected by the North Texas Tollway Authority.

The IH 635 Managed Lanes Project is designed to relieve congestion and provide capacity for the area’s growing demand for transportation infrastructure. By 2020, Dallas County is expected to see traffic volumes of 420,000 average vehicles per day, an increase of approximately 65% above 2007 volumes, when the project application was submitted. The use of TIFIA financing and P3 structuring allowed for the delivery of these mobility benefits approximately 19 years faster than more conventional financing methods would have allowed.
