LBJ Express / IH 635 Managed Lanes

Close

The LBJ Express (formerly the IH 635 Managed Lanes Project) relieves congestion north of Dallas on 13 miles of I-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 involved: Reconstruction of the main lanes and frontage roads along I-635 Addition of six managed lanes (mostly subsurface) along I-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/I-635 interchange The project is being built under a public-private partnership (Comprehensive Development Agreement [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 are dynamically priced following a six-month introductory fixed-price schedule. HOV2+ users receive a 50 percent discount during peak operating periods. Tolls are collected by the North Texas Tollway Authority.
