I-35E Phase II Dallas County

progressed

Procurement for a Phase 2 of the I-35E project in Dallas County is under way. In 1998, TxDOT began a comprehensive review and planning study of the I-35E corridor in Dallas and Denton counties. For the next 13 years, TxDOT and communities and stakeholders refined the designs and upgrades for this corridor. In 2011 and 2012, TxDOT received environmental clearance for the $4.8 billion infrastructure project. Also, $1 billion in funding was identified for an initial phase of the project with most coming from SH 121 regional toll revenue funds dedicated to Denton County. In accordance with state law, TxDOT and corridor stakeholders held seven public meetings to determine the method and scope of the initial phase (Phase 1) as well as lay the groundwork for future phases to complete the remaining elements of the ultimate reconstruction of the corridor. Phase 1 of the I-35E project began in 2013 and was completed in 2018 known as the I-35E Managed Lanes Project. The project added two-lane reversible tolled managed lanes to the entire 28-mile corridor and additional general-purpose lane capacity in Denton County. It also included mainlane, frontage road, and interchange improvements. The I-35E Phase 2 project covers the southern segment of I-35E in Dallas County from I-635 to the Denton County line and is currently being progressed through a design-build project delivery. The Phase 2 project reconstructs and widens the mainlanes from six to eight lanes. It also reconstructs the two existing, grandfathered reversible tolled managed lanes, frontage roads and improves several intersections. This is a Texas Clear Lanes project. Texas Clear Lanes is a statewide strategic plan to provide congestion relief through non-tolled roads and is focused on the five largest metro areas in Texas.
