Questions about Project Overview
What are the goals of the 635 East Project?
I-635 East originally opened in 1969 and was designed to accommodate 180,000 cars per day. By 2020, the average daily traffic on 635 East is expected to reach 230,000. This increase in traffic has led to the roadway’s top 30 ranking on Texas’ most congested roadways list. The Texas Transportation Commission has designated the 635 East Project as part of the statewide Texas Clear Lanes initiative, organized to address the most congested areas in the state.
The 635 East Project is designed to relieve congestion, provide local connectivity and improve safety.
Who is the project team involved in building the 635 East Project?
TxDOT owns and manages the project. Pegasus Link Constructors is the design-build contractor.
When will construction begin and end?
Construction began in the spring of 2020. Construction will last through the end of 2024.
How much will it cost to build the project and how is it being funded?
The project will cost $1.7 billion to build. The project is partially funded through TxDOT’s Texas Clear Lanes initiative, which prioritizes voter-approved funding based on needed congestion relief projects in Texas’ metropolitan areas. For more information, visit www.texasclearlanes.com.
What improvements will be made?
Drivers can expect the following improvements:
- One additional lane in each direction along I-635 between US 75 and I-30
- Continuous frontage roads consisting of two to three lanes in each direction along I-635 between US 75 and I-30
- Reconstruction of the I-635/I-30 interchange
- New aesthetic bridge at the Skillman Street/Audelia Road intersection
Questions about Construction and Lane Closures
Will construction be performed in a sequence?
Construction will be performed along the entire corridor simultaneously. The construction sequence that PLC will use for the 635 East Project will be an “outside-in” approach. This prioritizes the new frontage roads (on the outside) prior to the reconstruction of the mainlanes.
Construction will be performed 24 hours a day, seven days a week. However, construction requiring mainlane closures will be performed during the overnight hours and on weekends when traffic is lighter.
What closures can I expect?
Construction will be performed in all hours of the day. However, major lane closures will be performed during the overnight hours when traffic is light.
During the construction phase, the TEXpress lanes will be closed but all four general purpose lanes will be maintained during peak travel periods.
What kind of coordination is needed for a roadway construction project of this size?
Hundreds of people are expected to be working on or along the 635 East project, especially at the peak of construction. Additionally, a project of this size will also require third-party coordination from many different entities including: Dallas County, cities of Dallas, Garland and Mesquite, utility companies, Dallas Area Rapid Transit and KSC Railway Co., area businesses, area residents, community organizations.
What is the construction progress of the sound barriers along the 635 East Project?
The soundwalls were completed in early 2020, prior to the start of major construction activities.
What do I do if I am in an accident, or my vehicle breaks down along the Project?
Get to a safe place and call 9-1-1.
Questions about the project’s TEXpress Lanes
What will happen to the existing I-635 East HOV/Express Lanes between US 75 and I-30 during construction?
The one lane of HOV Express (TEXpress) lane in each direction between US 75 and I-30 was officially closed in April 2020 and will remain closed during construction. When the project is complete, one managed toll lane in each direction will reopen. The existing delineators will be removed and replaced with a concrete barrier, separating the newly reconstructed TEXpress Lane from the mainlanes.
