TxDOT is committed to improving mobility and increasing safety for motorists using the heavily traveled I-10 corridor on San Antonio’s east side.

Multiple improvement projects are currently planned or under construction along overpasses and interchanges. Converting the frontage roads from two-way to one-way access with turnarounds at cross street intersections is also part of the larger plan to improve the entire I-10 corridor between San Antonio and Houston. 

Current and proposed I-10 East projects will address the following issues:

• Increasing capacity to meet the growing traffic demand
• Upgrading the freeway to current federal and TxDOT safety and design standards
• Addressing deteriorating pavement conditions due to heavy traffic use, large truck volumes, and poor soils in the area

I-10 East Construction Projects

In 2016, TxDOT began reconstructing I-10 East from I-410 to the Bexar County line under five separate but overlapping projects. They include:

• I-10 East from Foster Road to Graytown Road – Construction of various safety and mobility improvements. The project began in 2016 and was completed in fall 2020.
• I-10 East from I-410 to Loop 1604 – Construction of mainlane and ramp improvements along an approximately 6.7-mile section of I-10.  The project began in fall 2018 and is expected to be complete by mid-summer 2021.
• I-10 East from Loop 1604 to Pfeil Road – Construction of mainlane, ramp, and frontage road improvements along an approximately 2.8-mile section of I-10. The project began in early 2020 and is expected to be complete in 2024.
• I-10 East from Graytown Road to the Bexar County Line – Construction of mainlane, ramp, and frontage road improvements along an approximately 5-mile section of I-10. The project began in late 2020 and is expected to be complete in 2024.
• I-410/I-10 East Interchange – Construction of two direct connector ramps from northbound I-410 to eastbound I-10 and from westbound I-10 to southbound I-410. The project began in summer 2021 and is expected to be complete in 2024.

Traffic Benefits

The improvements along this section of I-10 will enhance safety and mobility and reduce congestion by:

• Increasing capacity to meet the growing traffic demand
• Upgrading the freeway facility to current federal and TxDOT safety and design standards
• Addressing deteriorating pavement conditions due to heavy traffic use and poor soils in the area
• Reducing potential conflicts between frontage road vehicles and those entering and exiting the mainlanes
• Providing turnarounds to assist with local access following conversion of frontage roads to one-way operation
• Improving intersection operations

Construction Impacts on Traffic

Throughout construction of these improvements, drivers will experience temporary traffic shifts and overnight lane closures on the mainlanes and frontage roads in both directions, as well as temporary daytime and overnight ramp closures. TxDOT will do everything possible to keep two mainlanes open in each direction during peak travel times.

Daytime work is anticipated to take place Mondays through Saturdays, while nighttime work and any necessary lane closures are anticipated to take place between 9 p.m. and 5 a.m., Sunday evenings through Friday mornings. Occasional weekend (Saturday and Sunday) closures for major traffic shifts or bridge construction operations may take place. At times, traffic may be detoured to frontage roads.

Traffic and Construction Updates

The latest information on lane closures, traffic shifts, and overall progress of the projects under construction is provided through:

• Local news media outlets
• The San Antonio District’s Go Ahead! blog, Twitter feed, and Facebook page
• Permanent and temporary digital message signs stationed along the project corridor alerting drivers in real time to lane closures, traffic congestion, and construction activities
• DriveTexas.org

Previous Public Involvement Activities

TxDOT strives to communicate with the public proactively and effectively throughout the project development phase before construction. This includes providing information and gathering feedback on mobility and safety issues that could impact the public by making transportation improvements.

Public involvement activities on the I-10 East corridor include:

• An Open House on July 9, 2015, was held to provide information on the frontage road conversion, ramp reversals, Woodlake Parkway Overpass, and intersection improvements
• A Public Meeting in November 2016 was held to provide information on the mainlane improvements
