The Texas Department of Transportation 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 I-10 East from just west of I-410 to the Bexar/Guadalupe County line. The projects include adding and reconstructing mainlanes, improving overpasses and interchanges, reconstructing/reconfiguring ramps and shifting from two-way to one-way frontage road access, and are part of a 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 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.

Current Construction Projects

TxDOT has initiated construction of I-10 East improvements from I-410 to Graytown Road under two separate but overlapping projects:

• I-10 East between Foster Road and Graytown Road - various safety and mobility improvements started in 2016.
• I-10 East from I-410 to Loop 1604 - construction of mainlane improvements along an approximately 6.7-mile section of I-10 started in Fall 2018.

Ongoing Improvements

The following specific improvements are being constructed under these projects:

•  I-10 frontage road conversion from Foster Road to Graytown Road:
  • ­   Conversion of two-way frontage roads to one-way operation
  • ­   Anticipated completion: 2020
• I-10 ramp improvements between Foster Road and Graytown Road:
  •   Relocation and reconfiguration of entrance and exit ramps (including "ramp reversals") to improve safety and mobility and merging between the mainlanes and frontage roads
  • Anticipated completition: 2020
• Woodlake Parkway overpass:
  • ­   Addition of a new bridge over I-10 at Woodlake Parkway
  • ­   Anticipated completion: early 2019
• Intersection improvements at Foster Road, FM 1516 and Loop 1604
  • ­   Rebuilding intersections to optimize traffic flow and mobility
  • ­   Anticipated completion: early 2020
• I-10 Mainlane reconstruction and widening from I-410 to Loop 1604:
  • ­   Reconstruction of existing eastbound and westbound mainlanes
  • ­   Addition of one general purpose lane in each direction, which will widen the freeway from four to six lanes.
  • ­   Anticipated completion: 2022

Upcoming Construction Projects 

The following construction projects are anticipated to begin in the next year:

• I-10 East mainlane reconstruction and widening from Loop 1604 to Graytown Road:
  • ­    Reconstruction of existing eastbound and westbound mainlanes
  • ­    Addition of one general purpose lane in each direction, which will widen the freeway from four to six lanes.
  • ­    New “reversed” ramps
  • ­    Anticipated start: Late 2019
• Loop 1604 widening at I-10 East:
  •    Addition of one general purpose lane in each direction from I-10 south to Martinez Creek, which will widen the road from two to four lanes
  • ­ Anticipated start: 2019

Traffic Benefits

Once complete, these improvements 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 to Traffic

Throughout construction of these improvements, motorists will encounter 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 occur 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.

Traffic Updates

Permanent and temporary digital message boards placed along the route will alert motorists in real time to lane closures, traffic congestion, and construction activity.
