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, reconstructing and relocating ramps, and improving overpasses and interchanges. Converting the frontage roads from two-way to one-way access 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 and poor soils in the area.

Current Construction Projects

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

• I-10 East frontage roads 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.
  
• I-10 East from Loop 1604 to Pfeil Road - construction of mainlanes, bridges, and frontage road improvements along an approximately 2.8-mile section of I-10 started in early 2020.

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: Fall 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: Spring/Summer 2020
• Intersection improvements at Foster Road, FM 1516 and Loop 1604
  • ­Rebuilding intersections to optimize traffic flow and mobility
  • ­Anticipated completion for Foster Road and FM 1516: Fall 2020
  • Anticipated completion for Loop 1604: Spring 2023
• 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: Summer 2021
• I-10 mainlane reconstruction and widening from Loop 1604 to Pfeil 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 completion: Summer 2024
• I-10 frontage road conversion from Graytown Road to Pfeil Road: 
  • Conversion of two-way frontage roads to one-way operation
  • Anticipated completion: Spring 2020
• Loop 1604 overpasses: 
  • Raising and reconstruction of I-10 bridges over Loop 1604
  • Anticipated completion: Spring 2023
• Graytown Road overpass: 
  • Reconfiguration of the Graytown Road bridge over I-10 to become an underpass that aligns with the Graytown Road/I-10 eastbound and westbound frontage road intersections
  • Anticipated completion: Winter 2022 

Upcoming Construction Projects 

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

• I-10 East at I-410 Interchange in San Antonio (Phase I)
  •  Construct two direct connector ramps from northbound I-410 to eastbound I-10 and from westbound I-10 to southbound I-410 
  •  Reconstruct southbound I-410 from I-10 to US 87 (Rigsby Rd)
  •  Anticipated start: Spring 2021 
• I-10 mainlane reconstruction and widening from Graytown Road to the Bexar/Guadalupe County line: 
  •  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: Fall 2020

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, 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.

Traffic Updates

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

Public Involvement

TxDOT strives to proactively and effectively communicate with the public on mobility and safety issues that may be impacted by the construction of these improvements. Public involvement to-date on the I-10 East corridor includes the following:

• 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.
• The latest information on lane closures, traffic shifts, and project updates for all improvements currently under construction is provided through the following:
  • Local news media outlets.
  • The San Antonio District’s Go Ahead! blog and Twitter feed.
  • Portable Digital Message Signs stationed along the project corridor.
  • DriveTexas.org
