San Antonio Area Freeway System
Construction Projects

This page last updated October 10, 2014

"Creation is messy work."

This page contains information about current and future major freeway improvement projects in the San Antonio area.  These are expansion, new construction, or TransGuide projects; maintenance and repair projects are not included.  Data for this page comes from a variety of sources including media reports, TxDOT, ARMA, and MPO data as well as personal knowledge.  All information is subject to change.  This is not an official website. 


Current & scheduled projects

The following is a map and list of major San Antonio area freeway projects currently underway or with scheduled start dates in the next year or so.  The numbers and letters on the map correspond to the listings on the table below.  Letting, start, and completion dates are from various sources and represent the latest estimated date that I know of as of the date this page was updated.  Project schedules are in a state of constant flux, so all dates shown here, especially for scheduled and proposed projects, are subject to change.  Items listed in the "Final planning" section that are designated as "Unfunded" indicates that the project is essentially ready for construction but is awaiting funding.
