This page last updated September 28, 2024 |
This page contains information about current and future major freeway expansion and improvement projects in the San Antonio area. Minor projects, as well as maintenance and repair jobs, are not included (there's just not enough room to list them all here!) Data for this page comes primarily from official TxDOT, ARMA, and MPO project databases, as well as from media reports and the author's personal knowledge. All information is subject to change.
This is not an official website. The completion percentage data on this page was last updated September 20, 2024.

Current and near-term projects
The following is a compendium of major San Antonio area freeway projects currently underway or in advanced planning. The numbers and letters on the map correspond to the listings on the table below. Letting, start, and completion dates represent the latest estimates that could determined as of the date this page was updated.
Occasionally, TxDOT may grant extra time to complete a project due to issues beyond the contractor's control. When this happens, you may notice the completion percentage on a project decrease from one month to the next.
Because I use my own method for calculating the completion percentage, it may not always match information from other sources. In the end, construction progress is always fluid and somewhat subjective, so any advertised completion percentage should always be considered approximate.
- The contractor's estimated date if available.
- TxDOT's estimated date if available.
- My own calculation based on the number of contracted working days for the project.
I use quadrimesters starting in January for the descriptors of "early", "mid", and "late".
In the "advanced planning" section, projected start dates are either when a project is estimated to start construction if already funded, or when funding may be available for a project based on current projections. For this, I generally use the projected bid date in TxDOT's project tracker database and add a few months to that unless there are other authoritative reports of a different start date.
Project schedules are always in a constant state of flux. For projects underway, weather, resource availability, engineering issues, and other factors can cause projected completion dates to slip, and occasionally the stars align and work is completed earlier than expected. For projects in planning, funding availability, engineering issues, environmental clearances, right-of-way acquisition, utility relocation, changing priorities, and other red tape can cause projected start dates to slip. Occasionally, start dates can get moved up due to unexpected funding availability or a shift in priorities.
The upshot: All dates shown here are always subject to change.
