"Creation is messy work."

This page contains information about current and future major freeway improvement projects in the San Antonio area. Shown are major expansion or improvement projects; 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.


Current & near-term projects

The following is a map and list 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.

The percentage completed is computed by averaging the percentage of allotted working time and contract budget amounts used to date. This method takes both metrics into consideration and helps to eliminate inconsistencies that one metric or the other can often produce as a project progresses. If that average exceeds 100%, then the lower of the two metrics is used. If that still exceeds 100%, the project will be listed as 99% complete.

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 funding projections. 

Project schedules are in a constant state of flux due to weather and other factors for projects already underway and funding availability and other red tape for those in planning. Therefore, all dates shown here are always subject to change.
