"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.  Data for this page comes from a variety of sources including media reports, TxDOT, ARMA, and MPO data as well as 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 are from various sources and represent the latest estimated date that could determined as of the date this page was updated.  Items listed in the "Advanced planning" section that are designated as "Unfunded" indicates that the project is essentially ready for construction (or nearly so) but is awaiting funding.

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.
