San Antonio Area Freeway System
PROJECT INFO: US 90 West Expansion (Loop 410 to SH 211)

This page last updated April 30, 2022


This project has changed!
The previous version of this page was based on preliminary schematics from 2018. Updated schematics were released October 15th, 2020 and some details have changed from the preliminary plans. This page has been updated to reflect the current plans. As always, some details may change prior to construction. This page will be updated again when the construction plans are released.

Project locationLocation
US 90 West from Old Hwy 90 to the Medina County Line

Advanced planning

Phase 1 is funded and it is expected construction could start in 2025. Future phases are currently unfunded and therefore have no timeline.

This project will ultimately upgrade US 90 from Loop 1604 to west of SH 211 from a four lane divided highway to a six lane freeway with access roads. It will also build the remainder of the flyovers at the Loop 1604 interchange, revise the SH 211 interchange, widen US 90 between Loop 410 and Loop 1604 to eight lanes (six mainlanes plus an auxiliary lane), and make various operational improvements along the remainder of the corridor east of Loop 1604. A separate project will construct the remaining flyovers at the Loop 410 interchange.

Because of the scale of this project and funding availability, it will be broken into multiple phases. The first phase will include most of the widening and improvements between SH 211 and Hunt Lane and the westbound US 90 to northbound Loop 1604 flyover. A preliminary project is constructing a westbound to eastbound turnaround at Montgomery Rd.

This project is a continuation to several improvements that have been made to a portion of this corridor recently.

How this project will help
Several new large subdivisions have been constructed along US 90 west of Loop 1604 in the past decade with several more planned or underway. As a result, traffic volumes along that stretch of US 90 have increased more than 70% over the past decade. Additionally, growth along the Potranco Road corridor just to the north is likely contributing to traffic in the US 90 corridor.
Upgrading this segment to a freeway will allow it to efficiently and safely handle current and expected traffic. Completing the Loop 1604 interchange will accommodate current and future traffic there.

The remaining upgrades will improve the operation of the Military Dr. interchange and facilitate the future flyovers in the Loop 410 interchange.

Below are the detailed schematics for Phase 1 and the ultimate build-out of this project from TxDOT with my own annotations added to help clarify and explain the various elements. Click on an image below to open the schematic in a new window that you can scroll and zoom.
