San Antonio Highway Closure: What You Need to Know (2026)

Get ready, San Antonio drivers! A major highway closure is coming your way, and it's going to last for days. The Texas Department of Transportation (TxDOT) has announced that Loop 1604 will be closed from Friday night to Monday morning, causing significant disruptions to your daily commute.

But here's where it gets controversial... While TxDOT assures that access to businesses in the area will be maintained and law enforcement will be on-site to direct traffic, the closures will impact multiple lanes and exits.

Let's break it down:

  • Westbound Loop 1604 exit ramp to the frontage road before the interchange
  • Eastbound and Westbound Loop 1604 mainlanes right lane at the interchange
  • Eastbound and Westbound Loop 1604 frontage road at the interchange
  • Eastbound and Westbound I-10 mainlanes at the interchange
  • Westbound I-10 frontage road from the entrance ramp north of the interchange to LaCantera Parkway
  • Westbound I-10 exit ramp to La Cantera Parkway

And this is the part most people miss: the WB exit ramp to La Cantera Parkway will be closed from Friday night to Saturday noon.

So, what are the recommended detours?

For drivers on the Eastbound Loop 1604 frontage road, you'll need to navigate through the I-10 interchange by keeping right onto the EB I-10 frontage road, taking the UTSA Blvd. U-turn to the WB I-10 frontage road, and then keeping right to return to the EB Loop 1604 frontage road.

Similarly, those on the WB Loop 1604 frontage road will continue through the interchange by keeping right onto the WB I-10 frontage road, entering the WB I-10 mainlanes, and then exiting at Camp Bullis Road for a U-turn. You'll then enter the EB I-10 frontage road and keep right to re-enter the WB Loop 1604 frontage road.

Drivers on the WB Loop 1604 mainlanes should exit at Lockhill Selma Road to the frontage road, keep right onto the WB I-10 frontage road, and enter the WB I-10 mainlanes using the first available entrance ramp.

For those on the EB I-10 mainlanes continuing through the Loop 1604 interchange, follow signs to WB Loop 1604 and use the flyover to enter the WB Loop 1604 mainlanes. Then, exit at Kyle Seale Parkway, take the turnaround to the EB Loop 1604 frontage road, and enter the EB Loop 1604 mainlanes using the first available entrance ramp. From there, follow signs to EB I-10 to rejoin the EB I-10 mainlanes.

And for drivers on the WB I-10 mainlanes, continue through the Loop 1604 interchange and then exit to the WB I-10 frontage road via Exit 556B. Follow the frontage road through the interchange and re-enter the WB I-10 mainlanes at the first available entrance ramp. If you're already on the WB I-10 frontage road, you can enter the mainlanes before La Cantera Parkway and then exit again at Camp Bullis Road to return to the frontage road. Those accessing La Cantera Parkway can use the Camp Bullis Road U-turn to the EB I-10 frontage road, where you can turn right or left onto La Cantera Parkway. The La Cantera Parkway intersection will remain open.

This closure is a significant event, and it's important to plan your routes carefully. Remember, construction is weather-dependent, so keep an eye on the forecast!

So, San Antonio, are you ready for this major highway closure? How do you plan to navigate these detours? Let's discuss in the comments and share our strategies!
