The Rest of the I-10 and Loop 1604 Rebuild Is Happening at Street Level

By 5 a.m. on Feb. 5, 2026, TxDOT was scheduled to open the eighth and last flyover at the I-10 and Loop 1604 interchange. That ramp carries westbound Loop 1604 traffic to westbound I-10 toward Boerne. Community Impact reported that drivers get on it just past Lockhill Selma Road and come down onto the I-10 mainlanes past La Cantera Parkway. From a car on the flyovers, the interchange looks finished.

The top levels are done. What's left is the street-level work below them: the frontage roads, entrance ramps, U-turns and intersections that lead to The Shops at La Cantera, The Rock at La Cantera, The Rim and UTSA. For anyone who lives in The Dominion, that is the part of the interchange used for errands, not for crossing town. Over the past two months the work there has changed in kind. It used to mean overnight closures. Now it also means permanent closures.

What's Built at Each of the Five Levels

TxDOT's Loop 1604 North Expansion is a $1.4 billion, 23-mile program running from SH 16 to I-35. Its centerpiece replaces the old I-10 and Loop 1604 cloverleaf with a five-level direct-connect interchange. In the February report, Community Impact laid out what goes on each level, based on TxDOT's description.

• Levels four and five: eight flyover ramps for higher-speed connections between Loop 1604 and I-10. All eight are open.
• Level three: the Loop 1604 mainlanes, each direction gaining one more mainlane and an HOV lane, plus collector-distributor roads along the outside and 18.5 feet of clearance for large trucks.
• Level two: the I-10 mainlanes, with room kept for future widening, and new collector-distributor roads that let local traffic skip the roundabouts.
• Level one: roundabouts at ground level for access to adjacent properties, new turnarounds and sidewalks along I-10, and a rebuilt VIA Park & Ride sized to fit under the new structure.

The flyovers opened in stages over 14 months. The first, from eastbound Loop 1604 to westbound I-10, opened in December 2024. Others followed in June, August, September and October 2025, two opened together in November 2025, and the last opened in February. Each one took long-distance traffic off the old loops. None of them changed how anyone gets into the La Cantera Parkway intersection or onto a frontage road, because those connections live on level one, and level one is where crews are working now.

VIA's Park & Ride page still lists the University Park & Ride at North Loop 1604 West and IH-10 West as closed for corridor construction.

This Fall, Some Closures Became Permanent

The overnight closures most drivers came to expect were temporary. A lane closed at 9 p.m. and reopened by 5 a.m. Since September, a different kind of change has appeared at the bottom of TxDOT's notices. These closures stay closed.

KSAT reported the September closure and the Hausman Road detour. KTSA's Oct. 5 roundup listed the closed Loop 1604 entrance ramp and the restricted frontage lane as long-term, 24-hour conditions, and KTSA's Oct. 23 update listed both again.

The Sept. 14 closure has a stated purpose. In KSAT's account, it makes room for future roadway improvements, including a new ramp built to get drivers past the traffic at La Cantera Parkway.

The One Opening Due Before New Year's

That ramp is the UTSA Boulevard bypass. KSAT reported in September that it is scheduled to open at the end of 2026. In a December 2025 report, KSAT described it as a bypass exit ramp from eastbound I-10 to UTSA Boulevard, part of a later phase that also widens the I-10 mainlanes.

The ramp is meant for the most familiar backup in this corridor. Eastbound I-10 drivers headed to UTSA Boulevard currently have to pass the La Cantera Parkway exit and its traffic on the way. The bypass is designed to separate those two streams. It is the one piece of the street-level work with a public opening target inside the next few months. "End of this year" is a schedule, not a ribbon-cutting date, and the same reports note that closure timing can shift with weather.

The Finish Date Has Moved to 2028

When Gov. Greg Abbott and TxDOT broke ground in October 2022, the governor's office announcement put Segment 2, the interchange, at $418 million with completion expected in 2027. A December 2024 TxDOT bulletin named Williams Brothers Construction as contractor, said construction began in late summer 2022, and also gave 2027 as the finish year. Community Impact's February report still used 2027 and put the interchange at 70% complete.

TxDOT's project segments page now lists Segment 2 with an estimated completion of 2028 and an estimated cost of $463 million. It also says construction across the corridor will continue through 2028. TxDOT's Texas Clear Lanes page still shows 2022 to 2027 for the same interchange. The segment page is the more detailed listing, and 2028 is its current estimate.

In practical terms, the street-level work described above, including the roundabouts, turnarounds, collector-distributor roads, HOV lanes and rebuilt Park & Ride, is likely to shape trips to La Cantera through at least one more full calendar year after this holiday season. No public date has been set for any of those ground-level pieces.

Holiday Evenings Fall Between the Closure Windows

The closure pattern in KTSA's October reports followed two windows. Weeknight closures ran from 9 p.m. to 5 a.m., and daytime closures ran from 9 a.m. to 3 p.m. on I-10 between Camp Bullis Road and De Zavala Road and on Loop 1604 near the interchange. Overnight, those notices listed full ramp and intersection closures on La Cantera Parkway, the eastbound I-10 frontage road closed between Via La Cantera and UTSA Boulevard, and the Loop 1604 frontage road closed in both directions between I-10 and Vance Jackson Road. In daytime, U-turns at La Cantera Parkway closed one at a time. Camp Bullis Road is the north end of that I-10 work zone.

The early-evening holiday events on the La Cantera side fall in the gap between those windows, after daytime work ends at 3 p.m. and before overnight work starts at 9 p.m.:

1. Coyote's Corn Corral at The Rock at La Cantera runs through Nov. 8, according to the Spurs' Rocktober announcement.
2. The annual tree lighting at Signia by Hilton La Cantera, 16641 La Cantera Parkway, is Nov. 20 at 5:30 p.m. Visit San Antonio's event listing gives admission as $15 for adults and $5 for children.
3. Holidays at The Rock, at 1 Spurs Way, opens Nov. 21 with a tree lighting and the rink opening, then runs through Jan. 3. The Spurs announcement says general programming is free and select activities cost extra.
4. Wrap & Rock, the holiday market at The Rock, runs Nov. 27 through 29, Thanksgiving weekend. Weekend closures followed their own schedule this fall: the Oct. 23 to 26 weekend ran nightly from 9 p.m. to 5 a.m., including eastbound I-10 mainlanes at Loop 1604.
5. Jingle Bell Bark is Dec. 13, and Rock the Clock, the New Year's Eve party, is Dec. 31. A Dec. 31 night out stretches well past 9 p.m., so the drive home is worth checking against that week's TxDOT notice.

These windows describe October's schedule. TxDOT issues new closure notices week by week, and the permanent changes in the table above apply at every hour. Leaving from The Dominion for the Signia tree lighting or opening night at The Rock means the old eastbound I-10 entrance south of the interchange is gone, the frontage road has one fewer lane approaching Loop 1604, and the UTSA bypass may or may not be open yet, depending on how the year-end target holds.

For anyone getting ready to sell in The Dominion, the changing roads around I-10 and Loop 1604 are part of how buyers will picture the drive to La Cantera and UTSA this winter, and part of how a listing should describe it.
