TxDOT overnight I-35 southbound lane closures near Judson Road (July 9–10): what Cibolo commuters should expect

TxDOT scheduled overnight closures of the southbound main lanes of Interstate 35 near Judson Road on San Antonio’s Northeast Side during the nights of Thursday, July 9, and Friday, July 10. For Cibolo residents heading toward San Antonio on I-35, those hours were when drivers needed the most extra planning time and the most attention to detour signage.

Where the closures happened

Local reporting and TxDOT’s announcement focused the shutdown on the I-35 southbound main lanes at Judson Road on the Northeast Side. The KSAT report describes the affected segment as “on the Northeast Side,” with the closure at Judson Road.

When the closures were scheduled

TxDOT planned to close all southbound main lanes from 9 p.m. to 5 a.m. on both nights (Thursday and Friday). Both KSAT and the San Antonio Express-News tied the nightly window to the same 9 p.m.–5 a.m. timeframe.

Important caveat: KSAT noted the closure was weather-permitting and subject to change. That’s why commuters were advised not to rely only on a single posted alert.

What drivers were told to do (detour basics)

According to KSAT’s summary of TxDOT’s release, drivers were instructed to exit the southbound main lanes at the Judson Road off-ramp, which leads to the I-35 access road. Drivers could then enter an on-ramp back onto the southbound I-35 main lanes just south of Judson Road.

The Express-News similarly described a detour option that moved drivers off the closed lanes and onto the southbound frontage road area.

For Cibolo-area commuters, the practical takeaway was straightforward: during that 9 p.m.–5 a.m. window, plan around the expectation that southbound main-lane access near Judson Road would be disrupted and that navigation would shift to an off-ramp/access-road/re-entry pattern.

How Cibolo commuters should check for the next overnight change

Even when a schedule is posted, TxDOT emphasizes checking real-time conditions before you leave. TxDOT’s “Be your own traffic reporter” guidance points drivers to TxDOT’s DriveTexas traffic map, which includes closures, construction, road damage, traffic, weather impacts, and live camera feeds, with updates provided by TxDOT crews.

For overnight commutes toward San Antonio, that tool is the best “what changed since yesterday?” check—especially given TxDOT’s note that closures can be weather-dependent and subject to adjustment.

Bottom line for residents and workers who commute

These July 9–10 overnight closures are now in the rearview, but they’re a good example of what Cibolo commuters can expect when TxDOT schedules major work on I-35 in the San Antonio Northeast Side area: nighttime southbound main-lane disruptions paired with a specified detour and a reminder to verify the latest status before heading out.

If you commute during similar overnight windows in the future, build your plan around the detour pattern you see posted and confirm the live closure status in DriveTexas before you go.
