A single 18-wheeler crashed on the northbound lower deck of Interstate 35 in downtown Austin, Texas, early on Monday, November 2, shutting down the lower deck in both directions for a time and snarling the start of the morning commute. Austin police received the call at about 3 a.m., according to CBS Austin, which attributed its reporting to the Austin Police Department and the Texas Department of Transportation (TxDOT). The crash happened near 15th Street, on the stacked downtown section of I-35 that runs past the State Capitol area. Police said no other vehicle was involved, and no one was injured.

TxDOT initially closed both directions of the I-35 lower deck while crews responded, CBS Austin reported. The southbound lanes were later reopened, but the northbound lower deck remained closed at the time of the station's last update, published at 4:59 a.m. local time. Austin police directed northbound motorists off the interstate and onto 15th Street as an alternative route while the closure remained in place.

KVUE, Austin's ABC affiliate, reported that all northbound lanes of I-35 near Martin Luther King Jr. Boulevard were closed early Monday after the driver of an 18-wheeler crashed into a median. KXAN, the city's NBC affiliate, also carried video of the semi crash on I-35 on Monday morning. The two locations named in the reports — 15th Street and the Martin Luther King Jr. Boulevard area — sit on the same short downtown lower-deck stretch, a few blocks apart.

What officials have — and have not — said

Neither Austin police nor TxDOT has said why the 18-wheeler crashed. The initial reports carried no information about the cause of the crash, the driver's identity, the trucking company involved, or what the truck was carrying, and no official statement had been issued on those points by Monday morning. CBS Austin described the incident as a developing story. What officials have confirmed is narrow but clear: one truck, no other vehicle, no injuries, and a closure that began with both directions of the lower deck shut before the southbound side reopened.

Why this stretch of I-35 matters

Interstate 35 is the main north–south freight and travel artery through Austin, carrying long-haul trucks between the Laredo border crossing, San Antonio, the Dallas–Fort Worth metroplex and onward to the Midwest. Through downtown Austin the highway runs on a distinctive double-deck section, with upper and lower decks squeezed through the city centre. When the lower deck closes, traffic has few easy escape routes: the upper deck, the frontage roads and surface streets such as 15th Street absorb the overflow, and delays build quickly across downtown.

The corridor is also in the middle of the biggest rebuild in its history. TxDOT's I-35 Capital Express Central project covers about eight miles of the interstate, from U.S. 290 East to State Highway 71/Ben White Boulevard, at a cost of about $4.5 billion. The project will remove the existing decks, lower the roadway, and add two non-tolled high-occupancy-vehicle managed lanes in each direction, along with rebuilt cross-street bridges and new bicycle and pedestrian paths. Construction began in October 2024 and is targeted for completion in 2033; the Martin Luther King Jr. Boulevard bridge segment, just north of Monday's crash scene, has reached its final traffic configuration, according to project updates.

What happens next

Crews were expected to clear the wreck and reopen the northbound lower deck once the scene was safe, but neither TxDOT nor Austin police had announced a reopening time in the initial reports. Investigators will still have to establish why a lone 18-wheeler ended up in a crash serious enough to close the deck — whether speed, fatigue, a mechanical failure or another factor played a role is not yet known, and no conclusion should be drawn until officials report one. The closure also landed on the morning before Election Day, Tuesday, November 3, when Austin traffic is expected to be heavier than usual around downtown polling and government offices.

For the many Punjabi and South Asian truck drivers who run Texas freight — the I-35 corridor links some of the busiest trucking routes in the southern United States — the practical news from Monday's crash is reassuring on the human side and inconvenient on the road side: nobody was hurt, but a single-truck crash in the small hours was enough to close the lower deck of the state's most important urban interstate for hours. Awaaz Punjab will update this story if Austin police or TxDOT release the cause of the crash or a confirmed reopening time.
