I-45 SB Main Lanes Blocked by Multi-Vehicle Crash Conroe

CONROE, TX – A major multi-vehicle accident has brought southbound traffic on Interstate 45 to a complete standstill Thursday morning, creating a massive bottleneck for commuters traveling into the Greater Houston area.

The Texas Department of Public Safety reported the crash occurred shortly before 7:00 a.m. on June 20, 2024, just north of the North Loop 336 interchange in Conroe. Preliminary reports from authorities on the scene suggest the incident involved a chain-reaction, rear-end collision involving several passenger vehicles.

Emergency response teams, including the Conroe Fire Department and the Montgomery County Hospital District, arrived quickly to provide medical assessment and clear the wreckage. While officials have not yet released the specific number of individuals transported to area hospitals or the severity of any injuries, the scale of the emergency presence indicated a significant impact on traffic flow.

The Texas Department of Transportation (TxDOT) confirmed that all southbound main lanes were forced to close to accommodate the emergency response and debris removal. Travelers attempting to head south are being diverted onto the frontage road, leading to severe congestion that began backing up for several miles toward Willis by mid-morning.

Traffic analysts are warning drivers to expect lingering delays even after the vehicles are cleared, as the volume of traffic during the peak morning commute continues to build. Motorists are strongly encouraged to utilize alternate north-south corridors such as FM 3083 or Highway 75 to bypass the incident site.

Authorities have not provided an estimated time for the reopening of the main lanes. Commuters are urged to monitor real-time traffic updates via the TxDOT Drive Texas website at drivetexas.org or through local traffic reporting apps before departing.

This is a developing story. Updates will be provided as more information is made available by the Texas Department of Public Safety.
