A major crash shut down IH-45 Gulf northbound at W Dallas Street early Wednesday morning, closing lanes at 4:48 AM on September 23 and backing up traffic in the northbound corridor.
The wreck left northbound lanes impassable during the pre-dawn hours when northbound traffic typically builds toward the morning commute. Crews worked to clear debris and reopen the roadway. The incident disrupted access to the Gulf Freeway during a critical window for early-shift workers and regional freight movement.
If you were headed north on I-45 from downtown, the Hardy Toll Road, SH-249 to the northwest, or local routes via Airline Drive offered ways around the blockage. Current conditions on those alternates weren't immediately clear, but they were your best options to avoid the closure.
