IH-45 Gulf northbound shut at Monroe Road after major crash

September 23, 2026 at 06:15 AMBy Dennis R. Mundy, Executive Editor📍 Harris County

A major crash brought northbound I-45 to a standstill at SH-3/Monroe Road early Wednesday morning. The collision happened at 6:15 AM, forcing authorities to close multiple lanes as they worked the scene.

The backup stretched for miles during the morning commute, with delays compounding as drivers tried to navigate around the blocked highway. If you're heading north on 45 through this corridor, expect significant slowdowns or plan an alternate route entirely.

Hardy Toll Road, SH-249 to the northwest, or local routes via Airline Drive can help you bypass the congestion. Crews worked to clear the roadway, but the morning rush meant every minute added frustration for thousands of commuters trying to get to work.

This crash is part of a troubling pattern at this location. According to LTA data, IH-45 northbound at SH-3/Monroe Road has logged 38 incidents over the past 90 days—30 of them major. In just the last 12 months, the corridor has seen 91 total incidents, including 51 major crashes and 2 fatalities.

Looking at the long view, TxDOT CRIS public crash records show 337 crashes within a quarter-mile of this corridor since January 2020, with 4 fatalities. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 131 crashes. Additionally, hit-and-run incidents account for 11.7% of crashes here—78 of the 665 units involved fled the scene.

While crashes at this location occur throughout the day rather than concentrating in a single rush hour, the heaviest concentration comes between 4 and 5 PM, when the LTA database recorded 6 crashes in that single hour.

Conditions were clear at the time of this morning's crash—partly sunny with temperatures around 80°F. The roadway should clear as crews finish their work, but give yourself extra time if you're traveling through this section of northbound 45 today.
