Exit 46 on I-45 South shuts after major wreck; 55 incidents in 30 days

A major crash at Exit 46 on Interstate 45 South near the Scott Street entrance ramp brought one of the busiest stretches of southbound 45 to a standstill early Thursday morning. The wreck happened at 1:32 AM on July 16, forcing responding officers to clear debris and assess the damage while traffic backed up behind the scene.

This location has become one of the most crash-prone spots in Harris County over the past month. According to LocalTrafficAccidents.com data, Exit 46 on I-45 South has logged 55 incidents in the past 30 days—34 of them major accidents. Over the past 90 days, the corridor has seen 213 total incidents, with 125 classified as major. That's a crash roughly every four hours, on average, at an interchange where drivers merge, exit, and navigate heavy southbound traffic.

The data tells a consistent story: this location doesn't have a single vulnerable hour. Crashes here occur throughout the day and night. The single busiest hour is 4 to 5 PM, when the corridor logs 13 crashes on average, but major wrecks happen just as readily at 1:30 in the morning, as this one did. Sundays historically see the highest incident count with 30 crashes in the past 90 days.

State crash records paint a wider picture. Per TxDOT CRIS public crash records, the corridor has experienced 1,694 crashes since January 2020 within about a quarter-mile of this exit, including 4 fatalities over that six-plus year span. Contributing factors as recorded by investigating officers show "Failed To Control Speed" as the single most common notation—cited in 661 of those crashes—though this doesn't mean speed caused every incident. Hit-and-run crashes account for 10.9 percent of incidents here, with 405 of the 3,705 vehicle units involved fleeing the scene.

Weather conditions at the time of Thursday's wreck were overcast and 78 degrees—dry conditions that don't explain the accident themselves, though this corridor's history suggests crashes happen regardless of weather.

Responding officers cleared the scene and worked to restore traffic flow. The exact duration of the closure and lane restrictions weren't immediately specified, but given the major classification and the time of day, the backup should have cleared before the morning commute hit peak volume around sunrise. Drivers heading south on 45 during the early-morning hours should remain alert at this exit; the sheer frequency of incidents here means another delay is statistically likely in the coming days.
