Exit 50B on northbound I-45 shut after major crash

A major crash shut down the exit 50B off-ramp on northbound I-45 at Cavalcade around 11:48 AM on Wednesday, July 15, backing up traffic and forcing drivers to seek alternate routes during the midday push.

Responding officers worked to clear the debris and reopen the ramp. The incident tied up traffic on the northbound mainline as crews worked the scene, with significant delays reported throughout the corridor as drivers slowed to navigate around the closure.

This crash marks another incident in a corridor that's seen intense activity over recent weeks. According to LocalTrafficAccidents.com data, the Exit 50B off-ramp and surrounding northbound I-45 stretch has recorded 55 incidents in the past 30 days alone—42 of them major. Over the past three months, the corridor has logged 130 total incidents, with 71 classified as major. That's a volume that demands attention from anyone traveling this stretch.

Looking at longer-term records, the data tells a stark story. Per TxDOT CRIS public crash records, this corridor has seen 919 crashes since January 2020, including 4 fatal crashes. The state's data shows that "Failed To Control Speed" is the most commonly recorded contributing factor at this location, cited in 365 of those crashes. Additionally, the hit-and-run rate here stands at 12.1%—236 of the 1,950 units involved in crashes at this location left the scene.

Fridays have historically been the single busiest day at this location over the past three months, with 20 incidents recorded. However, crashes occur at varied times here rather than concentrating in one specific window—though evening rush, particularly between 7 and 8 PM, sees the heaviest concentration with 9 crashes during that hour alone.

Weather conditions at the time of this incident were overcast with temperatures around 81 degrees—not a major factor in this particular crash, though conditions can quickly change on this high-traffic freeway.

For drivers heading north on I-45, the closure of exit 50b forced traffic to continue north to alternate exits. Check real-time traffic apps for current flow conditions, as the mainline may remain impacted even after the ramp clears. Expect the incident to tie up traffic for at least the next couple of hours during cleanup and investigation.
