A crash on IH-45 northbound at SH-99 Lanier Parkway shut down lanes early Sunday morning at 3:44 AM. Responding officers cleared the road, but the incident adds to an alarming stretch of activity at this corridor.
According to LocalTrafficAccidents.com data, this location has logged 255 incidents in the past 30 days alone—210 of them major crashes. Over the past 90 days, the corridor has seen 475 total incidents. That's an average of more than 5 crashes per day at a single interchange.
