I-10 Katy westbound crash at SH-99; 93 incidents in 30 days

A crash on I-10 Katy westbound at SH-99 Lanier Parkway shut down lanes early Wednesday morning at 2:22 AM, adding to an extraordinary run of collisions at this stretch of freeway.

The wreck occurred in moderate rain, and TxDOT reports wet conditions contributed to over 14,000 Texas crashes in the most recent annual reporting period. Crews cleared the roadway, but the incident underscores a persistent pattern at this location.

According to LocalTrafficAccidents.com data, this intersection has logged 93 incidents in the past 30 days—78 of them major crashes. Over the past 12 months, the location has recorded 264 total incidents, 207 of which were major. The sheer volume of collisions here stands apart even in Harris County, which saw 19,616 total incidents over the same 30-day window.

What makes this location particularly notable is its off-peak profile. While most freeway crashes cluster during rush hour, this spot sees the majority of its incidents outside traditional commute windows. Of the crashes at I-10 and SH-99 over the past 90 days, only 38 percent occurred during rush hour—meaning the road poses collision risk around the clock. The dominant incident type at this intersection is crash, and crashes dominate the data: Fridays are the worst day here (38 incidents in 90 days), but collisions happen every day of the week.

The 7 AM to 8 AM window is the peak crash hour at this location, with 16 incidents recorded in that single hour over the past 90 days. But the 2:22 AM timing of today's wreck shows how unpredictable conditions can be—this intersection generates collisions in the middle of the night just as readily as during morning or evening peaks.

If you're heading westbound on I-10 toward Katy this morning, expect residual delays near the interchange. Alternate routes include I-610 to the loop, Westpark Tollway heading west, or Washington Avenue and Memorial Drive if you're navigating inner-loop segments.

The roadway has been reopened, but this location's crash history suggests caution—especially in wet conditions. Drivers should reduce speed and increase following distance around SH-99 on the Katy Freeway.
