A major crash at Parkway Plaza Drive and Sienna Hill Drive around 11:36 a.m. on Sunday, July 26 left the intersection disrupted and raised fresh concerns about a location that's become a repeated flashpoint for collisions.
The crash sent multiple vehicles into the intersection during what should've been a relatively calm Sunday morning. Heat was pushing 93 degrees, skies were scattered with clouds, and conditions appeared routine — but the intersection itself tells a different story according to LTA data.
In the past month alone, six crashes have hit this intersection, with four of them classified as major. Over the past quarter, LTA's real-time incident database shows 19 total incidents here, thirteen of them major. The pattern is consistent: Sundays see the highest activity, with five crashes recorded on Sundays in the past 90 days.
According to TxDOT CRIS public crash records dating back to January 2020, fourteen crashes have occurred within a quarter-mile of this intersection. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in three crashes. The data also shows a hit-and-run rate of 11.5% at this location — three of twenty-six vehicles involved fled the scene.
Responding officers handled the scene Sunday, working to clear the roadway and document the incident. Specific injury details, lane closure information, and clearance timeline remain developing; LTA will update as information becomes available.
Harris County has recorded 17,682 incidents over the past 30 days, with 38 fatal. Sunday's crash at Parkway Plaza and Sienna Hill adds to a troubling local concentration that stretches across multiple reporting windows.
Drivers approaching this intersection should expect residual congestion as crews wrap up scene operations. If you're in the area, use alternate routes if available and allow extra time — the intersection's recurring crash history suggests caution is warranted even after the immediate incident clears.
