Major crash blocks River Valley Drive in north Harris County

Emergency crews blocked part of River Valley Drive in north Harris County after a significant crash sent Precinct 4 constable deputies to the scene, and drivers were told to avoid the area.

The roadway was partially blocked while deputies investigated, leaving the stretch around River Valley Drive and nearby north Harris County streets unsettled as responders worked through the crash. No immediate clearance time was announced in the available update.

The disruption comes in a part of the county that has seen repeated serious wrecks on Aldine Westfield Road, where Precinct 4 has handled multiple closures and traffic alerts. On Feb. 18, 2026, deputies responded to a fatal crash at Aldine Westfield Road and Ciderwood Drive involving an off-duty Harris County Sheriff’s Office deputy riding a personal motorcycle.

Sheriff Ed Gonzalez identified the victim as Deputy Ricky Zaragosa, 33, and said he had three years of service with HCSO. Precinct 4 Capt. Aaron Strain said Zaragosa was confirmed dead at the scene, and officials said investigators kept the crash site active for hours while they worked to determine what led up to the collision.

Officials also said a separate Montgomery County Sheriff’s Office deputy was arrested on suspicion of DWI at that scene, though that person was not involved in the wreck itself. The Feb. 18 crash added to a long list of major incidents along Aldine Westfield, where Precinct 4 has previously reported shutdowns near Treaschwig Road, Bellchase Drive, E Louetta Road, Cypresswood Drive and FM 1960.

For drivers moving through north Harris County, the current River Valley Drive crash again highlights how quickly the area’s smaller roads can be tied to larger corridor problems. When Aldine Westfield backs up, traffic can spill across a wide stretch of the area, and when a roadway is partially blocked, response crews and investigators often keep lanes restricted until the scene is secure.
