A major accident brought evening traffic to a crawl on State Highway 99 in Richmond at 6:07 PM Thursday, April 02, 2026. Fort Bend County emergency crews responded to the collision, which blocked lanes during the height of the evening commute and created significant backups across the corridor.
The timing of the crash couldn't have been worse for southbound commuters heading out of the Sugar Land and Missouri City areas. Drivers faced lengthy delays as traffic was diverted around the accident scene. Those heading south on 99 should consider taking Broadway Street or University Boulevard as alternate routes, while northbound traffic can shift to local roads through downtown Richmond to avoid the backup. The incident will likely create spillover congestion on connecting roadways through the evening, particularly on major intersections feeding into the 99 corridor.
State Highway 99 has proven to be a persistent trouble spot in Fort Bend County. Over the past 30 days, this stretch has recorded 57 total incidents, with 37 classified as major collisions. The corridor runs through a densely populated section of the county, serving as a vital north-south artery connecting Richmond, Sugar Land, and beyond. Heavy commercial traffic, coupled with high-volume commuter use during peak hours, has made this section of highway particularly prone to serious accidents.
The incident affected southbound lanes during the initial emergency response. Drivers heading through the Richmond area Thursday evening encountered significant delays and should remain alert for emergency crews and debris. Traffic conditions on 99 have historically taken considerable time to clear following major accidents on this heavily-traveled corridor, so patience will be necessary as crews work to reopen all lanes.
