A fatal traffic collision brought the northbound lanes of Interstate 45 to a standstill early Sunday morning near the interchange with Interstate 610. Houston Police Department responded to the crash at 3501 North I-45 Freeway at the I-610 exit ramp at 4:14 AM on March 22, 2026. The incident resulted in at least one fatality, according to HPD.
The early morning timing likely contained the immediate traffic fallout, though the northbound I-45 corridor was heavily impacted during the crash investigation and cleanup. Drivers heading north toward The Woodlands or deeper into North Houston faced significant delays as emergency crews worked the scene. Alternate routes into the northern areas included taking I-610 west to US-290, or diverting south on I-45 to connect with other eastbound or westbound thoroughfares depending on final destinations. Those navigating the elevated feeder roads around the interchange experienced the heaviest congestion.
The I-45 and I-610 interchange sits in a critical juncture of Houston's transportation network, serving as a major gateway for traffic moving between downtown, the North Loop area, and northern suburbs. This stretch of northbound I-45 regularly handles heavy volumes of commercial and commuter traffic, even at off-peak hours. The I-610 exit ramp area has seen its share of incidents over the years, given the complexity of the interchange geometry and frequent merge movements.
The northbound mainlanes remained affected through the early morning hours as investigators documented the scene. Houston PD had not released details about whether lanes have been fully cleared as of publication. Drivers planning to use northbound I-45 in the coming days should allow extra time and monitor traffic updates, particularly during morning and evening commute periods when this corridor reaches capacity.
