The southbound feeder road of Highway 59 just before Beltway 8 had been closed for the police investigation of the deadly accident, but it reopened at around 5:15am.
Houston police say at around 2:30am the 37-year-old man drove his car off the exit ramp, through the barricades and ended up on the feeder road.
With the amount of damage to the vehicle and the guardrail, police say it appears the driver was exceeded the posted speed limit of 60 miles per hour.
"We don't have any witnesses who actually saw what happened, but evidence here at the scene indicates that he was about to take the north-south ramp onto Beltway 8 when for some reason, failed to drive in a single lane and struck the guardrail," said Sgt. I Izaguirre with the Houston Police Department.
At this time, police say there are no signs of impairment.
"He was wearing his seatbelt. There is no indication at this time that alcohol was involved. There is no alcohol inside the vehicle, we didn't smell any odor of alcohol," Sgt. Izaguirre said.
No other passengers were in the car with him at the time.
