"I'm, we, feel real bad about the other family. I hope they'll be okay," she said. "My son tell me he was coming home."
All lanes of the I-45 North Freeway northbound at Crosstimbers were blocked for several hours Sunday by the fatal accident.
Houston police say Allen Kwan was drunk when he drove into a construction zone around 3:30am.
"He went inside the barricaded area where the construction workers were and struck the construction worker," Houston police Sgt. Kerry Shaw said.
The 33-year-old construction worker was leveling off a section of the road in the far left lane when the car veered over and struck him.
The man was killed.
Kwan stopped at the scene after the accident.
"The driver has been arrested under suspicion of driving while intoxicated," Shaw said.
He was charged with intoxication manslaughter.
According to police, Kwan said he thought he had already passed the construction zone.
Neither Kwan nor his female passenger were injured.
The victim was an employee of Angel Brothers Enterprises out of Baytown for the past five years. He was married with a daughter.
His employer has filed a worker's compensation claim on victim's behalf. They have also notified OSHA.
Kwan's mother grieves for him, and for the family left without a husband and father.
"I feel real sorry about that family that it happened. But nothing much I can do about it right now," she said.
The construction worker's name has not been released. An autopsy is scheduled for Monday to determine the exact cause of death.
