Crews were working throughout the night to repair Interstate 77 following a massive natural gas line explosion in West Virginia.
Tuesday's explosion destroyed four homes and damaged others. It melted guardrails and left a huge swath of the interstate in Sissonville impassible. Nobody was killed, but several people were treated for smoke inhalation.
The explosion closed a major commuter route for those in and around the state's capital.
Gov. Earl Ray Tomblin said a roughly 800-foot section in both directions was baked by the heat.
Transportation Secretary Paul Mattox said crews planned to work overnight removing the asphalt and grinding the roadway down to the original concrete before repaving. The state hopes to have the highway reopened by Wednesday night.
Federal and state officials are investigating what caused the explosion.
