VIDEO: The National Transportation Safety Board has released a preliminary timeline on a gas pipe explosion and fire that destroyed homes in Hayward late last year. The disaster occurred after an asphalt crew struck an underground gas line, leading to a massive blast less than two hours later.
On the morning of Dec. 11, a crew from Mayo Asphalt Milling was working on the East Lewelling Boulevard roadway and sidewalk project. While digging in the 800 block of East Lewelling Boulevard, the crew ruptured a natural gas line owned by Pacific Gas & Electric.
Initial reports identified Redgwick Construction as the party that struck the line. However, the NTSB clarified that Mayo Asphalt Milling, a subcontractor on the project, was responsible for the rupture. PG&E was notified of the damage to the service line at 868 East Lewelling Blvd. at approximately 7:25 a.m.
