Construction on part of the High-Speed Rail project came to a halt on Wednesday as crews battled a fire at the Church Avenue overpass in southeast Fresno. "There's a lot of plywood and lumber that's involved in this," Josh Sellers with Fresno Fire said. Workers, all unharmed, watched as firefighters attacked from above. "We have the railroad tracks here that we ended up having to close down and stop the trains because we have a ladder truck in place that's blocking the tracks," Sellers said.
