The San Diego Union-Tribune: "Asked why the cost of building new highways and roads was spiking, Caltrans District 11 acting Director Cory Bims blamed the fluctuating cost of raw materials.
“It can be very volatile,” he said. “Major construction items for projects, steel and concrete and asphalt, there’s lot of things that influences those costs. It can come back down again as quickly as it went up.”"
