after nearly forty years of service from the original orthotropic deck wearing surface, myers and sons construction, a partnership between c. c. myers and sterling construction company, was the selected bidder to remove and replace the wearing surface on the highrise portion in 2015. the work required two full weekend closures on may 8–11, 2015 and may 22–25, 2015. the new polyester concrete wearing surface, developed by caltrans and used to great success in other bay area bridges, is anticipated to be at least as durable as the original epoxy asphalt concrete, according to laboratory tests.
