Crews also are performing various road construction and bridge activities on Highway 99 from Highway 140 to State Route 59/Martin Luther King Jr. Way. Work will continue as follows:

The $32.4 million Highway 99 East Merced overhead project, which began June 11, 2012, will replace the bridge decks on the 15th Street undercrossing and the East Merced overhead structures. The project will bring the bridge widths and bridge rails to current standards, install a concrete median barrier, provide standard shoulder widths, and upgrade existing guard rails and bridge approach rails, according to Caltrans.
