State Route 4 Transportation Management Systems Upgrade

pa&ed phase

The California Department of Transportation (Caltrans) proposes to improve the mobility of travelers on State Routes 4, 12, 26, 33, 88, 99, and 120, Interstate 5, and Interstate 205 by updating Transportation Management System elements at 37 locations across San Joaquin County that are obsolete or do not meet current Caltrans standards. The project would also install new fiber-optic cables at eight locations, upgrade or install traffic monitoring stations in cabinets at nine locations, install weather information systems at six locations, install pull boxes at six locations, install a sewer hole at one location, upgrade motor vehicle pullouts at four locations, and replace or install closed-circuit television cameras at 25 locations.
