Route description

Route 4, an east-west highway, begins in Hercules at San Pablo Avenue next to the Interstate 80 junction as part of 'John Muir Parkway'. (The actual parkway extends a bit past the western terminus.) The road is an expressway between from its starting point until it approaches Martinez, at which point it becomes a full freeway (the 'California Delta Highway') passing Concord, Pittsburg, and Antioch. BART tracks run in the median of the freeway from the Port Chicago Highway interchange in Concord to the Bailey Road interchange in Bay Point, where the line currently ends at the Pittsburg/Bay Point Station. Access to that station is provided by a pedestrian bridge crossing over the eastbound lanes of Highway 4. After Antioch, the freeway turns northward toward the Antioch Bridge to become State Route 160, and Route 4 separates to become a suburban and rural road passing through the Bay Area's outermost eastern suburbs (Oakley and Brentwood). Route 4 continues to Stockton, where it briefly joins I-5 and then enters a separate freeway routing almost directly through downtown Stockton. The route then runs concurrent with State Route 99 before running eastward into the Sierra through Angels Camp and Calaveras Big Trees State Park. The route runs through the 8,050 ft. (2,454 m) Pacific Grade Summit on its way up to the 8,730 ft. (2,661 m) Ebbetts Pass and ends at State Route 89 ten miles west of Topaz Lake, on the California–Nevada border. The portion from Arnold to its terminus is designated the 'Ebbetts Pass Scenic Byway'.
Through the mountains, Route 4 is not suitable for large trucks, buses, or RVs, as it becomes very steep and narrow, with no center dividing line shortly after the Mount Reba Turnoff to Bear Valley Ski area, with tight switchbacks. The pass is not plowed for snow, and thus closes during the winter months often from November through as late as May. Thus, no passage between the Mount Reba Turnoff and Markleeville is possible. The western slope is plowed and rarely closes, even for a few hours, but often has chain restrictions during and immediately following storms, usually just east of Arnold The eastern slope is not plowed.
As of April 2006, a freeway extension from the route 160 junction bypassing Oakley and Brentwood to the south and west is in the various stages of planning and construction. [1] [2]

History

Pre-1964 Legislative Route 4 was originally defined in 1909 to travel 358 miles (576 km) between Sacramento and Los Angeles; this became U.S. Route 99.
