California State Route 24
State Route 24 (SR 24) is a heavily traveled east–west state highway in the U.S. state of California that serves the eastern side of the San Francisco Bay Area. A freeway throughout its entire length, it runs from the Interstate 580/Interstate 980 interchange (just east of the MacArthur Maze) in Oakland, and through the Caldecott Tunnel under the Berkeley Hills, to the Interstate 680 junction in Walnut Creek. It lies in Alameda County, where it is highly urban, and Contra Costa County, where it passes through wooded hillsides and suburbs. SR 24 is a major connection between the San Francisco–Oakland Bay Bridge/MacArthur Maze complex and the inland cities of the East Bay.
Route 24 is defined in section 324 of the California Streets and Highways Code:
Route 24 is from:
(a) Route 580 in Oakland to Route 680 in Walnut Creek.
(b) Route 680 in Walnut Creek to Route 4 near Pittsburg.
Route 24 is not fully constructed to extend east to near Pittsburg as it is defined .
SR 24 begins at the four-level stack interchange with Interstate 580 and Interstate 980 in Oakland; this interchange is located on top of Grove Shafter Park. SR 24 initially heads north before turning east near the Berkeley city limits. Route 24 rises from near sea level in downtown Oakland past its interchange with State Route 13, which is a freeway south of SR 24 (upgraded August 1999) and a surface street north of SR 24. After this, SR 24 crosses the Contra Costa County county line through the four-bore Caldecott Tunnel and offers some attractive views of the hilly terrain through which it passes. Some protection of the views comes from the highway's designation as a California Scenic Highway.
On the other side of the tunnel, SR 24 travels through unincorporated Contra Costa County before entering Orinda. SR 24 crosses the Mokelumne Aqueduct soon after entering the city of Lafayette. SR 24 terminates at the intersection with Interstate 680 just inside the city limits of Walnut Creek.
The Yellow Line of the Bay Area Rapid Transit (BART) system runs in the freeway's center median, excepting the vicinity of the Caldecott Tunnel and the approach to the interchange with Interstate 680.
SR 24 is part of the California Freeway and Expressway System, and is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. SR 24 is eligible to be included in the State Scenic Highway System; however, Caltrans has only designated it as a scenic highway between the eastern end of the Caldecott Tunnel and I-680, meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community. SR 24 is designated as both the Grove–Shafter Freeway, after streets the route travels along (Grove Street was later renamed Martin Luther King Jr. Way), and the William Byron Rumford Freeway, honoring the first African American elected to a state public office in Northern California, from the Caldecott Tunnel to the I-580 interchange segment of the MacArthur Maze, continuing henceforth as I-980 to the terminus with I-880.
