According to Simplyyellowpages, State Route 24 or SR-24 is a state route in the U.S. state of California. The highway is in the northeast Bay Area metropolitan area, and runs from Oakland to Walnut Creek. It is the primary commuter route from the suburbs around Concord and Antioch to the major cities of Oakland and San Francisco. There is also a tunnel in the highway, the Caldecott Tunnel. The highway is also known as the Grove Shafter Freeway on the section east of the tunnel. The highway is 22 kilometers long.
Travel directions
The highway begins at a major interchange with I-580, which runs from San Rafael to Castro Valley, and I-980, which runs through downtown Oakland. There are 2×4 lanes available here, and a BART (Bay Area Rapid Transit) light rail runs in the median strip. Just before the SR-13, the BART leaves the central reservation. The SR-24 then runs through suburbs, reaching the Caldecott Tunnel, a tunnel with 3 tunnel tubes, one of which is a switch tube, which can be used in the rush hour direction. After the tunnel one enters suburbs with low densities. This is a scenic route. The first suburb is Orinda, a wealthy suburb of 18,000 inhabitants, hidden in forests. Here the BART line will again run into the central reservation. The next suburb is Lafayette, with 24,000 inhabitants. The highway ends in Walnut Creek, a larger suburb of 65,000, on I-680, the eastern bypass of the metropolitan area.
History
Between 1934 and 1937, the first two tubes of the Caldecott Tunnel were constructed. The tunnel opened to traffic on December 5, 1937. Construction coincided with the construction of the San Francisco-Oakland Bay Bridge, creating a rapid east-west route from Contra Costa County to San Francisco. In the late 1950s, the connecting road to Oakland and Walnut Creek was upgraded to a 2×2 divided highway, which was leveled in 1969-1970. In 1971, the freeway was fully completed between Oakland and Walnut Creek with the opening of the last freeway overpasses.
A third tunnel tube was constructed at the Caldecott Tunnel between 1960 and 1964. A right-of-way had already been purchased for this in the 1930s. The third tube opened in October 1964, after which the two old tubes were renovated. After that, the middle tube was used as an interchangeable track, as one of the first interchangeable tracks in the world. A fourth tunnel tube was constructed at the Caldecott Tunnel between 2010 and 2013. It was opened to traffic on November 18, 2013.

According to itypejob, State Route 26 is a state route in the U.S. state of California. The road forms an east-west route through the Central Valley and the Sierra Nevada, from Stockton to Pioneer. State Route 26 is 100 kilometers long.
Travel directions
State Route 26 begins on the outskirts of the larger town of Stockton at a junction with State Route 99. The first 30 kilometers leads through a fairly flat and agricultural area, after which you enter the foothills of the Sierra Nevada. There are a number of exurbs up the slopes here. East of Valley Springs is a short double number with State Route 12. The road then climbs further and crosses some not too deep canyons. The highest point of the road is more than 900 meters above sea level. The road ends west of Pioneer on State Route 88.
History
The road was originally numbered State Route 8, which was changed to State Route 26 in 1964. The road has somewhat secondary importance, since parallel connections do run through the Sierra Nevada, while State Route 26 does not. The road mainly serves some villages and exurbs on the slopes of the Sierra Nevada.
Traffic intensities
20,000 vehicles drive daily at the junction with State Route 99 in Stockton, which descends rapidly outside the city, with 7,000 vehicles to Linden and 4,000 to 8,000 vehicles to Valley Springs. Only 500 vehicles drive east of Happy Valley, rising again to 1,500 vehicles on the final stretch to Pioneer.
