State Route 49 is a north–south state highway in the U.S. state of California that passes through many historic mining communities of the 1849 California gold rush and it is known as the Golden Chain Highway.

One of the bridges along SR 49 is named for the leader of the association, Archie Stevenot.

State Route 88 (SR 88), also known as the Carson Pass Highway, is a state highway in the U.S. state of California. It travels in an east–west direction from Stockton, in the San Joaquin Valley, to the Nevada state line, where it becomes Nevada State Route 88, eventually terminating at U.S. Route 395 (US 395). The highway is so named as it crests the Sierra Nevada at Carson Pass. The highway corridor predates the era of the automobile; the path over Carson pass was previously used for the California Trail and the Mormon Emigrant Trail. The mountainous portion of the route is included in the State Scenic Highway System.
Archie Stevenot was a prominent citizen in Calaveras County, California and Supreme Noble Grand Humbug of E Clampus Vitus. Born in Carson Hill, Stevenot helped found the California Chamber of Commerce and his family established the borax industry in the state. He also established the Mother Lode Highway Association in 1919 which was primarily responsible for the creation of State Route 49. As a result, the bridge across the Stanislaus River between Tuolumne and Calaveras counties on SR 49 is named the Archie Stevenot Bridge in his honor, and his birthplace has been declared a California Historical Landmark No. 769.

Parts of SR 108 are closed annually during the winter due to inclement weather along the summit.
