California State Route 88

Spring storm on May 28, 2008

SR 88 begins just outside Stockton as Waterloo Road, heading northeast towards Waterloo and Lockeford. Leaving the city, and in between the small towns served by the route in the San Joaquin Valley, the route passes by several farms, vineyards and orchards, some of which have roadside stands and stores.[6] Shortly after separating from a brief concurrency with SR 12, the highway enters Amador County and gradually begins an ascent up the foothills of the Sierra Nevada.

Between Sunnybrook and Martell, both small towns along the ascent to Jackson, the road joins with the corridor of the Amador Central Railroad, an abandoned freight rail line, purchased and operated by the Amador County Historical Society and other heritage railway enthusiasts who sponsor occasional heritage trains along the route.[7][8] Jackson is the largest town traversed in the Sierra foothills by the highway. The highway joins with State Route 49 through part of the town. Route 49 is heavily connected to the California Gold Rush of 1849. Many locations along SR 49, including Jackson, are a significant part of California's Gold Rush era history and have a rich gold mining history.[9] [10][11] Both routes 49 and 88 have been re-routed around the historic part of downtown and instead pass on a four-lane road to the west of the historic district.[5] SR 88 separates from 49 and leaves Jackson following Jackson Creek to climb to the small town of Pine Grove, where Route 88 reaches the ridge it follows to scale the western slope of the Sierra Nevada. Along this ascent the road passes to the south of the Jackson Rancheria of Me-Wuk Indians and SR 88 is used as an access road for both the tribal nation and the Jackson Rancheria Casino Resort operated by the tribe.

From Pine Grove east, highway 88 follows a ridge that separates the watersheds of the North Fork Mokelumne River with initially the watershed of Sutter Creek, later that of the South Fork Cosumnes River, later still that of the Middle Fork Cosmunes River, and at the highest elevations with the Silver Fork of the American River. At several points along the ridge the route features places to pull over and view into the canyons of each of these rivers. For several miles this ridge, and by extension SR 88, form the boundary between Amador and El Dorado County.[5] In the lower parts of this ridge are the settlements of Pioneer and Buckhorn. There are two small settlements in the higher elevations of this ridge, Cooks Station, and Ham's Station. Both of these are today known as locations where Caltrans frequently implements restrictions during winter storms, such as requiring tire chains, restricting certain vehicles or complete closures. Where this ridge crosses the divide between the Cosumnes and American Rivers is where the road joins the Mormon Emigrant Trail, which follows a different ridge up the mountains from the modern U.S. Route 50 corridor near Sly Park.[5] The Mormon Emigrant Trail is so named for the Mormons in California during the California Gold Rush, who created this path to rejoin the Mormon migration to Utah.[12] Just past Silver Lake, Route 88 reaches a geographic feature known as the Carson Spur. This is where this ridge effectively ends, and the road follows a dynamited path down to Kirkwood and the Kirkwood Mountain Resort. This is also near where SR 88 crosses into Alpine County.[13] The Carson Spur section is known for frequent avalanches in the winter and is periodically closed for avalanche control measures.[14][15] In the final push up to Carson Pass the road passes by Caples Lake.[5]

While the road uses ridges for the western approach to Carson Pass, the eastern approach rapidly descends into the Carson River canyon, with a view area of Red Lake along the descent into Hope Valley. While at Pickett's Junction in Hope Valley, the highway joins with SR 89, and the two routes are concurrent through Woodfords Canyon of the Carson River, which provides the final descent out of the Sierra Nevada. At the mouth of the canyon is the small town of Woodfords, here SR 89 separates from SR 88 and proceeds towards Markleeville.[5] Hope Valley, Woodsfords Canyon and Markleeville are often cited as one of the best areas for autumn foliage viewing in the state of California.[16][17] Shortly after exiting the mountains the highway reaches the Carson Valley, where the highway turns due north and becomes one of the main thoroughfares of the valley. Here SR 88 reaches the Nevada state line and becomes Nevada State Route 88.[13]

SR 88 is part of the California Freeway and Expressway System[18] and the National Highway System.[19][20] The portion over the Sierra Nevada is included in the State Scenic Highway System[21][22][23] and is designated a National Forest Scenic Byway.[2] Route 88 is one of three routes to continue with the same route number after crossing into Nevada, the others being Routes 28 and 266.

Highway 8 in Amador County, circa 1930s

A portion of modern Route 88 (from Antelope Springs to the border) started as the Amador/Nevada Wagon Route, a toll road with a franchise grantedin 1852[24] and surveyed in 1857.[25] While the route was based on the Kit Carson trail and Old Emigrant Road, a significant part of this toll road was funding a realignment of the portion from Tragedy Spring to Caples Lake. In its original form, the road looped around the Silver Lake basin, over a high mountain ridge near Emigrant Lake reaching an elevation of 9,640 feet (2,940 m). This was a treacherous routing, and was rerouted via blasting a path through the Carson Spur, similar to the modern route, in 1863.[26] The path through the Carson Spur was re-dynamited and widened to its current form in 1960[24]

The first numerical designation for the Amador County portion of modern Route 88 was Route 8. Old SR 8 overlaps present SR 88 from Alpine County to Jackson but unlike modern SR 88 continues south to Mokelumne Hill, then to Valley Springs along modern State Routes 26 and 49. A small portion west of Jackson was part of SR 104[27]

Significant parts of the highway have been re-aligned and improved from the original wagon trail. A bypass of Jackson's historical district was completed in 1948.[9] The highways in the area were re-aligned to their modern designations, including the 88 designation, by the time the predecessor agency to what is now called Caltrans announced significant improvements to the road had just been, or soon would be, completed in 1958. These improvements included a re-alignment of the eastern approach to Carson Pass to reduce the grade by passing Red Lake to the north rather than along the southern shore, paving a new route west from Martell and re-alignments along parts of the ridge, including a new alignment around an area called Peddler's Hill.[28]

The highway was not originally maintained in the winter, but became the latest trans-Sierra Nevada highway to remain open year round in 1971. Coinciding with an expansion of the Kirkwood Mountain Resort - which lies between Carson Pass and the Carson Spur - the developers agreed to build and donate maintenance facilities for Caltrans and contribute funds for snow plowing.[29]

Historical landmarks

As the SR 88 corridor has history that predates the automobile, there are a number of historical markers and landmarks along the roadway. These include:

• The Trail of the 1844 John C. Frémont Expedition, at the northwest corner of the Calaveras River (postmile SJ 6.09)[30]
• Clinton, on Clinton Rd., south of the highway, in Pine Grove—Clinton was the center of a placer mining community during the 1850s and of quartz mining as late as the 1880s. This town once decided Amador County elections as its votes were always counted last.[31]
• Irishtown, at the intersection of Pine Grove Wieland Rd. in Pine Grove—This was an important stopping place for emigrants on their way to the southern mines. The first white settlers on this spot found it a "city of wigwams," and hundreds of mortars in the rocks testify that this was a favorite Indian camping ground.[32]
• Maiden's Grave, burial place of Rachel Melton (d. 1850), a young girl who died while traveling to California via covered wagon (postmile AMA 61.3)[33]
• Cooks Station, a roadside stop built in 1863 and still in operation, elevation 5,000 feet (1,500 m)
• Ham's Station is a roadside stop still in operation as a restaurant and convenience store, located at 38.544406°N 120.377471°W / 38.544406; -120.377471 at an elevation of 6,000 feet (1,800 m). Ham's Station was built by 1879 and originally served as a toll station on the highway.[34][35]
• Tragedy Spring, where 3 of the Mormons who helped build the Mormon Emigrant Trail were killed.[12]
• Two markers note the original alignment of the Old Emigrant Road that was bypassed with the construction via the Carson Spur. One is at the intersection of Mud Lake Rd (postmile AMA 63.1). The second marker is at postmile ALP 2.4, at Caples Lake.[26]
• The Kit Carson Marker (CHL #315, postmile ALP 5.2), at the summit of Carson Pass, marks where Carson carved his name into a tree in 1844 while guiding John C. Frémont through the Sierra Nevada. The original can be found at Sutter's Fort, Sacramento.[36]
• On some large rocks near Carson Pass, a group of pioneers inscribed their names and the emblem of the Independent Order of Odd Fellows in 1849 (postmile ALP 5.3).[37]

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see California postmile § Official postmile definitions).[38] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
