It runs from Interstate 5 in the town of Mount Shasta City to a dead end at the 8,000-foot (2,400 m) level on 14,162-foot (4,317 m) Mount Shasta. The route follows Lake Street, Mount Shasta Boulevard, Alma Street, and Rockfellow Drive, right before reaching Everitt Memorial Highway.
The highway, completed in 1958 at a cost of $980,000 and designated in 1959,[1] was originally built to provide access to the Mount Shasta Ski Bowl, which was destroyed by an avalanche in 1978.[3] Today, the highway provides access to Mount Shasta for climbers, skiers, and anyone wanting access to the mountain.

County Route A12 (CR A12), known locally as the "99-97 Cutoff", or more commonly, "the 97 cutoff", is a two-lane rural highway in Siskiyou County, California, United States, with a length of 17.9 miles (28.8 km).[1] A12 begins in the west at its junction with Old 99 Highway, which was once US 99. Just a few dozen yards to the east, it intersects Interstate 5. Its eastern terminus is at US 97, 12 miles (19 km) north of Weed.
One mile east of the Interstate junction, it passes through the tiny village of Grenada, the only population center of any merit along the route. 7 miles (11 km) further east is the burg Mayten, which consists only of a convenience store, a church, and an elementary school.
The route is heavily used by travelers and truckers southbound on Interstate 5 who wish to use US 97 northbound en route to Klamath Falls and points north. This route saves over 13 miles (21 km) than if the alternative routing via I-5 to Weed, then north on US 97 was used. Hence, the local name "97 cutoff".
The western two-thirds of the route passes through agricultural areas, and is very reminiscent of two-lane farm roads in California's Central Valley. However, the eastern portion is very scenic, passing through an area with towering dark red crags and buttes to the north.

County Route A28 (CR A28) is a two-lane rural highway in Siskiyou County, California, United States, connecting CR A12 (the 99-97 Cutoff) to Copco Road near Hornbrook. The route is known as Montague Grenada Road, 11th Street in Montague, and Ager Road.
CR A28 begins at CR A12 in Grenada, connecting Grenada with Interstate 5 near Hornbrook via Montague. It is a flat, level route, and for this reason, was the original preferred routing for both US 99 and I-5 through the area. In both instances, the routing was changed because of intense lobbying by officials in Yreka, who decried the fact that the major highway through the county would bypass the county seat. Thus, both highways ended up being built over far more rigorous terrain at a huge cost increase.
A28 serves the aforementioned three towns, as well as numerous homes and ranches along the way.
