State Route 89 is a California State Highway that travels in the north–south direction, and is the major thoroughfare for many mountain communities. It starts from U.S. Route 395 near Topaz Lake, winding its way up to the 8,314 ft (2,534 m). (2,534 m) Monitor Pass, down to the Carson River, and up again over the 7,740 ft (2,360 m). (2,359 m) Luther Pass. From that point on, the route generally loses elevation on its way past Lake Tahoe, through Tahoe and Plumas National Forests until Lake Almanor. For roughly nine miles the route is then a part of State Route 36. The route then ascends to the 5,753 ft (1,754 m). (1,753 m) Morgan Summit. After it enters Lassen Volcanic National Park it continues to gain elevation until it reaches its highest point in an unnamed pass in the middle of Lassen Peak and Bumpass Mountain. The road then descends and heads northwest, finally terminating at Interstate 5 at the foot of Mount Shasta at around 3,600 ft (1,100 m). (1,100 m).[2][3]
The portion of SR 89 that runs through Lassen Volcanic National Park is closed in winter due to very heavy snowfall and snowpack. When it is open, a park fee is charged. At the other park entrance in the northwest corner, SR 89 temporarily ends, but one can continue along SR 44 to the northeast. SR 89 resumes northward approximately 13 miles (21 km) later.
From the junction with SR 147, through the park and including the gap on SR 44, to its terminus at I-5, SR 89 is part of the Volcanic Legacy Scenic Byway, a National Scenic Byway.
The section of SR 89 from SR 70 north to Crescent Mills was built over the abandoned railway bed of the Indian Valley Railroad.
The section of SR 89 from SR 88 north to US 50 is co-signed as US 50 Alternate for use as a detour for when US 50 closes.
The southernmost section of State Route 89 over Monitor Pass is also closed in winter due to snow accumulation. [1]
This route is part of the California Freeway and Expressway System[4] and is eligible for the State Scenic Highway System[5].

[edit] Route description
One point of interest along California State Route 89 includes the Pony Express remount station in Woodfords, (that was in use for only five weeks (California Historical Landmark #805), the Lake Tahoe Outlet Gates (CHL #797) in Tahoe City (Control of these gates was the source of the two-decade "Tahoe Water War" between lakeshore owners and downstream Truckee River water users), Plumas-Eureka State Park (containing a well-preserved Johnsville, a well-preserved '49er town, and Pioneer Ski Area, the first sport skiing area in the Western hemisphere), Lake Almanor and Lassen Volanic National Park.
Many other points of interest, including Brokeoff Mountain, Sulphur Works, Emerald Lake, Lake Helen, Bumpass Hell, Lassen Peak and Summit Lake are also located on this highway.
