Memorial Highway", honoring the US Army division that lost 992 soldiers during the Italian Campaign in World War II. SR 89 runs concurrently with I-80 eastbound briefly before exiting to the north and continuing through the city of Truckee and passing near Prosser Creek Reservoir outside of the city limits. SR 89 continues through Hobart Mills before crossing into Sierra County and continuing northwest to Randolph and Sierraville, where it shares a wrong-way concurrency with SR 49 through the town of Sattley; they then intersect CR A23 before SR 89 splits off to the northwest. SR 89 continues through Calpine before crossing into Plumas County. SR 89 continues through Clio and Graeagle before running concurrently with SR 70 through Plumas National Forest, passing through Blairsden, Feather River Inn, Cromberg, Spring Garden, Massack (where SR 70 and 89 have a rest area), East Quincy, and the city of Quincy. SR 70 and SR 89 continue north through Keddie before SR 89 splits off to the north and passes through Indian Falls, Crescent Mills, Greenville, and Canyondam. The section of SR 89 from SR 70 north to Crescent Mills was built over the abandoned railway bed of the Indian Valley Railroad. SR 89 intersects with the south end of SR 147 before paralleling the southern shore of Lake Almanor and running concurrently with SR 36 westbound, crossing into Tehama County and Lassen National Forest. SR 36 and SR 89 intersect the northern terminus of SR 32 and SR 172 before SR 36 splits off to the west and SR 89 enters Lassen Volcanic National Park. The SR 89 state designation officially does not run through the national park, and this segment is directly under the park's jurisdiction instead of Caltrans. When it is open, a park fee is charged. The segment through the park is typically closed during the winter due to very heavy snowfall and snowpack. Outside the other park entrance in the northwest corner in Shasta County, SR 89 forms a concurrency with SR 44, heading northeast to Old Station. After splitting from SR 44 at Old Station, SR 89 continues north through Hat Creek and Doyles Corner before intersecting SR 299. The highway passes through Four Corners and Cayton before intersecting CR A19 and crossing into Siskiyou County. SR 89 briefly passes through the Klamath National Forest and Bartle and McCloud before coming to an interchange with I-5. SR
