Lassen Volcanic National Park Highway Historic District
Also known as: NPS Route 1; Lassen Loop Highway; Lassen Peak Highway; State Route 89
Why it's listed
Lassen Volcanic National Park Highway is a 29.86-mile road linking the park's southwest and northwest entrances. It climbs from 6,646 feet to 8,511 feet near Lassen Peak, then descends toward Manzanita Lake, crossing geothermal areas, subalpine forests, meadows and lava fields. National Park Service engineers laid out the alignment in 1924-25 to show automobile tourists the park's most scenic and geologically interesting places, and the Bureau of Public Roads took over much of the construction after a 1926 agreement. Civilian Conservation Corps projects continued until 1941, and paving and widening followed between 1948 and 1951. Scenic pullouts, masonry culvert headwalls, bridge culverts, entrance pylons and the northwest entrance station were built from native materials to blend with the surroundings. Grades never exceed six percent. The road is listed as an intact early example of national park road design, and it remains the main way visitors experience the park.
Significance in brief: The nomination argues the highway is an intact example of early National Park Service road design. Its alignment, overlooks, culvert headwalls, bridge culverts, entrance pylons and northwest entrance station use native materials and naturalistic design to blend with the volcanic landscape. It reflects major construction by the National Park Service, the Bureau of Public Roads and the Civilian Conservation Corps.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
