The road parallels the scenic Eel River, and connects the small towns Phillipsville, Miranda, Myers Flat, Weott, Englewood, Redcrest and Pepperwood.

[6] Though not the oldest redwood in the forest, this large tree is at age millennium, and is currently around 250 ft (76 m) tall, though originally it was much taller.

It has survived not only the ravages of time but also a 1908 attempt at logging, the 1964 flood of the area, and a direct lightning strike which removed the top 45 feet (14 m) of the tree (making its original height close to 300 ft).

Located in the northern half of the Avenue, The Immortal Tree is easy to find, and has a large gift shop and parking area situated in front of it.

The front door and windows are clearly visible to passersby, and the rest of the house adjoins the rear of the tree in a more traditional style.

It carves deep canyons down great mountains, through flat valleys, and past ancient redwood forests.

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.
