Crater Lake National Park

The rehabilitation project for both West Rim & East Rim Drives at CLNP included reconstruction of the entire West Rim Drive and a pavement overlay of East Rim Drive from the North Junction to the Cleetwood Cove Trail parking area; plus mitigation of selected sites on the East Rim Drive. The typical proposed roadway consisted of a 22’ to 24’ wide paved road, with flattened side slopes (fore slope of 4H:1V). In order to provide proper drainage, localized sections of the side slopes of the road needed to be steepened (fore slope of 3H:1V).
