Project Description

This project is located at Crater Lake National Park near the town of Klamath Falls, Oregon. Known for its deep blue color and water clarity, Crater Lake is a popular destination year round with a variety of warm and cold weather activities. East Rim and West Rim Drives complete the classic tourist loop road around the crater of Crater Lake and is very popular with park visitors. East Rim Drive provides an opportunity for visitors to have a quieter experience and unique view points of the lake when West Rim Drive is heavily used as a through road by many visitors. East Rim Drive also provides access to numerous scenic overlooks, Pinnacles Road and adjacent trails, and Lost Creek Campground.

Background

The paving was originally completed on this section of East Rim Drive in 1960. The first 4.5 miles of East Rim Drive were rehabilitated in a 2015 2017 3R (Rehabilitate, Restore, and Resurface) / 4R (Reconstruction, Rehabilitate, Restore, and Resurface) construction project including West Rim Drive. Currently, the existing road portion of East Rim Drive from Cleetwood Trail parking area to the intersection of Munson Valley Road is in poor condition. Over time, multiple informal pullouts have developed along the road causing pavement edge damage. Loss of pavement edge has also occurred in many locations due to erosion of the roadway embankment slope and in some locations the roadway and shoulder have settled. The existing historic stone retaining walls and guardwalls have been subject to damage due to various causes including rock fall, snow plowing, and moisture intrusion.

Scope of Work

The scope of the project is to rehabilitate pavement on East Rim Drive from milepost (MP) 4.5 to MP 23.2, all turnouts, paved walkways, and viewpoints with a combination of pavement overlay and full depth 3R pavement rehabilitation. Rehabilitation will include repair of the road base, subgrade, and shoulder where necessary. Drainage improvements will be included as needed.
