The project begins near the intersection of Forest Road 40 and Forest Road 41. The project proceeds westerly along Forest 40 for approximately 2.8 kilometers (1.75 miles) to the junction of Forest Road 40 and Forest Road 45. The project then proceeds northerly along Forest Road 45 for a distance of 18.7 kilometers (11.6 miles) to the intersection with Oregon Highway 372 (Cascade Lakes Highway). The roadway system provides primary access to the Deschutes National Forest and connects the communities of Sunriver and LaPine with the Mount Bachelor ski area and other recreation sites on the National Forest.

The existing paved surface appears to be nearing the end of its design life. There are a number of localized areas which display the characteristics of load-related distress and frost heaves. Roadway travel lanes and shoulders are too narrow for current and future traffic volumes and bicycle use. The horizontal and vertical alignments are substandard over a significant portion of the length. There is inadequate sight distance and clear zone through out much of the project.

The proposed action for the project includes replacing the pavement structure, revising in part or in total the horizontal and vertical alignments to meet the American Association of State Highway and Transportation Officials (AASHTO) standards for a 90 kilometer per hour (55 miles per hour) design speed, restoring crown and superelevation, widening the roadway to include paved shoulders, rehabilitating an existing parking lot, construction of a new parking lot, relocating chain on/off areas, upgrading signing, guardrail and pavement markings to current Manual on Uniform Traffic Control Devices (MUTCD) standards and drainage improvements.
