Delameter Road is the main collector connecting the Coal Creek, Eufaula Heights and West Longview communities with the City of Castle Rock. Several trucking companies use Delameter Road as a more direct route between Ocean Beach Highway (SR 4) to the west and I-5 to the east. Many other trucking companies use Delameter Road for timber hauling, rock hauling and farm-to-market purposes.
Delameter Road provides access for recreational users into adjacent timberlands. Recreational uses attract drivers that are unfamiliar with the roadway, increasing the importance of adequate safety features on the roadway.
Delameter Road has narrow shoulders. The project will widen the roadway to meet rural major collector standards. Sight distance is poor at vertical curves. Sight distance will be improved to meet standards for the design speed of 45 mph, by improving substandard vertical curves.
