Chaffee County Road 300 (CR300) provides access to the Arkansas River, the Browns Canyon National Monument, and to the Ruby Mountain Campground. There is a mix of traffic including school buses with trailers (rafting company transport), RVs, passenger vehicles, ATVs, and motorcycles.
This 0.10-mile section of CR 300 is gravel surfaced. The typical width is 19-22 feet, with the exception of a short narrow 12-foot section (the Narrows) located at the crest of a vertical curve in the middle of a horizontal curve. This section is bordered by a rock-cut on the north and the Arkansas River on the south. The current posted speed is 15 mph. The Narrows has deficient sight distance and inadequate geometry due to the proximity of the rock-cut to the edge of the roadway, making it difficult for traffic to pass safely. A traffic signal was installed by Chaffee County to facilitate one-way traffic through this section, but it continues to be vandalized and is currently inoperable.
The scope of this project is to widen the 0.10 miles of the existing roadway to a consistent 11-foot wide gravel surface, provide geometry and site distance for 20 mph speed design, improve drainage and improve safety by adding guardrail where necessary.
