The proposed project is not a major road replacement with associated re-routing, etc. The proposed project is being considered to address deficiencies in the condition of the road and safety concerns. The current pavement is aged in many locations, which has led to surface cracks, rutting, buckling, and unraveling of the pavement edge. Years of chip-seal patches with no road base layer, along with increased heavy truck traffic due to housing construction on private property, have impacted the road surface to an unacceptable and potentially unsafe level.
The width of the Kolob Terrace Road is currently from 19 to 22 feet. Improving the safety and maintenance of Kolob Terrace Road requires increasing the width of the road to the extent practical. A 22-foot pavement width with no grade change is proposed for the south section of the road. However, because of the narrow road bench from the base of Maloney Hill through the Black Canyon to the northern end of the project, the park is proposing to maintain a 20-foot pavement width for this section. In addition, a number of site-specific repairs are proposed to address subgrade failure, drainage improvements, poor sight distance, and closure or improvement of several informal pullouts. Curve widening and other improvements are proposed for the Smith Mesa Curve, Maloney Hill Switchback, and Wildcat Canyon Trailhead Switchback. The proposed project would be completed as soon as funding becomes available, and construction is expected to take one year.
