Prior to development, Crooked Run Road had been used to access two intersecting roads, and the redesigned road would follow the same path. Starting at its intersection with NFSR 204, the new road would continue south for 2.1 miles to its intersection with NFSR 3018. The USFS proposed to redevelop Crooked Run Road to create easier access to both NFSR 204 and NFSR 3018 and to meet a C3 Road Management objective.

Alpha and Omega Group created horizontal and vertical alignment designs based on the AASHTO Guidelines for Geometric Design of Very Low-Volume Local Roads. The gravel roadway was designed as a 12 foot wide crowned road with one-foot shoulders. We decided on a normal, four percent crown to provide sustainable drainage and set the maximum grade for the vertical alignment at eight percent. The design also included 10-foot turnout lanes approximately every 1,000 feet to accommodate two-way traffic.

In addition to the horizontal and vertical alignments, A&O’s services included storm drainage design, permitting, erosion control plans, traffic control plans, and bid schedule. We also developed an engineer’s estimate of probable cost and developed supplemental specifications.
