In October 2006, the Ohio Department of Transportation District 10 was approached by the Ohio Department of Natural Resources (ODNR) and Friends of the Hocking Hills State Park (FOHHSP) to complete a study that would identify existing roadway conditions and recommended improvements along approximately one mile of SR 664 in the Old Man’s Cave area of Hocking Hills State Park.

Currently, SR 664 runs through the middle of the park, bisecting the main parking areas from the rest of the park.  ODNR and ODOT have recognized pedestrian safety issues when visitors cross SR 664, as many near misses and skid marks have been observed by park officials.

This study will look ahead and prepare for future increases in traffic and pedestrian activity due to park development plans.  This proactive approach will improve motorist and pedestrian safety and better integrate the roadway with the park, making it a more enjoyable experience for generations to come. By working collaboratively with ODNR and FOHHSP,  we will work together to protect the park’s natural features and setting by reducing the environmental impacts of the highway to the area.

This study involves Steps 1 through 4 of ODOT’s Project Development Process and will examine the existing conditions of the area, including roadway and environmental conditions.  A series of alternatives were presented to the public on June 25, 2007.  Based on comments along with engineering and environmental studies, the alternatives evaluation will be completed and a preferred alternative will be identified. The preferred alternative will then be announced to the stakeholders and the public.

February 7, 2011 Project Study Update

The Ohio Department of Transportation (ODOT) and the Ohio Department of Natural Resources (ODNR) propose to realign a segment of State Route 664 within the Hocking Hills State Park near Old Man’s Cave.  The 0.8 mile long project will protect the park’s sensitive resources and improve pedestrian safety at the popular tourist destination, by relocating the highway away from the natural gorge and visitor center.

The existing highway is immediately adjacent to the north rim of the Gorge and Old Man’s Cave.  The new two-lane highway will be positioned north of the existing parking lot, remaining within property owned by the State of Ohio (ODNR).  The realignment will include improvements to the intersections of Lodge Drive and Culp Road (Benton Township Road 251), as well as a new entrance to the Old Man’s Cave parking area.

 In collaboration with the ODNR Division of Parks & Recreation and Division of Forestry, the project has been developed to protect the sensitive resources and unique setting of the park.  The proposed roadway will require approximately 16 acres of new right-of-way and nearly 2.5 acres of temporary right-of-way from ODNR for the improvement of park facilities.  In exchange, the existing roadway will be removed and nearly 4 acres of right-of-way incorporated into the park setting.  The design includes measures to minimize the footprint of the project, plantings to restore the woodlands adjacent to the roadway and the creation of an inviting entrance to the Old Man’s Cave area.
