Update August 2nd, 2017: WFLHD and Park County completed the 95% Review in July 2018 along with acquiring temporary construction easements for the project.  Coordination activities are underway with the utility companies in preparation for project construction. Solicitation is scheduled for Fall 2017 and project construction remains on schedule for spring of 2018.  The scope of work for the Carbella Bridge has been modified to include deck replacement along with the already programed repairs. 

Update June 12th, 2017:  Coordination activities are underway with power and communication utility companies in preparation for the project construction, which remains on schedule for the spring of 2018.  Park County is currently working with adjacent landowners for temporary construction easement agreements.   FHWA issued a Categorical Exclusion NEPA determination for the project and completed 70% Design Review in mid-April 2017.   

Portions of this project – including the Tom Miner Bridge, 30 NBI rating - were prioritized in the 2012 Park County Capital Improvements Bridge Plan.  The Tom Miner Creek Bridge is experiencing significant undermining of the abutments and does not meet current standards for lane widths and barrier protection and conveyance.  The historic Carbella Bridge is not structurally deficient but has significant approach and departure deficiencies that result in a 41.3 NBI rating.  Rock Creek (South) Bridge, 37.5 NBI rating, provides the only alternative access to Tom Miner Creek Road and basin area for highway loads, as well as the only alternative detour to the area if the Carbella Bridge is closed.  Rock Creek (South) Bridge has the following deficiencies – failure of southwest wingwall/abutment which is anchored with steel cables under the roadway; vertical fracture in the northwest wingwall; erosion between the roadway and northeast abutment; and, undermined abutments on the entire south side and the northwest side.  Tom Miner Creek Road/Old Yellowstone Trail Road is comprised of gravel surfacing and has an estimated SADT of 244 and is maintained by Park County for the first six miles.  The remaining 5.5 miles to the Tom Miner Campground area and trailheads are maintained by the United States Forest Service.  

The project will improve access to the areas served by Tom Miner Creek Road and Old Yellowstone Trail South Road, both of which traverse near, to and through Custer Gallatin National Forest and the Tom Creek Basin area – with several tributaries flowing into the Yellowstone River.  Primary project activities will include bridge rehabilitation, approach and departure improvements, bridge replacement, minor ditch reconstruction and surfacing improvements.  Park County is able to provide a 13.42% cash and in-kind match for the project.
