HUNT completed preliminary and final design, and Construction Inspection for the replacement of this bridge under the Federally Funded Locally Administered (FFLA) procedures.  The existing structurally deficient steel girder and concrete deck bridge spanning Catharine Creek, a locally active trout stream. 

Complicating the replacement was the integration of the foundation of the adjacent Mill Building, known as Journeys End along the Catharine Valley Trail. This building foundation was tied in to the original bridge foundation, and after design approval, alternative evaluation made it clear rehabilitation would not be an option, addressing this foundation became a significant design challenge.

HUNT’s solution to this challenge was a micro-pile supported foundation installed with continuous vibration monitors to protect the existing structure. The vibration monitoring plan developed by HUNT and their geotechnical consultants became a model for other vibration monitoring projects in the region.  The micro-pile approach proved very effective, evidence by higher vibration monitoring results from the occupants slamming doors than the pile installation operation.

Right of way acquisition was also a key element of the project as the nine effected parcels included abandoned properties, church properties municipal jurisdiction transfer and tradition private acquisitions and easements.  The project also required clearing of an encroachment to remove a porch improperly construction in the road right of way.
