CATTARAUGUS COUNTY BRIDGE MAINTENANCE
HUNT provided scoping, design approval, contract document preparation, construction administration, and inspection for a federally funded Bridge Maintenance Program that included bridge painting, bridge washing, and deck sealing on over 240 structures. This project was unique in that it was the first project to utilize federal funding to advance maintenance activities such as these on multiple structures. The initiative was developed by the County and the NYSDOT Region 5 and has been a highly successful model for other local project sponsors to use for funding maintenance activities.
In addition to the Bridge Maintenance Program, HUNT has been involved in the design and construction of multiple bridge structures in Cattaraugus County. Several of those structures are described below.
Carrolton #31 Bridge Replacement
This federally funded locally administered project located in the Village of Limestone was administered by Cattaraugus County for the Town of Carrollton. HUNT provided preliminary design, final design, and construction inspection for the replacement of this aging bridge, originally built in 1935.
The Town was adamant about maintaining traffic on-site during construction. A cost benefit analysis showed that the on-site detour was warranted and could be paid for under the federal guidelines.
The bridge was replaced with a precast rigid frame (“three sided”) structure on the existing alignment with a single span of 25.6 feet, 45 feet wide including two travel lanes, shoulders, and sidewalks. The structure is founded on an invert slab that is recessed to allow for a native stream bed in conformance with current environmental goals.
The village setting warranted some aesthetic considerations, the use of Texas Barrier and an architectural lighting concept provided the appropriate detail for the context.

County Route 27/Haskill Road Rehabilitation
This highway rehabilitation project was locally funded and proposed to rehabilitate a 1.4 mile section of a Major Rural Collector which connects Olean to Cuba in Cattaraugus County. The project team reviewed existing roadway maintenance records and took pavement cores to evaluate the condition of the roadway structure. From the studies and evaluations five different pavement treatments were proposed for the project from a simple mill and resurface to full depth re-construction. The existing roadway did not have paved shoulders which was a safety concern due to the heavy truck traffic the traversed the road. This left very little room for pedestrians and bicyclists. Four foot paved shoulders were proposed for the project. There was a significant horizontal curve that was improved as part of the project.
Other project features were the replacement of five cross culverts including on concrete box culvert which was replaced utilizing a temporary traffic signal maintaining traffic on site due to the significant use of the corridor. The cost of the project was $2.9 million, and it was constructed during the summer of 2013.
HUNT was then retained to complete the design for Phase IV of the project which will replaced a 3-span concrete adjacent box beam bridge with a single-span steel girder structure. The existing structure was used to maintain traffic while the new bridge was being constructed, as there were not acceptable detour options available. Nearly 1/2 mile of approach work was rebuilt when the project was completed in 2016.
Otto Bridge No. 14
HUNT was hired to provide design services after flooding in August of 2009 washed out the bridge that carried North Otto Road over Waterman Brook in the Town of Otto, Cattaraugus County.
The new bridge is a 50-foot span precast concrete voided slab structure on concrete abutments founded on steel h-piles.
Minor improvements to the horizontal and vertical alignments helped to increase the safety of the road as well as improving the hydraulics of the bridge. Appropriately-sized rip-rap was provided to prevent future scour problems.
HUNT completed preliminary and final design, along with construction inspection to replace the bridge using FEMA funding. It was opened to traffic in late 2010.
