Constructed in 1946, the existing structure is comprised of two simply supported spans with a reinforced concrete deck supported by 5 rolled steel beams resting on reinforced concrete abutments and a reinforced concrete pier wall. The existing substructure is founded on timber piles. The existing structure has a maximum span of 51 feet and has a 31-foot curb-to-curb width and a bituminous concrete overlay. The existing structure length is 107 feet. The average daily traffic (ADT) is approximately 29,600 vehicles per day (2020). Superstructure structural deficiencies have driven the need for replacement. Adjacent to the structure is the Quinnipiac River Trail frequently used by the public. The surrounding terrain also poses challenges to accessing the site to perform any work under the structure. Additionally, the high traffic volumes require a thoughtful approach to maintaining traffic all while allowing for the construction of the project. Various options may be investigated to address the structural deficiencies of the superstructure but the design team shall take the following into consideration in their design choice: geometric limits, geotechnical conditions, site constraints, traffic impacts, constructability, environmental impact, and economy. Substructure elements shall also be evaluated for potential remediation based on the permissible soil and foundation capacities and any added loads. Common superstructure options are steel and precast/prestressed concrete.
