White Woods Road Bridge
Replacement of the White Woods Road Bridge, Litchfield, CT
Cardinal Engineering provided all engineering services for the replacement of the White Woods Road Bridge, which included survey, bridge design, full-time contract administration and resident engineering services.
The major concern with the bridge, constructed in 1963, was the scour and undermining of both abutments. Structural stability analysis determined that the abutments were unstable under design scour conditions. After reviewing three alternatives, it was determined that the bridge replacement was the most cost-effective solution.
This project is located within the White Memorial Nature Preserve Habitat where several endangered bird species reside, therefore the construction season was limited and required an accelerated bridge construction method. The design consisted of pre-stressed concrete box beam superstructure on integral abutments supported by a pile foundation, which greatly simplified construction to meet a shortened schedule for reopening the bridge to traffic, while reducing construction costs and environmental impacts.
This project was funded under the Federal Local Bridge Program. Construction was completed in December 2017.
