Replacement of Bridge No. 04730 – Gurleyville Road over Fenton River

This Connecticut Department of Transportation (CTDOT) project (No. 0077-0249) includes design, bid phase services, and services during construction for the replacement of Bridge No. 04730 carrying Gurleyville Road over Fenton River in the Town of Mansfield, Connecticut. The bridge is located approximately 1.3 miles east of US Route 195 and 0.25 miles west of the intersection with Codfish Falls Road and Chaffeeville Road. The 23’-7” wide roadway over the bridge is classified as a Rural Minor Collector with an Average Daily Traffic (ADT) of 1,022 vehicles per day with 5% truck traffic (August 2023); the roadway width is substandard. The bridge superstructure is comprised of eight 1’-9” deep prestressed concrete deck units supported by stone masonry abutments with a concrete bridge seat founded on an unknown footing. The bridge superstructure was originally constructed in 1970.

The proposed 53’-9” long replacement structure will carry a roadway width of 30′-0″, accommodating (2) 10′-0″ travel lanes and (2) 5’-0” wide bike lanes and meeting FHWA and State standards. The roadway will be reconstructed approximately 300 feet west and 300 feet east of the bridge. The existing horizontal alignment will be shifted approximately 6.5’ to the north while the existing roadway will be raised by up to 1.5’. Roadway drainage improvements are also proposed as part of this project. Traffic will be detoured during construction through an 8.7-mile detour route.
