The Connecticut Department of Transportation’s I-95 Interchange 74 Improvements Project in East Lyme, CT, involves the realignment and construction of new on- and off-ramps at Exit 74, along with the replacement of the I-95 Bridge over Route 161. These improvements are designed to enhance safety and traffic flow for motorists transitioning on and off the interstate. Manafort Brothers, Inc. was selected as the Prime Contractor to deliver this critical infrastructure project on one of the most heavily traveled sections of I-95.

The mainline highway work spans more than one mile and is being executed in six carefully planned stages. Manafort’s scope includes daily complex traffic control operations, extensive rock blasting and removal, large-scale earthwork, precast concrete retaining walls, soil nail walls, drainage and utility relocations, culvert extensions, wetland establishment, highway lighting, precast barrier installation, and paving. More than 300,000 cubic yards of earth and rock are being excavated to modify the vertical curvature of I-95—improving sightlines, roadway safety, and the vertical clearance at Bridge No. 250 over Route 161. Certain areas of the interstate require cuts and fills of up to 25 feet to accommodate the new roadway and bridge profile.
Manafort’s bridge scope includes the multi-stage demolition and reconstruction of I-95 Bridge No. 00250 over Route 161, ensuring continuous traffic operations throughout construction. The project also includes structural modifications to existing Bridge No. 0251 over Latimer Brook, requiring strict adherence to environmental protections and permitting requirements.
As Prime Contractor, Manafort has self-performed a majority of the work, including demolition, earthwork, substructure and superstructure concrete, drainage, and roadway construction. Manafort’s extensive heavy highway and bridge experience has positioned the project for safe, on-time, and on-budget delivery.
