I-84 Waterbury

The purpose of this project is to improve safety, operation and highway capacity on Interstate 84 (I-84) in the City of Waterbury. Currently, the section of I-84 through the project limits experiences heavy traffic congestion due to high traffic volumes, steep topography, lack of roadway capacity, and design deficiencies in ramps and weave areas.

The implementation of the proposed project will improve traffic flow along I-84 and local nearby streets and reduce current and future traffic congestion along the mainline and the connection streets, ramp weaves, and accident rates. These traffic enhancements will result in improvements to air quality, noise, aesthetics, and the quality of life.

The I-84 Waterbury Project involves the widening (addition of a third travel lane and full width shoulders in each direction) and safety improvements to a 4.3 Km (2.7 miles) segment of Interstate 84 from Washington Street, east to Pierpont Road in the City of Waterbury. Included in this project are the realignment of the interstate roadway in the vicinity of Harpers Ferry Road (Interchange No. 24) to eliminate the existing substandard “S” curve alignment; interchange ramp reconfiguration; State and local road construction; and the relocation of the Mad River and Beaver Pond Brook.

As a result of the realignment of I-84 and the reconfiguration of the ramps, portions of the following State and local roads with intersections will be reconstructed:
•Hamilton Avenue
•Harpers Ferry Road
•Scott Road
•Plank Road
•Reidville Drive
•Plank Road East
•East Main Street
