Interstate 84 – Waterbury, CT

Project Description:

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 Bever 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

The project also includes the construction / replacement of 8 highway bridges (4 over watercourses), one pedestrian crossing over the Mad River, 7 culverts (5 within the Beaver Pond Brook, 1 within East Mountain Brook, and 1 within the Mad River), and 20 retaining walls.
