The I-84 Waterbury Widening Project involved 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 was the realignment of the interstate roadway in the vicinity of Harpers Ferry Road, to eliminate the 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, were reconstructed:

  • Hamilton Avenue
  • Harpers Ferry Road
  • Scott Road
  • Plank Road
  • Reidville Drive
  • Plank Road East
  • East Main Street

The project included the construction / replacement of eight highway bridges (four over watercourses), one pedestrian crossing over the Mad River, seven culverts (five within the Beaver Pond Brook, one within East Mountain Brook, and one within the Mad River), and 20 retaining walls. It included replacing and upgrading traffic signals, new highway illumination, new signs and pavement markings, and replacing or relocating sanitary sewer, potable water and other public utilities.
