WATERBURY — Ongoing work to widen I-84 through Waterbury is currently ten months ahead of schedule, Governor Malloy announced at a press conference Friday.  The project is adding an additional lane of travel in each direction.

“Now 10 months ahead of schedule, the DOT – along with its contractors and construction crews – continue to make progress.  When the project is finally completed, this will make a big difference to not just the Waterbury area, but to residents statewide.  As we enter new phases of the project, we’re continuing to deliver results for residents,” Governor Malloy said.  “We all agree that for too many decades, our state did not make the investments needed to ensure we maintained a modernized transportation system.  Through projects like this one, we are finally taking bold steps towards making a best-in-class transportation system a reality.  The growth of our economy depends on these kinds of major upgrades, and our residents deserve nothing less than an efficient, upgraded, and renewed infrastructure that advances progress, mitigates congestion, and creates jobs.”

The I-84 Waterbury Project has created over 250 jobs in the Waterbury area, a statement from Gov. Malloy’s office said. .

“While we continue to meet our construction milestones for the I-84 Waterbury Project, we’re definitely seeing real progress every day.  And by sustaining this pace of work, and with the cooperation of the weather, we anticipate remaining ahead of schedule and on budget,” John S. Dunham, I-84 Waterbury District Engineer, said.  “We appreciate the patience of residents, business owners, commuters and travelers, and thank the public for their support and positive feedback.”

The project includes:

  • Widening and addition of a third travel lane and full width shoulders in each direction
  • Safety improvements from Washington Street, east to Pierpont Road in Waterbury
  • Realignment of the interstate roadway to eliminate the existing “S” curve alignment
  • Interchange ramp reconfiguration
  • State and local road construction
  • Relocation of the Mad River and Beaver Pond Brook
  • Construction/replacement of eight highway bridges (four over watercourses)
  • One pedestrian crossing over the Mad River
  • Seven culverts
  • 20 retaining walls
  • Sanitary sewer relocation
  • The replacement and upgrade of traffic signals, new highway illumination, new signs and pavement markings and replacing or relocating, potable water and other public utilities.

The project started construction on March 30, 2015 and is scheduled for completion in June 2020.
