The state's project to widen I-84 in the Waterbury area will be completed a year ahead of schedule, according to Gov. Dannel Malloy.
The $330 million project that began in 2015 included adding a third travel lane and full-width shoulders in each direction on the highway, as well as other safety improvements.
The project was expected to take five years to complete, but Malloy said Monday that the three eastbound lanes will open this week and the three westbound lanes will open mid-September -- a full year ahead of schedule.
"The I-84 widening project is transforming and revitalizing mobility in Waterbury, and supports our goal to make Connecticut's transportation infrastructure best-in-class," Malloy said.
Gov. Malloy cut a ribbon at a ceremony Monday to celebrate the announcement.
Once all of the lanes are open, crews will continue milling and paving along the highway. That process should be completed in the fall, according to Malloy's office.
The westbound on-ramp at Exit 25 and Plank Road East-Harpers Ferry Road intersection is expected to open in November.
