State begins I-84 widening project

A groundbreaking ceremony recently took place for the widening of a section of Interstate 84 in Connecticut.

The highway will be widened in Waterbury between the areas of Washington Street and Pierpont Road, which is essentially just east of the Brass City Mall eastward toward Cheshire/Southington.

The project will see the creation of an additional, third lane on the highway in each direction.

During the widening, two lanes will remain open at all times during morning and evening peak travel hours. The project is scheduled for completion in June 2020.

Lessen traffic congestion

Gov. Dannel P. Malloy said the project will decrease traffic congestion, improve traffic operations, and increase safety.

“Our economic growth is directly tied to our transportation system, and if we want to develop our state and meet the challenges of the 21st Century, we need a modernized, best-in-class infrastructure for our residents,” Malloy said.

“This project on I-84 in Waterbury is critical for the future development of this region of the state as we continue our efforts to keep Connecticut moving forward,” he said.

Shoulder lanes on right and left

The reconstructed section of I-84 will have a 12-foot-wide right shoulder, three 12-foot-wide travel lanes, and a 12-foot-wide left shoulder in each direction of travel, separated by a 10-foot wide concrete barrier section.

Additionally, a 12-foot auxiliary lane will be provided on I-84 westbound between the on-ramp from Harpers Ferry Road and the off-ramp to Hamilton Avenue.

Other improvements include the construction of a new frontage road on the north side of I-84, referred to as Plank Road East, which will be constructed parallel to I-84 between Scott Road and Harpers Ferry Road.

Improvements are also being completed on Hamilton Avenue, Harpers Ferry Road, Scott Road, Reidville Drive, Plank Road, Plank Road East and East Main Street.
