WATERBURY, Conn. (AP) - Gov. Dannel P. Malloy says the widening of Interstate 84 in Waterbury is ahead of schedule.

The Democratic governor announced Friday the plan to expand the highway with an additional travel lane in each direction is currently 10 months ahead of schedule. The project started in March 2015 and is scheduled for completion in June 2020.

The wide-ranging project includes 20 retaining walls, realigning the roadway to eliminate the exiting "S'' curve, reconfiguring interchange ramps, relocating a sanitary sewer, a river and a brook.

John Dunham, the I-84 Waterbury district engineer, says the Department of Transportation is "seeing real progress every day."

State officials expect the project will remain ahead of schedule and on budget by sustaining the same pace of work and continued good weather.
