Located roughly near the geographic center of the state, the merger of three highways — Interstates 91 and 691, as well as state Route 15 — forms a sprawling interchange that carries an average of 260,000 vehicles every day. Tuesday’s groundbreaking was largely ceremonial, as work on the $500 million reconstruction project actually began late last year. Officials including Gov. Ned Lamont, Federal Highway Administrator Shailen Bhatt and Connecticut Department of Transportation Commissioner Garrett Eucalitto each tossed shovels full of dirt in the air to applause, while unionized workers employed on the project looked on. Actual work on the project is broken down into three phases, of which the first two are underway. The third and final phase is in design, with a scheduled completion date in 2029.
