“A lot of the congestion on Mill Plain Road is bypass traffic,” said Neil Patel, principal engineer for the costly and long-term I-84 improvement project. “With the improvements of the dynamic lane, we’ll see a (reduction) of that (bypass) traffic.” By “dynamic lane” Patel is referring to a $200 million plan that could begin construction in early 2028 to allow driving on the inside shoulder of I-84 between exits 3 and 7 during highway backups. The shoulder lane, which would revert to a shoulder once the congestion cleared up, is among a handful of short-term projects to ease highway backups and related traffic jams at city exits that will be discussed during a meeting on Thursday in Danbury. The DOT’s overall plan to straighten and widen I-84 is still a decade away from beginning construction and is expected to cost between $3 billion and $4 billion. The expected completion date is in the 2040s.
