OLD LYME — Amtrak plans single-track operation across the Connecticut River rail bridge from November 2026 through November 2027 while crews work beside the existing structure, its project page says.
The restriction will accommodate piles, cofferdams and retaining walls near active tracks. Amtrak gives no precise cutover dates. Single-track operation is not a shutdown of all trains.
The Old Lyme–Old Saybrook crossing carries Amtrak, CTrail’s Shore Line East and freight trains. Its replacement will have two electrified tracks and new signals, power equipment and controls.
NBC Connecticut’s October 16 report describes the new movable span as an upcoming major installation. The station reports that it is being built for delivery by barge, followed in a later phase by moving trains to the new alignment and taking the old bridge out of service. Those are planned steps, not confirmation that the switch has occurred.
Amtrak estimates completion in 2031 and a 100-year design life. The new bridge’s 70-mph design maximum compares with 45 mph today; that does not establish a passenger timetable.
For boaters, NBC reports that clearance beneath the replacement will rise from 18 to 24 feet, allowing more vessels to pass without an opening. The station attributes recurring opening-and-closing reliability problems to the existing movable span.
