Testing of Cos Cob bridge may cause Metro-North delays
Metro-North says testing of the 115-year-old Cos Cob bridge Monday morning could cause some train delays on the New Haven Line.
The testing that is scheduled to begin 10 a.m., may require periodic openings.
“These could cause delays of 20-25 minutes,” Metro-North says in an advisory. “Thank you for your patience.”
The testing is related to ongoing repair work on the 19th century bridge that includes replacement of timber ties/miter rail and steel repair on Track 3.
The Cos Cob Bridge over the Mianus River was completed in 1904. It is the busiest moveable bridge on the New Haven Line, which carries nearly 40 million passengers annually.
The bridge has become stuck before. There were several incidents in late 2016 because a dredging project in the Mianus River required the bridge to be open more often. The problem was the mechanism locking the bridge for trains to cross also failed to operate correctly
The four largest rail bridges in Fairfield County -- the Cos Cob Bridge in Greenwich, the Saugatuck River Bridge in Westport, the Norwalk Walk Bridge and the Devon Bridge over the Housatonic River -- are remnants of another time.
Only Norwalk’s Walk Bridge, built in 1896, is being replaced.
