Mt. Vernon New Haven Line Bridge Replacements

MTA Metro-North Railroad last week completed replacement of the 6th Avenue Bridge in downtown Mount Vernon, New York, a month ahead of schedule.

Work to replace the 126-year-old bridge — which carries traffic and pedestrians over Metro-North’s New Haven Line — began in March 2019.
