The Tappan Zee Bridge crosses one of the widest points of Hudson River, connecting the villages of South Nyack in Rockland County and Tarrytown in Westchester County. It is about 25 miles north of Midtown Manhattan, and Interstate 87 and Interstate 287 utilize it.
The completion of the Tappan Zee Bridge in 1955 connected the two river towns of Nyack and Tarrytown, which used to connect only by a 30-minute ferry ride. After its completion, the bridge serves as one of the primary crossings north of New York City and carries much of the traffic between the points west of the Hudson and southern New England. In 2008, New York State officials announced the plan to replace the Tappan Zee Bridge. As of 2015, construction of the replacement bridge takes place a few meters to the north of the old bridge.
