The Second Avenue Subway runs from 125th Street in Harlem to Hanover Square in Lower Manhattan, with a track connection to the existing 63rd Street and Broadway Lines which will allow for direct service from East Harlem and the Upper East Side to West Midtown via the Broadway express tracks (16 new stations).

Sub Title
Project Overview:
The Second Avenue Subway line runs from 125th Street in Harlem to Hanover Square in Lower Manhattan, with a track connection to the existing 63rd Street and Broadway Lines which will allow for direct service from East Harlem and the Upper East Side to West Midtown via the Broadway Express tracks. Sixteen new stations were constructed to serve the new lines.
Project Objectives:
Two of the three existing Second Avenue rail lines were taken down over the years to due to debunk plans to expand the line. This history of planning, preliminary construction, and abandonment left only one line to serve the East Side of Manhattan’s ever increasing population. Unfortunately, for the riders of this last line, the area was already operating beyond capacity. The current Second Avenue Subway project is underway in order to remedy the existing transportation issues.
