Area Around 125 th Street - Broadway Subway Station Manhattan
125th Street - Broadway station in Manhattan is indicated by a red square. The station is elevated while the other stations in the area are underground. The "Manhattan Valley" viaduct was contructed by the Interborough Rapid Transit Company (IRT) due to the great change of elevations near 125 th Street. You can see this in the above map by the change of colors and the contour lines. You can clearly see that "Manhattan Valley" runs diagonally across Broadway with 125th Street inside it. Only street grid for the CD shown. In the map below, contour lines are shown. The purple underlined numbers is the elevation in feet. Notice that east of Broadway, West 125th Street is located in a relatively flat valley with few contour lines.
