Certain Effects of Bridges on Transit Conditions

This paper is a study of the effect of the construction of important vehicular bridges on transit conditions in the adjacent communities. Although the primary object of building such structures is usually the accommodation of vehicular traffic, railway tracks are likely to be included, and the increased transportation facilities thus provided cause far-reaching changes in the trend of passenger traffic. In particular, the effect has been studied of the construction of the Brooklyn and Williamsburg Bridges on travel between the Boroughs of Manhattan and Brooklyn of the City of New York. As an example of the possible application of the conclusions drawn from that investigation, the situation created by the erection of the new Delaware River Bridge between Philadelphia, Pa., and Camden, N . J., has been considered. An analysis of traffic movement across the East River, New York, indicates that the existing transportation lines in New Jerscy should be extended across the new bridge into Philadelphia.
