Downtown Washington Street Bridge Replacement Project

Washington Street is an important thoroughfare through downtown Naperville. It is the only north‐south route in the City that crosses both the BNSF railway tracks and the West Branch of the DuPage River. Being such a vital corridor, Washington Street sees a considerable amount of traffic. In addition to vehicular traffic, Washington Street is host to a variety of small businesses and recreational areas including Fredenhagen Park and the Naperville Riverwalk.

At the center of downtown Naperville is the Washington Street bridge. Tens of thousands of vehicles traverse this bridge every single day. The structure, which is located between Aurora Avenue and Chicago Avenue, is more than 40 years old and it is in need of replacement due to its deteriorated condition. To extend its life span, the bridge has been load posted to restrict the size of vehicle that can use the bridge. The bridge is still adequate for passenger vehicles.
