Illinois has less historic bridges than many of the states which surround it, except for Cook County and Chicago, including Chicago's unique collection of movable bridges. HistoricBridges.org is proud to offer the most extensive coverage of Cook County and Chicago bridges available on the Internet. Cook County has one of the largest numbers of historic bridges in the country. The remainder of of Illinois is noted for a variety of large-span riveted truss bridges over navigable waters, traditionally composed pin-connected truss bridges over smaller waterways, and small-scale concrete through girders. However preservation of bridges outside of Chicagoland is nearly nonexistant in Illinois, and many bridges are being demolished.
