Chicago IL / Bridgeport drawbridge
* Significance: The Chicago & Alton Railroad bridge was the first Page bascule erected for railroad use. Patented by John W. Page, a Chicago engineer, the Page bascule was not as extensively built as other patented systems such as the Strauss-Trunion bascule.
This Chicago & Alton bridge may be the only one of its kind in existence.
* Survey number: HAER IL-104
* Building/structure dates: 1906 Initial Construction

Notice the "Stein Hall Mfg Co. - Gums" sign on the left. I've never heard of this company before, but apparently they made various food and starch-based products in the early 20th Century.
