Murray Baker Bridge, Peoria, Illinois. (Previously misidentified as the McCluggage Bridge.)

According to HistoricPeoria.com:
"Thanks to businessman Murray Morrison Baker, Caterpillar is headquartered in Peoria. In 1909, Baker convinced Holt Manufacturing Co. to open a factory here. Holt merged with C.L. Best Gas Tractor Co. in 1925 to become Caterpillar Tractor Company. Baker became vice president and director of sales for the newly formed company and later served on Cat’s board of directors."

Later he had a bridge named after him.
