Onawa is an unincorporated community and populated place in the U.S. state of Maine. Onawa is located next to Lake Onawa and lay along the former route of the International Railway of Maine. In 1919, a major train wreck occurred two miles west of the Onawa railway stop.[1]
The Onawa Trestle was built in 1930 for the Canadian Pacific Railway. From 1942 until the conclusion of World War II in 1945, the all-Black 366th Infantry Regiment guarded the remote bridge.[2]
