Biographical / Historical

The Portage Lake Lift Bridge is a bridge that connects the cities of Hancock and Houghton. The first bridge over Portage Lake was a wooden swing bridge built in 1875. A railroad level was added to the bridge in 1891. In 1897, the wooden swing bridge was replaced with an iron swing bridge. This bridge was destroyed in 1905 when a steamer collided with it, and a new iron swing bridge was built. It remained in use until 1959, when the current lift bridge went into operation.

This collection guide includes collections from member organizations of UPLINK (the Upper Peninsula Digital Network) as well as the Central Upper Peninsula and Northern Michigan University Archives. UPLINK collections document the history of the Upper Peninsula broadly, while the Central UP & NMU Archives focuses on such topics as Northern Michigan University history, the local iron mining industry, and the politics, economics, religion, environment, and culture of the Central Upper Peninsula region.

These finding aids will give you an overview of the contents and context of each collection. Finding aids only exist for collections that each organization has shared with UPLINK or (in the case of the NMU Archives) for processed collections. For a more comprehensive list of collections that might help with your research, please contact the relevant heritage organization(s) directly.
