It spans the Saginaw River and connects Vermont Street (on the west side of the river) and Woodside Avenue (on the east side). It was built in 1986.[1] HistoryThe Liberty Bridge was built to replace the Third Street Bridge, a small swing bridge located just south of the Liberty Bridge connecting Midland and Third Streets. The Third Street Bridge was the first bridge built across the Saginaw River in Bay City. It was originally built as a wooden bridge in 1864 by the Bay City Bridge Company. Its superstructure was reconstructed with iron and steel in 1872.[2] On June 18, 1976, the swing span of the Third Street Bridge collapsed as it was being opened, forcing the bridge out of service permanently. It had been struck by a vessel the evening before. A debate ensued on where to build a replacement bridge. In order to receive federal funding, the new bridge was required to have four lanes and a four-lane bridge at the same site would have necessitated the demolition of some historic buildings. As a result, the Liberty Bridge was built just north of the old bridge site, connecting Woodside Avenue and Vermont Street.[3] {{-}}References1. ^1 {{cite web|title=Bridge department|publisher=Public Works Department, City of Bay City, Michigan|url=http://www.baycitymi.org/departments/public-works-department/bridge|accessdate=May 25, 2013|deadurl=yes|archiveurl=https://web.archive.org/web/20130612002928/http://baycitymi.org/departments/public-works-department/bridge|archivedate=June 12, 2013|df=}} 2. ^{{cite web|title=Third Street Bridge - 1890 Newspaper Accounts|url=http://bay-journal.com/bay/1he/writings/third-st-bridge1890s-tribune.html|website=Bay-Journal|accessdate=2 December 2015}} 3. ^{{cite news|last1=Younkman|first1=Tim|title=Bay City changed forever the day the Third Street Bridge broke|url=http://www.mlive.com/opinion/bay-city/index.ssf/2011/06/bay_city_changed_forever_the_d.html|accessdate=2 December 2015|agency=M Live|date=3 June 2011}} External links{{Commons category|Liberty Bridge (Bay City, Michigan)}}
