Update 2020: WHTM has posted a retrospective at https://www.abc27.com/news/local/harr.... When I discovered this I planned to take this video down, but then I noticed they didn't include all the footage. Please visit their page too.

On January 22, 1996, sections of the Walnut Street Bridge in Harrisburg, PA are carried away by flood waters and ice floes after the North American Blizzard of 1996 and subsequent thaw and rain. It crumples under the Market Street Bridge (3:05), the next bridge downstream in the Susquehanna.

This video appears to have been shot from around 27 Cumberland Rd, Lemoyne, PA 17043, on the West Shore, by my estimation. https://goo.gl/maps/VHJWw
