Officially called the Textile Memorial Bridge, it is also called the Moody Street Bridge; and because of its association with writer Jack Kerouac, called the Watermelon Man Bridge and just "Jack's Bridge."
Short-term repairs are being made as of this writing(November 2008.) Plans call for a new span to be built upstream. When completed, the historic span is slated for demolition.
A group has formed to save the span as a public space and bicycle and pedestrian crossway like Boston's Northern Avenue Bridge as well as a park like proposed plans for Northfield, Ma's Schell Memorial Bridge. The group wants it as a tribute to Kerouac as he crossed it daily as a child and used the bridge for a chapter of his novel Dr. Sax.
