This bill designates the bridge over Route 101 in the city of Keene, known as South Bridge, as the "Charles Redfern Bridge." This naming is formalized under RSA 4:43, which allows for the naming of public structures.

Additionally, the bill stipulates that the costs associated with the design, construction, maintenance, and installation of signage or markers related to the bridge's new name will not be borne by the state. Instead, these costs will be managed separately, with all signage designs requiring approval from the Department of Transportation. The act is set to take effect immediately upon its passage, which is noted as May 14, 2025.
