This bill designates the bridge over Route 101 in the city of Keene, currently known as South Bridge, as the "Charles Redfern Bridge." This naming is established 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, and any signage must receive approval from the Department of Transportation. The bill is set to take effect immediately upon its passage, which is noted as May 14, 2025.
