Does anyone know the location of "Rio Grande" in Delaware Township? I have checked the book "Hunterdon County Place Names" by Phyllis B. D'Autrechy and the name was not listed. It was found in the Hunterdon Republican Newspaper dated August 20, 1874, on page 3, left column about mid-way down!: "The Board of Freeholders met at Sergeantsville on Tuesday of last week and after viewing the site, ordered a new bridge to be built at Rio Grande, in Delaware Township. It is to be an iron stringer bridge, the trusses to be enclosed with boards, which has proved to be the most economical method. The building of the bridge was placed in the hands of the following committee, viz: Capt. James Bird, W. B. Hockenbury, and Joseph Smith. The probable expense of its construction will be about $700." Thank you for any positive assistance. Regards, Bill
