I'm working on locational tools for the 1950 Census which will become online in April of 2022. We (stevemorse.org and volunteers) have already transcribed all 1/4 million ED definitions, and over 2,100 city street indexes from 1950 city maps. Our website received 2.25 million hits when the 1940 census came online.
The National Archives has put online over 8,000 1950 census maps but Grand Forks is not one of them. I'm looking for a circa 1950 to 1960 digitized street map that we can use for our street index to census district project.
Grand Forks had 26,836 people in 1950.
Any help would be appreciated.
