Greetings and welcome to the forum!
It doesn't matter too much what they
were going to call the street. It
will be called Louis J Robichaud St, which is a fitting name.
The only incongruous thing is that the street will currently only be a stub off of Mapleton Rd. The name will make more sense when it connects through to the Crowley Farm Rd and on to U de M.
I wonder how many years it will take to extend the street the whole way?
