"On the road again"

[:D]Good Day My MRXR friends!!
I hope all went well for you this weekend. The "N"scale Highway dept. is ready to build the streets and highways for the "N"scale population on our layout,

What we want to know is, what would the (width) of a one -lane or four-lane street be in “N” scale. We are building present day era.
Thanks [8D]

one lane is about 12 feet . in N that’s 7/8"
