The Length of the Long Island Motor Parkway
Ann: "What was the length of the Motor Parkway from Queens to Ronkonkoma?"
Ann, it is an excellent question with varying answers depending on the documents. Take a look.
Enjoy,
Howard
A Motor Parkway brochure/map noted "a comfortable drive on 45 miles of fine, fast private right of way, built exclusively for the use of motorists at a cost of over six million dollars."
The "Try the Long Island Motor Parkway" ad promoted "45 miles in length" where one could "speed all you desire-unmolested."

Comments
I noticed in the first photo, a snow plow plowing the Motor Parkway. From the stories that I have heard from the people who have lived on Long Island for many years, a snow plow was rarely, if ever, seen in those days. It is interesting that those in charge of the Motor Parkway made sure the road was cleared of snow.
