This 1935 Hagstrom's map shows an expanded area of what was shown above with two Toll Gates also shown. The first is west of Colonial Springs Road at Huntington Road/Route 110, (lower left of the picture) and the second is at Deer Park Road in the upper right hand corner.
The map on the left is from the 1952 Hagstram Atlas of
Suffolk County and shows the Motor Parkway running southeast of Colonial
Springs Road/East Neck Road and then back north to cross East Neck Road. The Google map on the right shows in blue
where I believe the roadway existed. Interestingly, the road heading south
that is roughly where the Motor Parkway ran is today named Ridge Road.
My next page (and more to come) will detail the Motor Parkway as it headed back north into Half Hollow Hills and Dix Hills.
