I’m making A parkway with very short ramps witch will be at every other or every third street, this may sound like to much but the parkway will be in a rural area with not very many roads. Allso The ramps may be short but the parkway is supposed to be old and will not be up to freeway standards.

I’ve came up with my highway system 1 or 2 digit H roads are limited access highways B roads are short and parts are limited access but others are not and 3 digit H roads are Connectors. R roads are major roads and roads without a prefix are old roads List of H roads: H1 Border to H2 H2 border to Stamford H5 not done H45 H53 to above Stamford H53 H2 to eastward H102 loops around city B roads B1 B2 R roads R17 R34 R54 Old roads 144

I am working on a large city based on Chicago IL, New York NY and Stamford CT with 45 streets that are numbered and 16 Avenues numbered that will be a huge city when I’m done, I’m all so working on a highway system for that part of the country.
