New York Roads - Long Island Renumbering

Renumbering the State of Long Island

The rules of the game:
1) New York maintains its route numbering as current, except NY 25 no longer ends on the Manhattan side of the Queensboro Bridge. (Unless they really want it to.)
2) Interstate highways will not be changed. No extension of US 46 or 22. Named Parkways will disappear because they're a New York phenomenon.
3) No new miles of road may be built. Freeways may not be upgraded from existing surface roads (e.g. changing NY 347 to I-595), but surface roads may be upgraded from town/county maintenance to state maintenance and standards.
4) There are not all that many state highways. Therefore, there will be no downgrading (Interstate to state, state to county, county to town, even signed to unsigned). In fact, unsigned highways (including reference routes) will be signed just to add to the network. There are no route concurrencies, because again, there are plenty of available numbers.
5) Just for a larf, odd numbers go E-W, evens go N-S, and numbers increase from the northwest corner. 5's and 0's are the longest, 1's/9's and 4's/6's are minor routes, and 3's/7's and 2's/8's are reserved because there's plenty of space for them. Freeways, expressways, and parkways are three-digit routes beginning in "1" that fall roughly in the same grid as the surface routes (1-2 digits).

My proposed new LI State Route shield, using the old county route colors that are also Long Island's official colors.
