Those ass-backwards highway naming conventions
Those ass-backwards highway naming conventions … π
The NY 9-suffixes violate the naming convention that New York uses for most state highways — east west highways are odd numbers like NY 5 or NY 7, while north-south highways are even numbers like NY 8, NY 10, NY 22, etc.
The US highways use the opposite system that New York uses, because our state is ass backwards at least when it comes to numbering highways. Virtually every other state uses the federal convention, not the New York convention for numbering highways.
US 2 and US 20 is are east-west highway, while US 9 and US 11 is a north-south highway. Interstate 90 is east-west while Interstate 87 is North South.
