Based on recent personal observations, it appears that NY 22's north end has been moved from the Quebec border at QC 219 and is now at US 11 in Mooers (pronounced "Moores"). Any remnants of NYSDOT signage has been removed between US 11 and QC 219, except for a bold button copy sign that greets you southbound just before the U.S. Customs station. There is also end signage on NY 22 northbound at US 11, I am told. However, there is nothing that shows this on the NYSDOT website. If anyone has more evidence of this, please respond.
...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere. But there's a reason for this - and it's because of the National Fire Protection Association (NFPA). This association has issued guidelines for color coding standards for fire hydrants. These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure. This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant. If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system. If a hydrant is RED - the hydrant is connected to a private system, typically a well. These are most common in rural or unincorporated areas
