There's a big rebuild of the recent big rebuild of I-40 in Southern Durham County. And as a result, commuters have been urged to use alternate routes. One of the 'detours' is along NC 147, aka The Durham Freeway. Using NC 147 is all well and good for a detour or even an alternate route for INTERSTATE 40, but US 40?. Sure, if the entire states of Maryland and Virginia were under construction. (And to some...both states are). Photo credit to Craig Zeni who came across this sign on April 18th.
...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
