Using Wider Interstate Signs for Highways with 3-Digit Numbers

The US Interstate Highway Authority created strict guidelines on how highway signs were to be created. Interstate signs were to have consistent numbers in fonts and sizes to provide clarity to users traveling at high speeds. Broadcast map designers might have a different purpose. Our original XPression Maps customers in the USA asked for the shield to stay the same size, and the numbers to shrink. That is not what the Interstate Highway team wanted, and some other customers agreed. Now, there is a way to use Open Street Maps and utilize wider shields, like it was intended.
