Why route name instead of route number
I live near ythe InterCounty Connector in Maryland that is the name of the road (it is a toll road with electronic toll collection only). It is signed as TOLL MD-200 only. No mention of the name on any signs. With some exceptions (Garden State Parkway and New Jersey Turnpike (ExitS 1 to 6 only are two) freeways and expressways in the U.S. should be announced by the route number alone or the route number and then the road name.
