I – Interstates in Dallas

a-to-z-letters-iI have never notice this in any other place I’ve lived, you tell me if it’s common, but each interstate in Dallas has more then one name. So, let me give you some directions. 

Ok, take 121 west to 114 south. 114 south will take you to Loop 12. Get on Loop 12 south to 30 east. 30 east will take you to 75 north. 75 north to 635 west. 635 west to Dallas North Tollway north and Dallas North Tollway north to 121.
Or, you can take Sam Rayburn Tollway south to John Carpenter Freeway south to Northwest Highway.  Get on Northwest Highway south to Tom Landry Highway east. Tom Landry Highway east will take you to Central Express North.  Central Expressway North to Lyndon B. Johnson Freeway West.  Lyndon B. Johnson Freeway to Dallas Parkway North and Dallas Parkway to Sam Rayburn Tollway.
Let’s try this again . . .
I prefer to take 121 north to Dallas North Tollway south to Spur 366 east to 75 north to 190 east to 121.
Or, Sam Rayburn Tollway north to Dallas Parkway south to Woodall Rodgers Highway east to North Central Expressway north to George Bush Turnpike to Sam Rayburn Tollway.
Or we can just stay home.
