text: Yeah... I55 is not called Memorial Drive by any local, and it's not on any official signs that I know of.
  
  Looks like the name dates back to the TIGER imports, and I *believe* that I55 roughly follows the path of where Memorial Drive used to be before the interstate highway system, so that could have been where TIGER got the name from.
  
  In any case, I've removed the name from the entire stretch of I55 between downtown & I270.

  Resolving.
