for columbus:
light rail- i think that columbus needs light rail. i believe it will help improve life in general and encourage people to use public transportation. i enjoy my car and all, but taking I-670 in the mornings can be a real pain in the butt
city center- i hope something is done with city center. it would be nice if it could be turned into the mega star shopping center it was, with store like gucci, chanel, neimans, saks, macys or bloomingdales, vuitton, ralph lauren, etc... if not, i think a mixed use mall would be great, especially for all the people starting to move downtown. i think they should make it an outdoor mall like easton, except it would be in a real downtown(town square) environment. to me the new city center would have upscale/luxury stores, fountains, gardens, promenades, etc....(to make it really nice and attractive)!
I-70/I-71- this highway mess needs to be fixed. i think they should set up a toll system or add HOV lanes not only to this section of freeway, but to I-670 and 315. but i hope that something will be done in the next few years.
morse road/northland area- i hope that they continue with the great re-development in this area. i went to school in that area(go northland high vikings!!!) and i dont want to see it go to waste. i like what they are doing with the old northland mall site and the beautification of morse road!
parking lots- there are too many in downtown and i know they have potential to become residential space or office space or parks, etc...
that all that i could think off for now, but i am sure something else will come to mind and/or someone will mention something
