Willis Tower has a corner at Franklin and Jackson. South Shore's closest station is the VanBuren one, which is about a nine block walk. Those nine blocks take about 18 minutes to walk.
9 blocks
Sadly there are no lockers at Millenium station.
no. best way is millennium station to purple line and get off at Quincy. or better yet, take a cab.
I am assuming that by "owntown metra station" you mean "Ogilvie Transporation center". This is the main metra station. It's only about a block away. Inside Ogilvie, go to the Madison st main entrance. Exit and turn left on Madison st. Walk to the end of the block (Canal St) and Union station is right across Madison st. at the intersection of Madison & Canal. Good Luck!
