SUPERIOR, WI (KDAL) - After a two day weather related delay, the major reconstruction of Tower Avenue between Belknap and North 3rd Street began on Wednesday. The street has been blocked off and detours are in place. Merchants on that stretch of Tower will remain open throughout the project by using back entrances. The 13.3 million dollar reconstruction includes new sidewalks, street lighting and a new storm sewer system. The 6 month long project is expected to be complete late this fall.
