Divison is the most northern and last stop in the Milwaukee-Dearborn Subway. The station has a single island platform that is narrow with the usual white columns along the edges of both tracks. The ceiling at first glance looks like the normal deep-bore tunnel triple barrel vault ceiling but the roofs are clearly flatter and the mezzanine where fare control is directly above the platform with just a few more steps up to the street. The reason for this is the station was built using the cut-in-cover method. The rest of the Milwaukee-Dearborn Subway is deeper, just north of the station trains emerge onto an elevated structure for Damon. The station has a slightly longer mezzanine than most Blue Line stations with two staircases leading up to it at slightly different points. The southern one leads up to just a high exit turnstile, this is closest to the streetstair (with unique white sides) up to Polonia Triangle along Ashland Avenue between Milwaukee Avenue and Division Street. A small passageways of the mezzanine is outside fare control connecting this entrance to the one bank of turnstiles to a single staircase down to the platform below by a second streetstair up to the opposite west side of Ashland Avenue between Division and Milwaukee.
