At the intersection of Ashland and Milwaukee Avenues, the Blue Line descends underground, swings over to Milwaukee Avenue, and continues southeast towards downtown under Milwaukee Avenue (with stops at {{cta|Division|Blue}}, {{cta|Chicago|Blue}} and {{cta|Grand|Blue}}). The line then turns east under Lake Street, crossing beneath the [[Chicago River]], and makes a stop at {{cta|Clark/Lake}}, where in-system transfers are provided to 'L' trains on the Loop.

East of Clark/Lake, the tracks swing south under Dearborn Street, with a continuous platform similar to the continuous platform used in the adjacent [[State Street subway]], with stops at {{cta|Washington|Blue}}, {{cta|Monroe|Blue}}, and {{cta|Jackson|Blue}}.

South of Jackson, the line turns west under [[Ida B. Wells Drive]] (with stops at {{cta|LaSalle}} and {{cta|Clinton|Blue}}, which is two blocks south of [[Chicago Union Station|Union Station]]). The tracks then emerge from a portal near {{cta|UIC-Halsted}} in the median of the [[Interstate 290 (Illinois)|Eisenhower Expressway]] (Interstate 290) and continue west.
