Chicago’s 1941 State Street Construction February 20, 2019 Share Facebook Twitter Pinterest Multiple streetcars are in view on this busy scene in 1941 from during construction of the State Street Subway (used by CTA Red Line service, today). Like today, many surface transit lines share State Street. Since streetcars can’t just divert themselves around an obstruction, temporary tracks had to be built to reroute the car lines around excavation sites for the many entrances to the subway (and subsurface mezzanines). Based on signs visible in these pictures, services these streetcars were providing were predecessor services to routes that use State Street today, including the #29 State, #36 Broadway and #62 Archer.
