Summary[edit]

Description
English: Original Captions: Western: "Three-way Intersection at Congress and Franklin Streets." and inscribed along bottom: "9148 4-27-02 Shaft No. 8 Congre ... [unreadable]"; Pages: "THREE_WAY INTERSECTION AT CONGRESS AND FRANKLIN STREETS." The captions are misleading; using the 1902 tunnel map as a reference, this must be a view west along Congress toward the intersection with Market St (now Wacker Dr.). For scale, the track in the photos is 14 inch gauge. The image is a composite of the two published sources to eliminate artifacts from printing and scanning.
