Abstract :
THE FIRST SECTION of the long-planned Chicago subway was opened to the public October 17, 1943. The section of subway which now is in daily operation extends along State Street and is 4.9 miles in length. This is but the first step in a program which ultimately may comprise as much as 50 miles of subway in the city of Chicago.
