CHICAGO BUSES - 1973

The CTA was operating a bus network quite similar to the streetcar network inherited from CSL, and was operating much of the former Chicago Motor Coach system. That year would mark the CTA's first route cutbacks due to funding uncertainties. Chicago's last trolleybuses, primarily on the Northwest side, would also be eliminated that year. Those remaining trolleybus routes are shown in blue.

Green circles indicate CTA bus garages. In addition, North Ave. and Forest Glen housed the remaining trolleybuses, as indicated by the multicolored circles.

Route numbers are not shown here due to space limitations.

Separate panels show transit routes on Chicago's north and south sides.




Not shown are express bus routes, along with downtown shuttle routes, downtown routings, and routes serving suburbs which had replaced rapid transit routes.
