Just over a century ago the Minneapolis City Council directed the Milwaukee Railroad Company to construct a trench located just north of Lake Street, between Hennepin and Cedar Avenues, and 37 bridges for roads spanning the trench. This provided a grade separation between the railroad and the city’s automobile and streetcar traffic for three miles, from Hennepin to Cedar Avenues. Learn about the controversies surrounding this major civil works project in the early 1900s, the trench and corridor transitions from industry to residential use and from rail to bicycle traffic over the last 100 years, as well as what the future might hold for the Midtown Greenway. The program will be presented by local historians Tom Balcom and Aaron Isaacs.
