So I just want to rant on tumblr.com about civic infrastructure, this will probably go on for a while
Of course when talking about civic infrastructure, you wind up in Chicago, and there is no better place to start with that than the proposed Circle Line which would have allowed people to make trips between L lines without going to downtown Chicago, the L is Chicago's public train system as we all know, it was studied in 2002 giving us this image showing how it would connect the city and transit lines
The Chicago Circle Line is very easy to build because the majority of the trackage uses existing infrastructure such as the current Pink Line or simply runs on Ashland Avenue. The main difficult section is building connections to the Red Line and Orange, which do not have easy-to-follow roads. In fact, the first phase has already been built because it used existing infrastructure The first phase which connected the Blue and Green Lines used the Paulina Connector, an abandoned line that was restored when the Pink Line was created. This means that the project is even easier because all that needs to be done on the west side is a bridge over the Chicago River to the Orange Line which would go through largely industrial, low density areas and some elevated tracks over Ashland Ave which would have been phase 2
