Composite Twin Cities Future Urban Transit Network

Putting together the maps from four previous posts:
* Saint Paul Radial Lines
* Saint Paul Circle Line
* Minneapolis Orbital Line
* Minneapolis Circle Line
we have a composite Twin Cities urban transit network (excluding shared right-of-way buses and the largely non-urban commuter rail). Some stray lines have been cleaned up from previous maps, and alignments slightly more precisely drawn for the existing.
The color coding is as follows:
* Brown – Previously Planned or Already Built Light Rail Lines
* Purple – Proposed Minneapolis Streetcar Network
* Orange – Inner Circle
* Red – Outer Circle
* Green – Posited route alignment alternative
* Blue – Saint Paul Radial Lines
