The Friends of the Bloomingdale Trail has this vision for the abandoned rail line that runs through several near northwest side neighborhoods:
The Bloomingdale Trail will be a linear park for walking, jogging, biking, strolling, and a greenspace for contemplation, observation, relaxation and recreation. It will be a commuter connector and refuge from daily urban life.
One major difference is that the Bloomingdale Trail, as currently envisioned, would be a bike commuter path while the High Line doesn’t allow bikes.
Perhaps my perception of Chicago bikers is skewed, but I can’t imagine relaxing in their presence and suspect that many would love to contemplate their quick and painful demise.
