Why not get rid of Lake Shore Drive's At-Grade Intersections

So why not remove all of them? The resulting reduction in transit dependence could allow for the removal of some el train lines which blight enormous parts of the city  :bigass:

Is it a money issue?

From Monroe to McFetridge there are a couple of issues.

There is a long standing covenant for Grant Park which requires it to maintain an unobstructed view of Lake Michigan.

This means to remove the lights in this area, LSD would have to go down.

While technically possible, it would require a Boston like "big dig" to get LSD below lake level.

Grant Park is all landfill that was recovered from Lake Michigan and certain parts are still subject to subsidence. Closer to Michigan Avenue the city was able to create Millennium Park by covering the former Illinois Central tracks (which were originally on piers in the actual water).

So you either raise the entire park or lower the entire road to stay in compliance with the covenant.

Chicago has had long conversations and engineering reports on the possibility of connecting Queens Landing and Buckingham Fountain using some sort of pedestrian viaduct under LSD.

One of the big issues with this has been drainage. An elaborate pump system would have to be installed as it is illegal for that water to be vented directly into the lake. It has to pass through the city system.

Which L trains, specifically, could be removed if the intersections were grade-separated?  Lake Shore Drive doesn't even come within a half-mile of any elevated CTA station.

(OK, as the crow flies, I suppose it gets to a half-mile from the Loop itself...)

The Green Line runs on a roughly parallel alignment. If LSD had all this extra capacity, many Southside residents could drive to work. For those that can't afford cars or don't have parking available at work, you can put a dedicated bus lane on the LSD.

If you’re trying to drive into downtown Chicago when you have a train line available you’re doing it wrong.  Upgrading LSD does little to impact the overall bottleneck downtown is and the overall lack of limited access capacity getting there. 

There was this guy on the forum once that was into Sabbs that thought he had all the answers for that...  :rolleyes:

I don't think it's feasible for LSD to be converted into a full freeway at this point without dumping huge sums of money to accomplish that. Huge sums of money that the city nor the state have right now.
