Talk:LaSalle Street Tunnel

Untitled
I work in the Reid Murdoch Center at 325 N. LaSalle. The old road access to the north end of the tunnel is in front of the building, but the tunnel is now sealed off. The Reid Murdoch Center's sub-basement lies over a portion of the tunnel, and a construction superintendent for the landlord described an inadvertent breach into the tunnel. During a flood in the sub-basement workers jackhammered a hole through the basement slab to drain the water, presumably into the river. Instead they found the tunnel which was filled with gravel and, acting as a sump, drained the basement very quickly.

The ramp which provided access to the tunnel is still used to get to Carroll Street and grade-level entrances to several buildings in the area. (This part of the city is built up about 25' above grade) There is an abandoned rail spur running along Carroll which goes west under the Merchandise Mart to the old rail bridge at the river, and east beyond Clark Street to regions I have not explored. —Preceding unsigned comment added by 173.200.133.130 (talk) 18:59, 30 July 2010 (UTC)
