BACKGROUND:
The North Aurora Road Underpass and the Wisconsin Central/CN Railroad Improvement project (CIP# BR005) is a joint effort between the cities of Naperville and Aurora as well as the Naperville Township.

Various options of avoiding the conflict have been reviewed and proposed to Enbridge, with none gaining approval. Relocation of the Enbridge gas pipeline is required.
DISCUSSION:
During the preliminary design stages of the project, a 34-inch diameter Enbridge petroleum gas pipeline was identified and accounted for in the proposed roadway profile. At that time, it was determined that a roadway profile could be constructed such that proper clearance between the proposed roadway and the existing gas pipeline could be achieved. Recent potholing ...
