Workers continue to make progress underneath Bascom Hill, where they’re using a custom-made borer to excavate a 640-foot-long tunnel to carry utilities. The crew currently has excavated 300 feet from South Hall toward the northeast corner of Bascom Hill, where it expects to break through by the end of the week. An intermediate jacking station is temporarily dividing the length of tunnel because earth pressure is making it difficult to hydraulically push the length of metal tunnel in any further as one piece.
