TGP tunnels under Route 590
September 6, 2011 —
Just prior to Hurricane Irene’s arrival in the Upper Delaware region, Tennessee Gas Pipeline (TGP) crews tunneled underneath Route 590 in Lackawaxen Township during the ongoing expansion of its 300 Line Project. Shown here is a road bore machine, which runs on tracks, according to Jerry Creel, TGP’s 300 Line Project manager. A massive auger drills horizontally through earth and rock, depositing the pulverized material in the trench. Standing on the roadway, the vibrations could be felt through the road’s surface.
