Work is coming along smoothly on Package IV-B that consist of the microtunneling installation which will cross the SR 874/ Don Shula Expressway & CSX railway as part of MD-WASD Area N Project. The microtunneling design included approximately 720 LF of 48-inch PCCP Water Main Carrier pipe within a 72-inch Steel Casing. The final installation depth was approximately 20 ft in order to be able to cross under an existing 66-inch reinforced concrete drainage pipe.
