Description
The project was part of the extension of Glenmont Route north into Maryland and included Wheaton Station and two approx. 2500 m long running tunnels as well as ventilation shafts and a cross-adit. Ilbau America, advised by Dr. Sauer & Partners, recommended changes to the existing conventional design and introduced the New Austrian Tunnelling Method (NATM), which was then used to construct the station tunnels, running tunnels and ancillary structures. The shaft at Hildarose Drive was constructed in conjunction with a large double cross-over.
