South of Tenleytown, the rock tunnel curves east to head under Yuma Street NW. At the intersection of Yuma and Connecticut Ave, the Red Line turns due southeast again to follow Connecticut Ave, still in Rock Tunnel. The first station along Connecticut Ave is Van Ness-UDC. Van Ness is another classic deep bore stop with the classic island platform and four coffer vault. This station is not that deep by rock tunnel standards, being around 80-90 feet deep. The UDC name comes from the University of the District of Columbia, which is just to the west. This station opened in December of 1981, as part of the extension from Dupont Circle to Van Ness. It was the Northwestern Terminal for about 2 and a half years, until the Grosvenor Extension opened.
