State Route 313 (New York–Vermont) VT 11 by 1938, which was then co-designated as VT 313 from New York to Arlington by 1940. VT 11 was truncated to Manchester between 1947 and 1952, leaving only the VT 313 designation on the New York – Arlington highway. In the late 1970s, US 7 was realigned onto a new limited-access highway through most of southwestern Vermont. The new highway bypassed Arlington to the east. In 1978, VT 313 was extended eastward by way of VT 7A and a new roadway to meet the new routing of US 7. State Route 313 (New York–Vermont) New York State Route
VT tank the VT 1-1 and VT 1-2. The test programme ended proving that a twin-gunned turretless tank could be created with enough technical effort, but had drawbacks in both practical and tactical use. The first VT tank, VT 1-1, was built in 1974 by Maschinenbau Kiel (MaK). One year later they produced the second VT tank, the VT 1-2. For further testing of the mobility and the concept of a tank with two main guns, five Gefechtsfeldversuchträger (GVT, "battlefield test-beds") were designed and built in 1975 and 1976. The VT 1-1 was based on the shortened chassis of the cancelled MBT-70
