Weißer Stein (Eifel) 2007 the University of Liège executed measurements and found a height of 692 m (TAW, Belgian standard). The altitude meter of Google Earth caused some doubt about Signal de Botrange (694 m TAW) as Belgium's highest point because its vertical reference EGM96 deviates a couple of meters from the German Normalnull and the Belgian TAW, thereby suggesting an altitude of 701 m for the Weißer Stein. An accurate control by the Belgian National Geographic Institute in 2010 showed the Weißer Stein to be at maximum 693.3 m TAW (=691 m NN), with which it differs by less than 1 m
Interstate 694 There was a two-lane bridge across the Mississippi river where the current I-694 bridge is today. That bridge was constructed as part of a defense initiative authorized in 1942 at the beginning of World War II. The construction of I-694 to Interstate standards was authorized in 1956. The first section of I-694 completed was between US 10 at Arden Hills to I-35E at Little Canada in the early 1960s. The last section of I-694 completed was between I-35E at Little Canada to its junction with I-94 and I-494 at Oakdale–Woodbury, completed by the early 1970s. I-694 was built as the
