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 traffic crossovers on the highway, began in September, 2011. This project eliminated the weaving movements of I-694 at its interchange with U.S. Highway 10 (US 10) and MN 51 in Arden Hills. This interchange often created one of the worst bottlenecks in the Twin Cities because drivers need to change at least one lane to continue either direction on I-694 between MN 51 (Snelling Avenue) and US 10. When the construction project was completed, the roadway of I-694 included three thru-lanes in each direction from I-35W at New Brighton to US 10 at Arden Hills; four thru-lanes in each direction
