The Riga Northern Transport Corridor is the largest transport infrastructure project in Riga in recent decades. At the end of 2011, JSC "Ceļuprojekts" completed a sketch design of Stages 3 and 4.
The structure of the overpass is an arc. The span of the reinforced concrete arch is 56 m and the span is 7.325 m (f/l = 1/7.645), which is considered to be a relatively slender structure for this type of structure.
The idea of building a road to cross the ravine was conceived in the 1950s and 1960s, when a small-radius (70-250 m) road with a very steep rise and fall (5-6%) profile was traced around a mill near Lorupe.
