A proposal for the highway and bridge was first made three decades ago for strategic reasons during the Cold War.
The project was reactivated to link the Frankfurt area, specifically the Hahn airport,  to the Belgian and Dutch harbors with updated plans drawn in the early 21st century.

The plan called for a 1702.4 m long steel box beam bridge that crosses the river at a maximum height of 158 m. The width of the bridge will be 29.0 m  to allow four-lane traffic.
Ten monolithic pylons made from concrete will support the bridge; their height varies between 15 and 150 m.  The estimated costs are 270 million euros.
Cost increases caused headlines.
The costs of the entire project amount to at least 483 million euros, with the bridge accounting for 175 million euros.
The project was completed in November 2019.
