Rollbahnbrücke, Road bridge in Kelsterbach, Germany
The Rollbahnbrücke is a road bridge in Kelsterbach that crosses over the A3 motorway and links two sections of the airport system. It enables traffic flow between the northern and southern areas of this important transportation corridor.
Construction of this bridge began in 2009 and was completed in 2010 to handle the airport's growing demands. The opening took place in 2011 and marked an important step in the region's infrastructure development.
The bridge represents German engineering excellence in transportation infrastructure, integrating road and air traffic requirements in a dense metropolitan area.
The bridge is part of a tunnel structure and offers four traffic lanes in each direction with separate emergency lanes. Vehicles travel under a continuous roof while aircraft land and take off above.
What makes this bridge unusual is its dual purpose: it serves as both a tunnel roof for road traffic and a taxiway for aircraft. This uncommon combination makes it one of Europe's most unusual infrastructure designs.
