The Neue Niederräder Bridge is a railway bridge in Frankfurt am Main .

traffic

The Neue Niederräder Bridge spans the Main at Main km 30,970 between the Gutleutviertel in northern Main and the Niederrad district in southern Main . It connects the main station with the former station and today's Niederrad stop and serves the traffic of the S-Bahn lines and between the main station, Frankfurt airport , Mainz main station and Wiesbaden main station . In addition, the Regional Express trains on RMV line 80 to Saarbrücken and Koblenz sometimes use the bridge.

Technical Equipment

The bridge consists of the Strombrücke , a steel tied arch bridge , with a clear width of 168 meters. This is followed by a 159 m foreland bridge in the direction of the main train station, a 75.5 m long crossing structure for freight tracks and a 59 m long crossing structure over the parking yard. In the direction of the airport, the river bridge is followed by a 75.5 m long foreland bridge. The bridge is a total of 545 m long.

The bridge carries a pair of tracks from the Frankfurt airport loop ( route kilometer 3).

The superstructure is 12.74 m wide, the hangers reach heights of up to 24.02 m above the top of the rails. The permissible speed is 100 km / h. A cant of 150 mm is built on the structure in the direction of the main station , the curve radius reaches its lowest value of 472 m north of the Main. The track center distance is 4.00 m.

The bridge was built just ten meters west of the Alte Niederräder bridge . The distinction by name between "old" and "new" Niederräder Bridge was only made through and after the construction of the New Niederräder Bridge.

history

In 1972 the Rhein-Main S-Bahn went into operation and a new train station was built at the airport . The airport railway, later the lines S14 and S15 of the S-Bahn, ran over the route of the Riedbahn and the double-track ("old") Niederräder bridge.

In order to relieve the line, a separate track structure was planned for the S-Bahn and the construction of a second bridge next to the (old) Niederräder bridge, intended only for the S-Bahn. Construction began in October 1976 and the shell was completed in May 1979. Scheduled operations began on September 30, 1979. This means that train traffic on the Riedbahn and the S-Bahn no longer obstructed each other.

At the same time, the Frankfurt-Niederrad station was relocated around 700 meters further south and a new stop was built, which improved the connection to the new Niederrad office district and improved the transfer to lines 12 and 15 of the Frankfurt tram .

As part of the project to convert the Frankfurt (Main) sports field junction, the construction of a third Niederräder bridge is planned. In April 2013, the Darmstadt regional council initiated the consultation procedure for the second construction phase. According to the planning status of 2014, construction of the new bridge should start from 2020, so that it can be used by long-distance trains in 2024. The groundbreaking ceremony is now expected in the summer of 2021 and construction will start in the late 2020s.

A double-track new line that can be driven at 100 km / h is to be crossed over the bridge to complement the existing line between the Stadion station and the main station. At the stadium, a level connection to the Mainz – Frankfurt am Main line is planned, and the Frankfurt am Main long-distance railway tunnel is to connect to the new Niederräder Bridge north of the Main in addition to the above-ground tracks in the southern area of the main station .
