Main-Neckar bridge, Railway bridge in central Frankfurt, Germany

The Main-Neckar Bridge is a steel truss railway bridge over the Main at kilometre 32.770, linking Frankfurt's Gutleutviertel to Niederrad and Sachsenhausen. It carries four standard-gauge tracks: the western span the Frankfurt–Heidelberg line, the eastern the Frankfurt–Göttingen line. A footbridge with a ramp on the north side and a stairway with a bicycle rail on the south side runs along its east side.

Planned as part of the new Frankfurt Central Station, the bridge was built in 1883/84 on the site of the Gutleuthöfe, a medieval leper asylum, and first called Brücke an den Gutleuthöfen. It opened for freight on 1 August 1885 and for passengers on 18 August 1888. In 1927 it was rebuilt as a steel truss bridge; Wehrmacht engineers blew it up in March 1945, and it reopened in November 1946.

The bridge owes its name to the Main-Neckar railway whose trains use it; locals first called it Brücke an den Gutleuthöfen after the medieval leper asylum on the north bank. Its eastern footbridge, part of bicycle route 11 between Bockenheim and Niederrad, opened a southern ramp in March 2022.

You can view the bridge from the northern or southern Main riverbank, with good vantage points along the waterside paths. Daytime is when train activity is most noticeable if you want to see it in use.

The bridge crosses the Main at river kilometre 32.770, and its clearance is 7.50 m above the highest navigable water level. Because the structure provides only 5 m instead of the 5.30 m usually required by Deutsche Bahn, trains cross it at reduced speed.
