The largest bridge of the so-called "Allertalbahn" from Gifhorn to Celle. In 1981, unfortunately, passenger traffic was stopped, after which the line was partially dismantled.
The railway bridge is to the west of Flettmar train station (Raiffeisen & Saatzucht Flettmar is still based there today).
The area around the bridge is also a designated nature reserve.
Unfortunately, there is a dead end at the bridge and there is no bike path here anyway.
