The lift bridge Hunte bridge was a drawbridge that during the B 212 between Berne and Elsfleth the federal waterway Hunte few kilometers from its mouth into the Weser crossed. The bridge was a listed building .
history
The bridge was built from 1951 to 1953 on behalf of the Oldenburg-Ost road construction authority and replaced a makeshift bridge for the swing bridge built there in 1908 and blown up during World War II . In 1998 the bridge was added to the list of architectural monuments .
Technology and dimensions
The lifting part of the bridge, built from riveted steel truss , had a span of 53.28 meters (from support to support) and a clear width of 52.0 meters (between the abutments). The width of the bridge was 13 meters (between the railings), that of the carriageway was seven meters, and the cycle / footpaths were two meters on each side. The weight of the lifting part was around 310 tons .
On both sides of the bridge there was a lifting tower made of riveted steel framework with a total height of 30 meters. The counterweights each weighed around 155 tons.
The lifting part of the bridge could be raised in two stages by an electric motor with 42 kW power . In the first lifting stage the lifting part could be raised four meters, in the second lifting stage 20.3 meters. The lifting of the lifting part took about 0.5 minutes in the first lifting stage and around four minutes in the second lifting stage. The electric motor was located in the middle of the bridge, the power transmission took place via longitudinal and transverse waves with gears.
With the lifting section below, the clearance height at mean high tide (NN +2.09 meters) was 4.23 meters. This resulted in a clearance height of 8.23 meters in the first lifting stage and a clearance height of 24.53 meters in the second lifting stage (each based on mTHW).
business
The lift bridge was opened by a bridge keeper for whom a bridge keeper's house with a control room had been built on the left bank of the Hunte. The bridge keeper's house was manned from two hours before sunrise to two hours after sunset every day. During this time the bridge could be opened for shipping.
Before the bridge was opened, which was done from a control stand on the bridge superstructure, the barriers on both sides in front of the bridge were closed and the bridge was closed to road traffic.
Construction of the B 212
In the course of the re-routing of federal highway 212, a new bridge over the Hunte was built between 2010 and 2015 to the east of the lift bridge. It is a bascule bridge and has been in operation since December 10, 2015. The old lift bridge was dismantled at the end of August 2018. A possible subsequent use could not be realized. At the beginning of 2011, the then Mayor of Elsfleth, Diedrich Möhring, suggested rebuilding the bridge on the Elsfleth campus of the Jade University . There it could have led over the Lienekanal and connected a planned expansion of the campus to it.
