location
The Ellerntorsbrücke spans the Mr grave Fleet at the mouth of the Old Stone path in the Herrengraben and turned over several centuries, the direct connection between Hamburg and Altona represents.
history
Today's bridge, built in 1668, is the second oldest existing bridge in Hamburg and had several previous buildings on the same site, including a wooden bridge in the 13th century and a dam with masonry water passages in the 15th century, which was destroyed in the All Saints flood in 1570 .
In the late 18th century, the watercourse was cut off by a dam under the arches of the bridge and only in the middle arch was a flow open in the form of a lock opening, so that the bridge was mostly dry. In 1851 the Ellerntorsbrücke was widened for the sidewalks by means of wooden structures that cantilevered 1.50 meters at the side . These extensions were renewed in reinforced concrete in 1921 .
After being damaged during the Second World War , the eastern arch of the bridge had to be reinforced in 1946 with a 20 centimeter thick reinforced concrete shell. On June 22, 1960, the bridge was placed under a preservation order, on May 22, 1973 it was closed to vehicle traffic and became a pedestrian bridge.
In 1990, damage made a fundamental renovation of the structure necessary; the historical appearance of the bridge was restored. The side projections made of concrete were replaced by cornices made of reddish granite , the bridge paving was replaced with paving and the water and gas pipes removed. As part of the repair work, the dam under the bridge arches was also removed, so that the side openings are again flown through by water.
architecture
The three-arched bridge has a total length of 36.20 meters and a width of 12.75 meters, including the two later lateral extensions, each 1.50 meters wide. All three arches originally had a clear width of 8.60 meters each, but the concrete reinforcement added in 1946 reduced the width of the eastern arch to 8.20 meters.
The Ellerntorsbrücke rests on wooden piles driven into the ground. The vaults of the arches are made of natural stone, the superstructures are clinkered with bricks .
