The Wiwilí Bridge ( Blue Bridge because of its paintwork , also called Stühlinger Bridge before the construction of the Stadtbahn Bridge) connects the Freiburg district of Stühlinger with the old town . It spans the tracks of the Freiburg main station and connects the church square of the Herz-Jesu-Kirche with the Konrad-Adenauer-Platz. The bridge is now a listed building and is used by up to 10,000 cyclists per day.
history
The overpass was built in place of an inadequate level crossing in the years 1885-86 by the Grand Ducal Baden State Railroad according to plans by Max Meckel , who shortly before had designed the Sacred Heart Church on the axis of the bridge. The construction was carried out by the Kaiserslautern ironworks . It was inaugurated as the "Kaiser Wilhelm Bridge"; However, this name could not prevail, in the population it was the "Stühlinger Bridge". It crosses the railway station tracks and access roads on five - because of the track systems - unequal tensions. The cost of the ironworks was 151,412 gold marks ; those of the whole building around 428,000 gold marks.
From 1909 to the end of 1961 line 5 ( Herdern - Haslach ) of the Freiburg tram ran over the bridge. With the Railway Crossing Act , the bridge became the property of the city of Freiburg in 1978, after the tracks had been removed as part of an initial renovation in 1972 and a new concrete track laid in order to ensure use for the next 15 years.
In the course of the redesign of the station area and the associated reconstruction of the abutment on the east side in 1996, the bridge was then closed to motor vehicle traffic and only opened to bicycle and pedestrian traffic. In addition to the abutment on the Stühlinger side, the bicycle and mobility station "mobile" with a bicycle parking garage was built in 1999, which has been called the Radstation since 2014 . In 2003 the bridge was named after Freiburg's twin town Wiwilí .
Fundamental renovation work began in March 2008, for which the bridge was raised in five successive sections by 1.50 meters in order to be able to work over the railway tracks. In addition to the replacement of many static steel parts and the road surface, drainage channels were installed at the edges of the road and in the edge area of the walkways to protect the bridge from corrosion. Shortly after the work began, a massive amount of asbestos was discovered that had to be removed. The pillars of the bridge were raised by approximately 50 cm to increase the safety profile for the railway. This increased the incline of the access and exit ramps of the bridge by half a percent. The work should originally have taken nine months and cost around 2.5 million euros. Due to the doubled steel consumption and the asbestos problem, however, the work lasted until September 2009 and cost 6.3 million euros. A spiral staircase that led from the northern walkway to the bus station was not restored after the renovation.
The Freiburg Marathon leads after renovation back over the bridge. On warm days, the bridge arches are sometimes used as seating. Tango is also danced on the bridge every now and then.
In winter, since the restoration, only split is spread on the bridge, because salt is forbidden to prevent rust damage to the steel.
Technical specifications
The entire length of the bridge from abutment to abutment was 161.8 m during construction, the roadway width 5.2 m, the footpaths on both sides measured 1.7 m each. The two-sided access roads to the bridge had to have a 4% gradient due to the adjoining streets. For the same reason, the side openings came to lie on even steeper slopes and the lower chords of the trusses had to be given an arched curvature due to the continuity of the road surface. The maximum height of the arches is between 2.79 m and 4.13 m. The total weight of the ironworks was 540.4 tons, but it has meanwhile increased to around 1720 tons (consisting of arches, supporting structure and concrete slabs).

Memorials
There are two memorials on the bridge: On the one hand, a cloak with a bronze Jewish star, apparently forgotten in a hurry, has been a reminder of the Wagner-Bürckel campaign , in which the Jews of Baden in the night of October 21-22, 1940 in the Gurs camp were abducted. The coat was created as a bronze sculpture by the artist Birgit Stauch, who lives in Baden-Baden. He was placed there by the deputy head of the Freiburg Cultural Office, Johannes Rühl .
On the other hand there are memorial plaques for the Freiburg communist and trade unionist Berndt Koberstein and the Freiburg doctor Albrecht "Tonio" Pflaum . You were murdered by the Nicaraguan Contras during a humanitarian aid operation in Wiwilí .
