Old Rhine Bridge (Constance)
Encyclopedia
The Old Rhine Bridge at Constance spans in the Seerhein
. It is a combined road and railway bridge. In addition to one track of the Upper Rhine Railway
at kilometer 413.5, it carries the , the road that connects the borough of Petershausen
with the city center. The road bridge carries two lanes into the city center and three lanes in the other direction. Additionally, there is a bicycle lane in both directions on the left (as seen from the city center) and a sidewalk on the right. In the 19th Century, distance markers were placed along the Rhine; they start counting kilometers at this bridge.

. Since the medieval trade routes to northern Italy, France and Eastern Europe crossed in Constance, it is assumed that a wooden bridge existed below Constance before the 10th Century. The construction of a wooden pile bridge
in the flight of around 1200 CE is documented.
A mill was built into the bridge in 1418 or 1427 or 1437, because the bridge piles held back the water of the Upper lake
and increased the 30 cm difference in water level between the Upper and Lower lake.
A lack of stability led to the bridge over the Rhine being demolished and reconstructed around 1540. The new bridge was completed in 1544. It consisted of a covered wooden bridge, based on double pillars. connected at both sides to a stone arch bridge
and a draw bridge. A mill complex with a weir
completed the bridge structure. The wooden bridge superstructure, including the mills, were destroyed several times by fire and rebuilt, in at least 1548 and 1675. It was destroyed by fire for the last time in 1856. In 1857, the states surrounding Lake Constance decided not to rebuild the weir, because it was regarded as the cause of the extreme high water conditions around the Upper Lake. Until the new bridge was ready, a temporary wooden bridge allowed travellers to cross the Seerhein.
. Cunstruction Councillor Robert Gerwig
from Baden designed the bridge and led the construction team. The company Gebrüder Benckiser from Pforzheim
built the sub- and superstructures, starting in October 1858. The road bridge was opened to traffic on 3 December 1860.

, to fundamentally rebuild the bridge. The spans were unchanged, but the bridge was widened by about 50%. The company Ed. Züblin from Stuttgart was awarded the contract to build the substructure. Construction work began in November 1936. After a 190-meter-long temporary bridge was built downstream, the road bridge sections were taken apart, with the railway remaining in operation, albeit under restrictions. The superstructure of the old bridge, as well as the substructure, abutments and pillars were disassembled down to the water line. In the shelter of a sheet pile enclosed pit, timber piles with lengths of 18 to 20 meters were driven into the river bottom, the abutments were extended downstream and the pillars were widened. New abutments were then built, using concrete with exposed brickwork from granite from Waldulm. The pillars were encased in concrete in the shelter of the sheet pile enclosed pit. The contract for the steel superstructure was awarded to the company M.A.N. from Mainz-Gustavsburg. The bridge sections were constructed in the factory in Mainz-Gustavsburg and transported by rail to the site where they were hoisted in place using a gantry crane

In the longitudinal direction, the spans consist of continuous beams. Each bridge had two steel girders with variable height and a horizontal top flange design, which was located above the roadway. The bottom flange rests on the pillars and curves with a radius of about 100 meters.
In 1957 a third major carrier was inserted in the gap between the rail and road bridges. It bears the eastern road bridge deck.

In the Second World War, the Rhine Bridge remained intact. In the years 1956-57 the roadway was widened to meet the increased traffic in the city. For this, the corridor was used that had been reserved for the second railway track in 1938. This was possible because the BundesbahnBundesbahn

Bridge of 1860
The arch bridge was in total 17.85 m wide. It carried two railroad tracks and a 5.4 m wide road on the downstream side, plus sidewalks on both sides. The 127.8 m long structure had three spans of 42.6 m each. The superstructure consisted of four solid-walled, wrought-iron arched girders across each span.

Bridge of 1938
The total length of the new bridge is again 127.8 m, but this one is 26.95 m wide. The roadway was widened to 10.0 meters. This bridge has separate superstructures for the road, the railway and the non-motorized lanes. The piers and abutments for the railway bridge were designed to carry two single-track superstructures, of which only the eastern one has been implemented. View in the downstream direction, the first superstructure is the pedestrian walkway, the second is the railway bridge, then comes a four-lane road bridge, with a console carrying a bike path mounted on the western carrier.In the longitudinal direction, the spans consist of continuous beams. Each bridge had two steel girders with variable height and a horizontal top flange design, which was located above the roadway. The bottom flange rests on the pillars and curves with a radius of about 100 meters.
In 1957 a third major carrier was inserted in the gap between the rail and road bridges. It bears the eastern road bridge deck.
