The replacement for the dilapidated bridge from Schöngeisinger Straße to the Lände will be built from reinforced concrete.
The Committee for the Environment, Transport and Civil Engineering decided on this cheapest option.
The provisional facility through which traffic should flow during the construction period was particularly controversial.
Fürstenfeldbruck
- The temporary bridge, which will run a few meters next to and parallel to the current structure, costs less than 734,000 euros.
Christian Götz (BBV) thinks there is a lot of money for tearing down the temporary structure again after the new building has been completed.
“But I also have a stomachache with it for ecological reasons,” he said.
At least this could be taken from him by the planner Sven Zwerner from the engineering office of the same name.
There are companies that have specialized in such temporary solutions.
“The bridges will be reused,” said the planner.
Even the concrete of the abutments can be recycled, so that the temporary structure is ecologically unproblematic.
Nevertheless, Götz suggested simply keeping the bridge.
“We could then handle pedestrian and cyclist traffic there.” In addition, the new construction of the so-called Schlachthofbrücke could then be made a little narrower and only handle car traffic there.
Alexa Zierl (ÖDP) didn't like that because it contradicts the plan to create so-called “shared space” on the new bridge - an area in which all road users have equal rights.
According to Zwerner, Götz's suggestion is technically possible.
However, you have to pay attention to the inn on the land.
The temporary solution ends close to the entrance area and leads to a cramped situation there - a fact that Markus Droth (FW) had previously pointed out when it came to the width of the temporary solution: should it be one or two lanes?
Droth would favor the single-track solution so as not to narrow the inn any further.
"However, a traffic light would then be necessary," said the FW city council member.
So he wanted to know whether there was enough space on Schöngeisinger Strasse when turning had to wait.
Zwerner did not have an answer to this, as the normal traffic counts are not sufficient for an assessment: "You have to look at the peak times to be able to say something about any backlogs," he explained.
Whether the bridge can be built with one or two lanes also depends on the heavy goods traffic of the municipal utilities, which the power plant on the site has to approach.
In principle, the committee members preferred the single-track variant, but also accepted the broader solution if discussions with the municipal utilities revealed this necessity.
A suggestion by Mirko Pötzsch (SPD), who found a provisional solution in a completely different place as a “charming solution”, did not come into play: a bridge to the west of the football field on the Lände. Pötzsch would have liked to have this later as a pedestrian and cyclist bridge. According to Zwerner, it's like “shooting at sparrows with cannons”. Because the bridge would also have to be designed for heavy goods traffic, only to later only have to carry pedestrians and cyclists.
In addition, the planner doubts that the water management authority will give its permission for the solution, since another bottleneck would be created and thus exacerbate the already existing risk of flooding. And last but not least, you are moving in a biotope area, which in the event of an intervention sets in motion a lengthy process, since compensation areas have to be created. However, time is of the essence as, according to an expert report, the bridge will only last until the end of this year. Mayor Erich Raff (CSU) also rejected the solution because the football games planned for the summer would be followed by truck traffic in the immediate vicinity.
It was undisputed that the new bridge will be made of reinforced concrete.
For design reasons, Götz would have “preferred to see a steel structure than a run-of-the-mill concrete structure”.
However, the costs are a weighty argument.
And that amounts to more than 3.6 million euros for the steel solution compared to 2.8 million euros for the reinforced concrete structure.
The committee therefore voted unanimously in favor of the cheaper variant, which is almost nine and a half meters wide and designed for “shared space”.
