Closure for three weeks: Isar bridge in Oberhummel is being investigated!

From Monday, October 21st, the district road FS 13 between Oberhummel and Gaden will be completely closed for three weeks due to investigations on the Isar bridge. This measure is part of the planned renovation of the structure, which has been in operation for over 60 years. According to the district office of the Freising district, the bridge was built in 1963 and had a load capacity of around 30 tons, which is no longer up to date. Due to the increased volume of traffic, the bridge can no longer meet modern requirements.

The closure is expected to last until November 8, 2024. During this time, extensive investigations into the subsoil and the bridge structure will be carried out. “The route is completely closed to all traffic and a large area is being rerouted,” explained a spokesman for the district office. The closure will take place at the entrances to the parking lots on the Isar, which, however, are still accessible. The diversion for traffic from Langenbach will take place via state road 2350 to Moosburg and further along state road 2331 to Gaden, with appropriate signs being put up.

Necessary measures and future plans

For some time now, the roadway over the bridge has been narrowed using beacons to avoid overloading caused by two trucks crossing at the same time. But this solution is not sustainable and turned out to be inadequate. In order to permanently relieve traffic and ensure safety, the district committee decided in October 2020 to comprehensively renew the Isar Bridge and the adjacent Dorfen Bridge. These new buildings are intended not only to increase the load-bearing capacity, but also to integrate walking and cycle paths in order to improve traffic conditions for all user groups.

The current cost estimates now amount to around 15 million euros, instead of the originally estimated nine million. These higher costs are due to the fact that extensive materials and work analysis must be taken into account during planning. The final start of construction is still unclear as it depends on approvals and the status of the Dorfenbrücke.

At the recent meeting of the Environment and Planning Committee, Mayor Susanne Hoyer of Langenbach emphasized the importance of an additional temporary bridge that should be available to residents during the construction period. However, this bridge would only be intended for pedestrians and cyclists. However, financial and nature conservation aspects could speak against implementation, as Robert Stangl from the district office further explained. Each new step in the planning is carefully examined to ensure that all factors are adequately taken into account.
