Construction of subway intersects with research campus in Martinsried
The extension of Munich's U-Bahn Line 6 to Martinsried, often referred to as the "Science Line," is making steady progress. This extension aims to support the scientific and biotechnological growth in the Martinsried area.
In mid-2025, significant investments and development efforts were made in Martinsried, including the expansion of scientific infrastructure such as the Life-Science-Campus by the Max-Planck-Gesellschaft, indicating ongoing support for improved transit connections like the U-Bahn extension [1].
However, the exact current construction status and a precise expected completion date for the U6 extension to Martinsried have not been explicitly provided in these documents. Given the strong political and financial support for Martinsried's scientific community and infrastructure, it is reasonable to infer that the project is a regional priority.
The new track of U6 leads approximately one kilometer beyond the current endpoint at Klinikum Großhadern to Martinsried. To navigate the unique challenges presented by the soil conditions in Martinsried, including contaminated areas, unstable layers, and inhomogeneous soil, innovative technology is being employed.
The soil conditions necessitate the use of a special pumping system to temporarily reroute groundwater at the construction site. The outer walls of the new tunnel are being concreted in 10-meter sections using the pilgrim step method. To ensure precision, the concrete for the complex geometries of the new station is poured with extreme care using special-purpose formwork bodies.
Innovative technology is also being used on the tunnel track itself. The tunnel walls are being concreted unilaterally against the bored pile walls, and the formwork units are being moved hydraulically without a crane. This approach streamlines the construction process and enhances efficiency.
A unique lid construction method is being used under "Am Klopferspitz" street to avoid traffic disruption during the construction of the new subway station. The new subway station features a cellular structure with eleven large openings in the ceiling, reminiscent of biological cell structures, to allow daylight into the underground space.
To prevent future subway traffic from transmitting disturbing vibrations to adjacent research facilities, a special damping system will be installed. This system includes a spring-mounted concrete slab, under-ballast mats, and maintenance-friendly openings. The goal is to lower the natural frequency of the ground to below 5 Hz for quiet working conditions.
The U6 is considered the central lifeline for Munich's science hub, connecting various research and educational institutions. With over 3,700 drill piles installed during the construction process, the foundation for the Science Line is taking shape. If everything goes according to plan, testing will begin in 2027, and the U6 will reach Martinsried, marking a new rhythm for science and urban development.
For the absolute latest progress and the confirmed opening date of the "Science Line" extension, checking the official Munich public transport authority (MVG) or Bavarian state transport updates would provide the most accurate information beyond these search results.

In light of the ongoing investment and development in Martinsried, such as the expansion of the Life-Science-Campus by the Max-Planck-Gesellschaft, it's anticipated that various industries, including science, finance, and technology, will thrive due to improved transportation connections like the U-Bahn Line 6 extension. As the new U6 track continues to be constructed, innovative technology is being employed to navigate challenging soil conditions, enhance efficiency, and potentially reduce vibrations that may affect adjacent research facilities. Simultaneously, the finance sector may be involved in providing the necessary funds for the project's completion.
