During this period, Munich’s public utility company Stadtwerke München (SWM) and the Munich Transport Corporation (MVG) will be renewing curved rail sections between Prielmayerstraße and northern Sonnenstraße, which will directly affect tram operations.
Trams 20 and N20 Now Also Affected – New Detour Routes in Place
In addition to previously affected lines 19, 21, 27, and 28, tram lines 20 and N20 will now also be impacted. These lines will no longer operate through the Stachus section as usual and will instead follow extended routes. Trams coming from Moosach will run from Hauptbahnhof Nord via Bahnhofsplatz and Karlsplatz (Stachus) to Sendlinger Tor, where they will turn around.
The stop at Karlsplatz (Stachus) heading toward Moosach will be relocated to platform 1 on Sonnenstraße. In the opposite direction, toward Sendlinger Tor, trams will use platform 2. At Sendlinger Tor, passengers will board at the second platform in the turning loop.
The night tram line N20 will depart from Moosach four minutes earlier than usual, now leaving at minute 04 instead of 08, according to MVG.
Tram Track and Underground Station Renovations Already Underway
Since June 2, SWM has been renewing the aging track infrastructure between Prielmayerstraße and Elisenstraße along the surface-level tram corridor at Stachus. At the same time, the pedestrian crossing from the Stachus fountain to Prielmayerstraße is being widened to improve safety for cyclists and pedestrians.
Ingo Wortmann, CEO of MVG, reported that despite the complexity of the work, the project remains on schedule. The first construction phase, which involved the renovation of diaphragm wall cover joints (Schlitzwanddeckelfugen), was completed two weeks ahead of schedule thanks to favorable weather.
The renewal of these structural joints, which are crucial to the stability of the road and tram lines above, began in November 2024. From January through mid-May, road surface repairs were carried out in the affected areas while tram operations continued. That changes with the current phase, which includes work on green spaces, roadways, and tracks.
Tram Service Suspended Between Stachus and Maxmonument – Replacement Buses Deployed
The tram route between Karlsplatz (Stachus) and Maxmonument will be fully closed until the end of August. Replacement buses and alternative routes will be provided. In September, the construction site will be dismantled and surface restoration will begin.
As tram service is suspended during this period, SWM is taking the opportunity to renew 600 meters of track between Prielmayerstraße and Elisenstraße on tram lines 19, 21, 27, and 28. In addition, six switches that have been in use for 19 years and have reached the end of their service life will be replaced. These efforts aim to prevent future closures and service interruptions.
Improved Infrastructure for Pedestrians and Cyclists – Wider Paths and Greater Safety
Another major focus is improving access for non-motorized traffic. The crossing from the Stachus fountain to Prielmayerstraße and the cycle path in front of the Palace of Justice will be widened. According to Mobility Officer Georg Dunkel, up to 3,000 pedestrians pass through this area during peak hours – making it one of Munich’s busiest crossings. The existing infrastructure can no longer accommodate this volume.
Sidewalks will be widened to nine meters, and the cycle path will be extended to 3.5 meters. A structural separation between pedestrian and bicycle traffic will be added, along with expanded waiting areas and a new guidance system for the visually impaired. Lowered curbs will improve accessibility for all.
Construction Officer Jeanne-Marie Ehbauer also announced that the traffic light system will be upgraded with tactile and acoustic signals for people with visual impairments.
Traffic Lanes Reduced Until Late November
Car traffic will also be affected. During the construction period, roadways will be reduced to two lanes in each direction. Work will largely take place under live traffic conditions to minimize disruption.
In late October, the roadway will be resurfaced during overnight hours, temporarily reducing the road to one lane per direction. Pedestrian routes will be redirected during this time. According to SWM, the entire construction project is expected to be completed by the end of November 2025, though delays are possible depending on weather conditions.
