The Trappentreustraße begins at the southern end of the Donnersbergerbrücke at the intersection Landsberger Straße (B 2 direction Augsburg) and runs south.

The secondary lanes serve as feeders to the Landsberger Straße and the side streets.

[3] Trappentreustraße in the area of the Mittlerer Ring plays a significant role in the Munich transport network.

In addition to several bus lines, north of the Donnersbergerbrücke is the location of the station, which carries the same name, and immediately south of Heimeranplatz are the S- and U-Bahn station, also named Heimerplatz, on the Münchner Südring.

For the dormant traffic a parking space management was introduced in the Trappentreustraße (southern section).

In this context, the Trappentreustraße was built and was initially an 18 meter wide side street.

[5] In the following years, the district intersected this partly eight-lane main traffic axis.

In order to prevent the passage of the entire Trappentreustraße for private traffic (which should use the tunnel), a so-called "plug" was installed at Gollierplatz.
