The tramlines join Mainzer Landstraße at Platz der Republik, and the road then continues into Gallus, where it passes under Galluswarte S-Bahn station and past the Galluswarte watch tower, which marks the historic walls of Frankfurt. The section of the road in Gallus is known for its high concentration of car dealerships and garages. An alternative tram route to the south lets trams bypass part of Mainzer Landstraße around Galluswarte and a headshunt tram siding at Mönchhofstraße on the outskirts of Gallus let trams stop and reverse there at off-peak times.
