Fürstengraben gets new road surface

The Fürstengraben will be renovated in a section around 315 meters long from 09.03. to 10.04.2026. The work will begin west of the streetcar track area at the Löbdergraben / Saalbahnhofstraße / Lutherplatz junction and end around 65 meters after the Bibliotheksplatz / Weigelstraße junction. The junctions with Bibliotheksplatz, Weigelstraße and Schlossgasse will also be included. In total, the project covers an area of around 3,900 square meters.

Why is it being built?

The measure is necessary because the asphalt surface is getting on in years and there is increasing damage. The top four centimetres of the asphalt layer must therefore be renewed. In areas with deeper damage, the underlying layers will also be replaced.

In addition, west of the Weigelstraße junction on the south side, the kerb guidance will be adjusted and renewed for around 50 meters.

The construction work is being carried out by STREICHER Tief- und Ingenieurbau from Jena.

How traffic will flow during the construction period

The Fürstengraben remains passable despite the construction work. In order to keep restrictions to a minimum, the road will not be fully closed.

The following applies during the construction period:

• Traffic heading out of the city (towards Straße des 17. Juni / Weimar) will be one-way and remain possible.
• Traffic heading into the city from Weimar will be diverted via Erfurter Straße - Katharinenstraße - Lutherstraße - Ernst-Haeckel-Platz - Knebelstraße.

The work will be carried out in two construction phases with half-sided road closures.

Accessibility of the neighboring streets

During the construction period, the junctions with Weigelstraße, Schlossgasse, Bibliotheksplatz and Zwätzengasse cannot be reached directly from Fürstengraben.

• Weigelstraße and Schlossgasse can be reached via Leutragraben, Teichgraben, Nollenplan, Kollegiengasse, Eichplatz, Rathausgasse, Jenergasse and Hinter der Kirche. To this end, the one-way system in the street Hinter der Kirche will be temporarily suspended.
• Bibliotheksplatz, Zwätzengasse and Ballhausgasse can be reached via Saalbahnhofstraße, Käthe-Kollwitz-Straße and Nollendorfer Straße.
• The Hotel Schwarzer Bär can still be reached via Zwätzengasse and Ballhausgasse. The one-way traffic regulations will also be temporarily adjusted here.

Information for pedestrians and cyclists

For safety reasons, the construction site cannot be crossed directly on foot or by bicycle during the works. Crossings are possible at both ends of the construction section:

• To the east via the traffic lights at the Löbdergraben / Saalbahnhofstraße / Lutherplatz junction.
• To the west via a temporary traffic light that switches green on request.

Crossing in the Schlossgasse / Zwätzengasse area is not possible. Detour will be signposted.

Kommunalservice Jena asks all road users and residents for their understanding for the necessary restrictions. The aim is to restore the Fürstengraben to a good and safe condition.
