Jena, 31.07.2026: The City of Jena has published the construction site report for the 32nd calendar week (August 3 to August 9, 2026). In the coming days, new full road closures will be added to the city area, while several lengthy major projects on important commuter routes continue simultaneously.
- Period: 32nd calendar week (03.08. – 09.08.2026)
- New full closures: Eugen-Diederichs-Straße, Mühlenstraße, Otto-Schott-Straße
- Major projects: B 7 (Mühltal), Naumburger Straße, Forstwegbrücke
- Important detours: Mühltal (B 7), Naumburger Straße via L 1070 (Bürgel)
New closures and restrictions starting August 3
Three new construction sites will lead to restrictions in the Jena road network during the 32nd calendar week:
- Eugen-Diederichs-Straße: A full closure will be in effect from August 3 to August 14, 2026, due to fiber optic work. The first construction phase affects the area from Löbichauer Straße to Julius-Schaxel-Straße. In the second phase, work will shift from Julius-Schaxel-Straße to the level of Berthold-Delbrück-Straße. A detour is signposted via Löbichauer Straße, Karl-Liebknecht-Straße, and Am Steinborn.
- Mühlenstraße: Due to building renovations at house number 135, a full closure will apply from August 3 to August 28, 2026. Vehicle traffic will be routed via Lichtenhainer Oberweg using a traffic light system. Pedestrians and cyclists can pass the construction site.
- Otto-Schott-Straße: Due to the expansion of the district heating network, the street will be fully closed from Kronfeldstraße in the direction of Schleidenstraße from August 3 until presumably November 20, 2026. Individual traffic will be diverted via Magdelstieg.

Background & Commuter Tips: Traffic Flow in the City Area
Due to the simultaneous strain on several main traffic axes – including the B 7 in Mühltal and the arterial roads heading north and south – the city administration recommends that all road users allow for significantly more travel time. If possible, commuters should switch to public transport or use long-distance detours. Further reports on the traffic situation can be found in the Traffic & Mobility section.
