Jena. 15.09.2026. The planned construction of the Osttangente in Jena is sparking controversial discussions between urban traffic planners and environmentalists. The major project aims to consolidate traffic east of the city center and relieve sensitive areas such as the Löbdergraben and Karl-Liebknecht-Straße.
- Project: Expansion of the Osttangente via “Am Eisenbahndamm” and “Am Anger”
- Goal: Traffic calming of the city center and the Löbdergraben
- Planned start of construction: End of 2029 at the earliest, realistically 2030
- Estimated costs: 32 to 35 million euros (depending on subsidies)
The city’s plans for the new route include four lanes for long stretches as well as new bicycle and pedestrian paths. The reconstruction of the Angerkreuzung is particularly complex, as it is intended to be raised, among other things, to improve drainage during heavy rainfall. According to the Head of Urban Development, Dirk Lange, consolidating traffic on this north-south axis is the fundamental prerequisite for freeing adjacent residential and promenade zones from car traffic.
Criticism of Dimensions and Climate Goals
Opposition is coming from the BUND Jena, among others. Critics argue that the underlying plans date back to the early 2000s and do not sufficiently account for modern mobility shifts or changing commuter flows due to remote work and more flexible working hours. Furthermore, the four-lane expansion project is said to contradict the city’s climate goals, which aim for a long-term reduction in car traffic. According to calculations by environmental associations, some connecting routes, such as Karl-Liebknecht-Straße, could even face an increase in traffic instead of the hoped-for relief.
Renewed Needs Assessment and Timeline
In light of these objections, the city administration is showing a willingness to compromise. Department head Lange acknowledged that traffic volumes and the share of car traffic are continuously declining. Therefore, a renewed needs assessment is to be conducted before implementation to verify the actual necessity and dimensions. A step-by-step implementation in individual sections is also considered a possibility.
Some time will pass before the first construction measures begin. A start date is envisioned for no earlier than the end of 2029 or the year 2030, with a construction period of approximately four to five years. Financing is heavily dependent on the approval of subsidies. Meanwhile, the four-week period for filing complaints with the Thüringer Landesverwaltungsamt is currently underway.

Background: Traffic Development in the Saale Valley
Traffic flows in Jena are heavily channeled by the narrow topography of the Saale valley. Bridges like the Camsdorfer Brücke and central axes like the Löbdergraben have been among the most heavily burdened bottlenecks for years. Major road construction projects must therefore always balance capacity for supra-regional commuter traffic with urban planning goals for noise and emission reduction.
