Cottbus’ sea axis: new green connection between the city and the Baltic Sea!

On October 18, 2025, a new phase in the urban development of Cottbus was heralded. At the groundbreaking ceremony for the lake axis, Mayor Mohaupt gave the starting signal for the construction work, which will represent the lifeline between the city center and the future Baltic Sea. [Cottbus.de]. This 1.6 kilometer long route is being built on the route of the former Cottbus-Guben railway line, which has been closed since 2002.

The focus is on creating a climate-friendly experience space that not only benefits pedestrians, but also cyclists and local public transport. The implementation of this idea will take place in several construction phases. The mayor emphasized the importance of this project for the development of the Seevorstadt and the future harbor district on the Baltic Sea.

Construction phases and schedule

The construction work includes several stages, including rapid progress in the section from Franz-Mehring-Straße to the city ring, the implementation of which is planned for 2026. Another section is currently being prepared for planning, while the first official start of construction took place today for the section from Dissenchener Straße to Merzdorfer Bahnhofstraße. These measures begin with clearing bushes to make space for further work RBB24.

The total duration of the construction period is estimated to be around one year, so the aim is to put the sea axis into operation at the end of 2026 or at the latest by the 2027 cycling season. Around 4.13 million euros are estimated for the entire measure, which will be financed entirely from funding from the Federal Office for Logistics and Mobility.

A touch of art and community

To accompany the construction of the sea axis, new ideas for three themed islands along the route were collected in a competition. Around 600 Cottbus residents took part and submitted their suggestions to make the route more lively and attractive. The art installations to be implemented as part of the project come from the artists Katharina Hohmann from Berlin and Seraphina Lenz from Switzerland. This creative component will certainly make the Seeachse a special place and strengthen the sense of community in Cottbus.

The sea axis is not just a construction project; it is a step towards a sustainable and livable future for Cottbus. The planned connection between the city center and the Baltic Sea will significantly increase the attractiveness of the city and offer citizens a new, green space to relax and experience. This project shows that Cottbus is on the right track to meet the needs of its population while actively meeting the challenges of climate change.
