B 103 renewal in Rostock: traffic safety for the next 15 years!
On November 7, 2025, a significant step was taken in Rostock's traffic planning. The section between the Rostock Reutershagen junction and the Kritzmow junction is now open to traffic. This measure represents the completion of the ceiling renewal over approximately 3.5 kilometers and is an important part of urban infrastructure expansion projects.
The renewal of the B 103 extends over a total section of 14 kilometers and was implemented in several construction phases. Careful attention was paid to keeping traffic disruptions as low as possible. Traffic can now move over the new roadway, while remaining work, including the dismantling of two central crossings, is due to be completed in the coming weeks.
Background and details
The improvement of the B 103 was divided into a total of five construction phases, which were carried out from November 2022 to November 2025. Here is an overview:
- Schutower Kreuz – AS Evershagen: November – Dezember 2022, 1 km, 1 Million Euro
- AS Lütten Klein – AS Evershagen: Mai – August 2023, 2,4 km, 3 Millionen Euro
- AS Reutershagen – AS Schutow: April – Juli 2024, 2 km, 3 Millionen Euro
- A 20 – AS Rostock West – AS Kritzmow: August – Dezember 2022, 5 km, 6 Millionen Euro
- AS Kritzmow – AS Reutershagen: August – November 2025, 3,5 km, 3,1 Millionen Euro
In total, around 16 million euros flowed into the renewal of the road infrastructure through these extensive measures. Over a hundred construction workers were involved in the work, which was successfully completed without any major disruptions, apart from occasional weather delays.
Cycle paths and sustainable materials
Another area that has been improved is the cycle path between the Schutower Kreuz and the cycle path bridge at the Westfriedhof, which was repaired in the summer of 2023 for around 141,000 euros. These steps are part of the city's efforts to increase traffic safety and quality for both drivers and cyclists.
The composition of the asphalt used plays an important role in the durability of the roads. Asphalt concrete, a composite material made from mineral aggregates and bitumen, is known for its durability and has been used for road construction since the 19th century. There are different mixtures such as warm mix and cold mix asphalt that can be used depending on the requirements. Recycling is also an important issue; Now, additives such as recycled asphalt products are used in new asphalt, promoting sustainable construction practices while reducing costs. Wikipedia reports that asphalt mixtures have been used in pavement construction since the 19th century.
The upcoming remaining work and future traffic regulation, with a speed limit of 80 km/h in the dismantling sections, will help to increase safety for all road users and maintain the new lanes in the long term. With an expected useful life of at least ten to fifteen years, Rostock citizens can hope for improved accessibility and fewer disruptions to everyday traffic.
