Complete closure of the B494 and B65: traffic turnaround in Peine from July!
Extensive road construction work is imminent in the northern German region. From July 3, 2025, federal highways 494 and 65 are expected to be completely closed. The construction work, which affects the section from Rosenthal to behind the junction to Handorf (K 31), is expected to last until the end of July 2025, although delays due to weather are possible. This reported regionalheute.de.
The measures involve a financial outlay of around 530,000 euros, which is borne entirely by the Federal Republic of Germany. The Lower Saxony State Authority for Road Construction and Transport (NLStBV) asks road users to understand the resulting traffic disruptions.
Detour route and traffic disruptions
The traffic diversion will take place via the B 65 / L 413 roundabout towards the south. The route leads via Groß Solschen, then along district road 72 to Groß Ilsede, before joining the B 444 and the B 65 to Peine. Traffic coming from the northwest is routed from the B 444 via the L 412 to Peine-Vöhrum and vice versa. Residents and commuters should prepare for longer journey times.
This construction project is just one of many that are currently being carried out in Lower Saxony. The NLStBV is responsible for the planning and implementation of large infrastructure projects. The authority looks after over 4,600 km of federal roads and several thousand kilometers of state and district roads in the state. As part of the current projects, various bypasses and the improvement of existing traffic routes are also planned, as further information shows Niedersachsen.de emerges.
The program staple of road construction in Lower Saxony
The NLStBV looks back on a rich history that dates back to 1762, when King George III. founded the Royal Electoral Road Construction Intendance. Since then, a lot has happened in road construction in Lower Saxony. The authority is not only responsible for maintaining roads and bridges, but also for planning new transport projects that help improve road traffic. At a time when mobility is a key issue, these measures are more important than ever. A detailed overview of their tasks and the available infrastructure projects can be found on wikipedia.de be read.
Over time, hundreds of projects have been implemented that improve safety and traffic flow on Lower Saxony's roads. The announcement of the closure of federal highways 494 and 65 is a further step in this commitment, with the authorities always trying to make the construction work as smooth as possible and to keep the impact on residents and road users as low as possible.
