News Article: Renovation of State Road 309 (Süsel – Lehmkamp) in Schleswig-Holstein
Construction's final phase commences
The Schleswig-Holstein State Road Construction and Traffic Authority (LBV.SH) has announced a comprehensive renovation of State Road 309 between Süsel and Lehmkamp, including the accompanying bike path. The renovation, which began on May 19, is expected to continue until approximately mid-July.
Scope of the Renovation
The project includes the renovation and resurfacing of Landesstraße 309, road repairs, drainage system upgrades, and signage improvements. A significant part of the renovation involves the bridge over the B 76, which is undergoing extensive works as part of the ongoing project.
Timeline and Phases
The renovation is divided into three phases, with the first phase commencing in mid-September (tentative) and expected completion by the end of November 2025. The working hours are from 7:00 AM to 6:00 PM, Monday to Friday, with no work on weekends or public holidays.
- Phase 1: Preparatory works including traffic signal setup and initial surface repairs (Weeks 1–2)
- Phase 2: Main resurfacing and drainage upgrades (Weeks 3–6)
- Phase 3: Final paving, signage, and road marking (Weeks 7–8)
Traffic Management and Detour Routes
During the renovation, partial closures and full closures will be implemented in some sections. The road will be reduced to one lane, controlled by traffic signals allowing alternating traffic in partial closures. Full closures, planned for 1-2 weekends during the final paving phase, will require detours.
For motorized traffic heading from Lehmkamp to Süsel, the suggested detour route is via B 432, B 432 towards Ahrensbök, K 55, B 76 Eutin, and back to Süsel. Alternative local roads may also be signposted.
Cyclists are advised to use the detour via Neustädter Straße and Lehmkamper Weg until July 2025 due to the ongoing renovation of the accompanying bike path.
Traffic Advisories
Drivers should expect reduced speed limits (30-50 km/h) in construction zones, increased travel time (estimated +15 to 30 minutes depending on traffic), and heavy vehicles being encouraged to use alternative routes to minimize congestion. Cyclists and pedestrians may encounter temporary closures or rerouting of sidewalks and bike paths. Emergency vehicles will always have priority access.
General Recommendations
To ensure a smooth journey during the renovation, drivers are advised to plan trips in advance, stay updated through local news outlets and Schleswig-Holstein transport authority announcements, and follow all posted signs and traffic control devices for safety.
The traffic management for the road construction has been coordinated with the police, traffic authority, district, municipality, local communities, and the bus operator. However, the works are weather-dependent, so schedule changes are possible. The detour for motorized traffic does not affect the accessibility of adjacent properties for residents, except during paving and asphalt works when access may not be possible.
For more specific details, such as official documents or updates, you may want to check the Schleswig-Holstein Ministry of Transportation or local municipal websites closer to the renovation dates.
The renovation project on State Road 309 in Schleswig-Holstein extends beyond its transportation infrastructure, as italso includes upgrades to the drainage system and signage improvements, which fall under the sectors of public-transit and infrastructure finance. In collaboration with the bus operator, the traffic management for the road construction has been coordinated to ensure smooth public-transit services during the renovation.
During the renovation, the suggested detour route for motorized traffic headed from Lehmkamp to Süsel involves the use of major roads, such as B 432 and B 76, which are part of the national transportation network. As a result, the detour may also be relevant to travelers using various modes of transportation, including finance and transportation sectors.
