Complete closure of the L 608: Bubbles under asphalt cause excitement

The renovation work on the L 608 between Malsch and Neumalsch has now been completed and the road will be reopened to traffic today. Work on the section of road that runs above LIDL began on May 19, 2025 and was completed on June 13, 2025, as [rp.baden-wuerttemberg.de]. But why was it necessary to completely close the L 608 for almost a week?

An unforeseen problem became noticeable: bubbles in the asphalt surface layer above the BAB 5 bridge. The cause of this was trapped moisture between the asphalt surface and the protective layer underneath, which was converted into water vapor by high temperatures and thus led to pressure and bubble formation. This situation required immediate action, so the asphalt surface layer in the affected area was carefully removed and the defects were repaired. However, the exact causes of the moisture are still unclear.

Traffic management and diversion

Traffic was rerouted via the B 3, the L 67 and Daimlerstrasse. This ensured that disruption to motorists was kept to a minimum. Given the challenges faced during the renovation work, traffic management has proven to be extremely important to ensure smooth traffic flow.

With the reopening of the road, a speed limit of 50 km/h will be maintained in the area of ​​the bridge over the A5 until the causes of the bubble formation in the asphalt surface are clarified. This measure is intended to ensure the safety of all road users and avoid further problems, as reported by bnn.de.

Costs and maintenance measures

In total, the renovation costs amounted to around 850,000 euros, which were financed by the state. The original plan was to complete the work by the end of June, but the measures were completed two weeks earlier. This timely completion is particularly positive because just one week after the road was opened, the section had to be completely closed again for almost a week.

The importance of road maintenance cannot be underestimated. According to studysmarter.de, regular inspections are crucial to detect potential problems early. Proper maintenance not only ensures the longevity of road surfaces, but also prevents accidents and reduces the cost of major repairs.

The L608 has undergone a comprehensive renovation. Residents and commuters can now use the route safely and quickly again, although the affected areas should be kept in view so that such situations can be avoided in the future.
