Wilhelmshöher Allee in Kassel: Night closure announced for construction work!
Wilhelmshöher Allee in Kassel will be closed for one night this Thursday, June 26th. The closure begins at 8pm and ends at 6am on Friday June 27th. The upper section that leads out of town from the intersection of Bremelbach-/Landgraf-Karl-Straße is affected. The reason for the temporary traffic disruptions is work on laying a water pipe, which will also shape the streetscape in the coming weeks.
After the nighttime closure, only one lane will be available for approximately three weeks. To ensure that there are no unnecessary traffic jams during the time of restrictions, a diversion will be set up via Landgraf-Karlstrasse and Baunsbergstrasse. However, market participants do not have to worry about the pedestrian and cyclist crossing over Wilhelmshöher Allee, as it will remain open during construction work.
Replan in good time
However, residents of Kassel's Gräfestrasse already have voices pointing out the increased volume of bicycle traffic. Some people here complain about cyclists rushing in a hurry and not following traffic rules. It is therefore advisable to be particularly careful during this time and, if necessary, re-plan times and routes.
Traffic experts who are involved in planning such measures agree that safety for all road users must always be the top priority. With its Vision Zero, the Safe Roads Initiative aims to prevent traffic accidents that cause serious personal injury and includes the expertise of experts and modern digital tools in its analysis. Information and tools like this MUSIC platform help to precisely evaluate safety-relevant data and include it in planning.
Important information for drivers
There are currently no reports of further dangers or obstructions on Wilhelmshöher Allee. However, drivers should pay attention to the construction site and, if in doubt, take alternative routes to avoid unnecessary delays. Traffic jams, poor visibility or obstacles are not expected at the moment, but as can often be the case in traffic situations, traffic is quickly blocked at the slightest provocation.
The city of Kassel expressly asks for your understanding for the inevitable noise during construction work. In the long term, the new water pipes should offer an improvement in water supply and infrastructural safety for almost all residents. In the hope of quick and uncomplicated construction work, everyone involved hopes that Wilhelmshöher Allee will be fully accessible again after July 18th.
