Lindenthal, Nordrhein-Westfalen, Deutschland - The traffic situation on the A4 in North Rhine-Westphalia is currently significantly restricted by extensive construction sites. The aim of renewing and improving the structures of the highway in order to avoid future disorders and accidents.

In view of the damage to the DB crossing structure Eifeltor, a changed traffic routing is also necessary. According to Autobahn.de there are temporary detours on the coming weekends that also challenge the traffic flow in the region. The users of the highway are asked to adjust to bottlenecks and to keep an eye on the current traffic reports.

foresight and recommendations

The conversion of the traffic routing is considered necessary to protect the affected building that has been in operation since 1956. The construction site operation is expected to lead to increased congestion during the main travel times. It is advisable to plan alternative routes and, if necessary, consult the traffic news. In particular, heavy goods traffic, which weighs over 3.5 tons, is directed in both directions on diversion routes, which can also lead to disorders.

The comprehensive measures are part of the infrastructural renovation and should contribute to improving traffic safety and travel comfort in the long term, even if they cause inconvenience at short notice. Drivers are therefore well advised to adjust to the changed conditions in good time.
