State forestry felled dangerous trees in the Oker valley
Federal highway 498 between Waldhaus and Romkerhalle and Verlobungsinsel fully closed from August 5 to 7
(Clausthal-Zellerfeld) The Lower Saxony Forestry Office in Clausthal is removing trees in the Oker Valley for traffic safety reasons. For this purpose, a section of the federal road 498 will be fully closed from August 5 to 7, 2025. The engagement island located in the Oker stream bed with the Harzer Wandernadel stamping station will also be inaccessible. The section of the route from the Oker bus loop (Kästestraße junction near Waldhaus) to the Romkerhall waterfall is affected by the felling work. Following bark beetle infestation and climate damage, dead spruce trees must be removed from the danger zone of the road.
„During the road safety work, forestry machines can only operate from the road to remove the tall spruce trees between the main road and the Oker stream. The stream bed offers no possibility of reaching the dangerous trees,“ says district forester Daniel Göbel, explaining the safety measure. The district forester is relieved about the full closure of the main road ordered by the district of Goslar. „This allows us to defuse the threatening situation in the wild and romantic Oker valley with special technology. Forestry companies from the region are felling the dying spruce trees along the B 498 and pulling the tree trunks out of the rocky bank area.
For safety reasons, the popular engagement island with the stamping station may not be entered,“ points out Daniel Göbel. The E 6 hiking trail is still accessible.
Oker valley restricted area – without the state forests, the tourist highlight would be off-limits to visitors
For the fourth year in a row, the Lower Saxony State Forests are securing one of the main access routes into the Upper Harz and keeping the course of the river open for water sports enthusiasts and climbers from falling trees and potential floating debris.
„The Clausthal Forestry Office is investing in tourism infrastructure, hiking and canoeing as well as flood protection. If we leave the dead spruce trees in the stream bed, the Oker valley, which is popular with holidaymakers, water sports enthusiasts and climbers, would no longer be accessible,“ adds district forester Daniel Göbel.
Traffic will be diverted in Oker via Bad Harzburg and Altenau as well as via Goslar and Clausthal-Zellerfeld. The parking lot at the Waldhaus can be reached from Oker and access to the Romkerhall waterfall is free from the direction of the Oker dam.
