en.Wedoany.com Reported - Norwegian tunneling company Metrostav Norge has completed 1 kilometer of excavation on the Røldal tunnel. Frode Lykkebø, project manager at the Norwegian Public Roads Administration, initiated the blasting for this milestone.

The project began with the first blast from the Seljestad side at the end of September last year. During construction, workers operated in winter temperatures as low as -25°C, while highly variable geological conditions posed ongoing challenges. The company stated that with 10.7 kilometers of tunnel still to be excavated, the remaining work is arduous and will bring new challenges and several key milestones.

The new Røldal tunnel in the Vestland region is part of the E134 highway upgrade, connecting Røldal and Seljestad, and will replace the original 4.6-kilometer tunnel built in 1964. The new tunnel is expected to open in 2031 and will become Norway's third-longest road tunnel.
