need to repeatedly build support columns, slowing progress. By the start of 1956, 350 meters (1,150 ft) had been blasted. The breakthrough took place on 8 March 1956. The original blasting had only created a narrow profile and the rest of the work went to widening it. A 180-meter (590 ft) cutting was made on the south side of the tunnel, to make a place for the station. The concrete walls were finished in
November 1957. A road bridge was built over the northern entrance to allow Mosseveien to pass over, and when it was completed the tracks and wiring could be installed. The tunnel became operational on 7 September 1958. The same day the old Bekkelaget Station closed and the new one opened and the old tracks were abandoned. Construction continued for another year with the demolishing of the old right-of-way and widening of Mosseveien. Total costs were 7.4 million kroner, of which NSBn paid 950,000.

line. The curvature made the Østfold Line 22.4 meters (73 ft) longer. As
Bekkelaget Station was located on the part of the line which would be bypassed, NSB proposed closing the station. Local residents protested and NSB agreed to build a new halt at the southern entrance of the tunnel, 460 meters (1,510 ft) south of the former station. The new station costs 340,000 kroner, and way paid jointly by NSB and Oslo Municipality. This station was ultimately closed on 29 May 1983.

Construction of the tunnel began on 14 April 1955 and was contracted to Brødrene Hauge. It was originally planned to be completed on 1 August 1956, but it soon proved impossible to follow the schedule. The rock was of poorer conditions than originally thought. The porous rock meant that there was a

The Østfold Line opened on 2 January 1879. Through
Bekkelaget it originally ran in a day section along a right-of-way slightly elevated above Mosseveien. A landslide took place on 7 October 1953, in which both part of the railway tracks and the road were caught. More than eighty people were in the
