the arch were cast using similar climbing formwork, with concrete provided via a cable conveyor. The construction system had an hydraulic self climbing casting mould which was anchored to the most recently completed arch segment, and segments were added at a rate of about 1 per week (illustration showing process). Each segment used about 60 cubic meters of k70 class concrete, and there were about 50 segments per side. The arch itself is hollow, and has been provided with heating coils to keep it free from ice and snow build up as well as navigation lights and interior maintenance pathways (info taken from this PDF at the joint bridge info site). Once the arch was in place, the stays, temporary concrete stay towers and cable conveyors were removed, and the roadway segments added. Some were added in place, but the centre roadway section under the arch was floated in on barges, as a complete section, and raised into place. Old Svinesund Bridge The former Svinesund Bridge, inaugurated on 15 June 1946, , to the east, was renamed the Old Svinesund Bridge but is still in service as a complement to the new bridge. Heavy trucks (gross weight exceeding 3,500 kg / 7,700 lb) are no longer permitted on the old bridge now that the new one is available. A significant part of Norwegian trade in goods was carried by trucks crossing the bridge, which now travels on the new bridge. It was built during the war period 1939–1946. It was delayed because of the war and the fact that it was partly destroyed when lightning ignited explosives (1942), placed on the bridge as a defence measure.
