Fetsund Bridge

In 1860 - 1862 as part of the construction of the Kongsvingerbanen railway line a wooden bridge was built between the cities of Lillestrom and Kongsvinger . The work was led by Karl Abraham Piel . The grand opening took place on October 3, 1862 in the presence of King Charles XV , who walked across the bridge. The bridge was 449 m long, consisted of 69 spans of 5.7 m each, two spans of 19 m of iron beams on stone supports and one stone arch 7 m long ^{[1] [2] [3]} . On the lower side of the bridge, a carriageway for horse-drawn traffic and pedestrians was arranged. By the end of the 1860s. The question arose of reconstructing the bridge, since during floods, small spans created an obstacle during rafting , a large amount of wood accumulated in front of the bridge, which could damage the structure. In 1868 - 1869 part of the wooden spans were replaced by an iron arch truss with an opening of 37 m. In 1872 - 1877 . the remaining wooden spans were replaced by an iron grating truss with a length of 27.5 m on cast-iron supports, the number of spans decreased to 21. The work was carried out under the supervision of engineer Haakon Torp ( Norwegian Haakon Torp ), the total cost was 550 thousand crowns ^[3] .

In 1910, after a severe flood, it was decided to build a new high-water bridge several tens of meters upstream. Construction work began in 1912. Foundation work was carried out in the winter, when the water level was low. For pile driving, a steam driver was used. Span structures were assembled on the west bank of the river and then on pontoons delivered to the installation site. The weight of each span was about 250 tons, installation work was carried out from 1916 to 1918. ^[2] The bridge was opened to traffic on July 27, 1918. ^[4] The cost of the work amounted to 1.413 million kroons ^[3] . The old bridge was dismantled, part of the span structures was used for other bridges. The bridge was a combined road-rail, with one lane for cars on each side of the railway ^[5] . In 1959 , after the opening of the road bridge , car traffic was stopped. On the upper side of the bridge, a passage was arranged for pedestrians and cyclists ^[6] .

The bridge is seven-span, the spans are blocked by through metal arch trusses with a carriageway along the lower belt. The span is 60 m, the total length of the bridge is 424 m ^[7] . The bridge supports are made of cast concrete on a pile foundation, lined with natural stone ^[2] . Single track bridge. On the lower side of the bridge is a sidewalk.
