Wikipedia (translated from Danish): As early as 1934, a landlord found wooden posts. Oak strips also appeared in 1953 in connection with the drainage of Ravning Enge. Finally, in 1959, a doctor with an interest in archaeology discovered the site. An actual archaeological excavation was first begun in 1972 when a landlord donated a piece of Kulstof 14 from the National Museum. The archaeological excavations between 1972 and 1982 were led by Museum Inspector Thorkild Ramskou of the National Museum and showed that the bridge itself had been preserved in the marshy meadowland. After the archaeological investigations were completed, the remains of the bridge were covered with earth to prevent them from being lost once the surface dried. Road remains were found on the north side of the bridge, and further up the wooded hill, a double hollow road, the same width as the bridge, was discovered. In an excavation in November 1996, archaeologists investigated how the northern part of the bridge was anchored to the land. Furthermore, the archaeologists determined the bridge's length to be 760 meters, with an uncertainty of a few meters.
