The Oland Bridge is a road bridge connecting Kalmar on mainland Sweden to Färjestaden on the island of Oland to its east. At 6,072 meters (19,921 ft) long, it is one of the longest in all of Europe. It is supported by 156 pillars, and has a characteristic hump at its western end which was created to provide a vertical clearance of 36 m for shipping.
A little to the south of the western end of the bridge a small wooden pedestrian and bicycle bridge, around 150 m in length and connecting the island of Svino to the mainland, echoes the form of the Oland bridge. This "replica" is clearly visible to anyone crossing to Oland via the main bridge. While the Oresund Bridge linking Sweden with Denmark is longer overall, the Oland Bridge is the longest entirely in Swedish territory.
The Oland Bridge was inaugurated on 30 September 1972. Among the speakers at the ceremony, which took place on the island side of the bridge, were the Crown Prince (today king) Carl Gustaf. The bridge cost 80 million Swedish kronor to build. Construction took 4.5 years, and about 100,000 cubic meters of concrete was used. The bridge was also prepared for transporting fresh water from the mainland to Oland. The bridge project received much support, but there were also protests. The main objection was that the bridge would threaten the environment, possibly causing a huge influx of tourists to Oland and its vulnerable and precious nature.
