Alversund Bridge is a suspension bridge spanning Alverstraumen, a narrow strait between the island of Radøy and Alversund, in Lindås municipality, Hordaland, Norway. The bridge was opened for traffic on 29 June 1958, and connected Radøy to the mainland. The Alversund bridge was the first toll bridge collaboration project between the municipalities in the region of Nordhordland. The bridge's main span is 198 meters and the maximum clearance to the sea is 27 metres.
It was decided that even when the bridge was paid for in 1968, the toll fees would continue as a prepayment for the planned Nordhordland Bridge (opened in 1994).
