> However, there are only 24 permanent residents and five active farms on Hamnøya. Therefore, there is regular transport of tankers, concentrate feed and livestock trucks.

From https://en.wikipedia.org/wiki/Hamn%C3%B8ya,_Vevelstad

> Hamnøya is an island in Vevelstad Municipality in Nordland county, Norway. The 16.6-square-kilometre (6.4 sq mi) island lies about 500 to 700 metres (0.3 to 0.4 mi) off shore from the mainland of the municipality, separated by the Vevelstadsundet strait. The island is only accessible by boat and in 2021 it had 35 permanent residents living on the island.

I'm not sure if it's cheaper to upgrade both posts, but a bridge doesn't look so silly.
