Skarnsund

Skarnsund is a strait (sund) in central Norway. It is located in Trøndelag county, within the municipality of Inderøy, and forms a natural waterway that separates the Straumen area on the Inderøy peninsula from the outer coastal lands. The strait is primarily used for local coastal navigation and supports nearby fishing activities.

Geography and environment play a central role in Skarnsund. The waters are comparatively narrow and shallow, with tides and currents that influence local boating and fishing practices. The surrounding coast is characterized by a mix of farmland, small villages, and coastal scenery that attracts outdoor recreation and tourism.

A major infrastructure feature is the Skarnsund Bridge (Skarnsundsbrua), a cable-stayed bridge that spans the strait and carries the main road across it. The bridge opened in 1991, replacing a regular ferry service and greatly improving year-round connectivity for residents and businesses in the region. It is a recognizable landmark in Inderøy and a symbol of regional development.

Historically, crossing Skarnsund has been important for transport, trade, and fisheries in the area. The bridge and the associated road network have influenced local economics, settlement patterns, and tourism, while the strait itself remains an active part of the coastal landscape of Trøndelag.
