County Road 350 () is a road in Heim Municipality in Trøndelag county, Norway.
The road branches off from European route E39 at the ÃÂ sletten farm in the village of Halsa and runs a short distance north to Halsa Church, and then north-northeast until it nears Klevset on the shore of SkÃÂ¥lvik Fjord. There it turns north-northwest and passes through Rabben and Setra before terminating at Korneset on the shore of Vinje Fjord, where a local road continues, circling around the Halsa Peninsula and eventually leading back to Halsa.
The county road and the smaller local road are also both named Halsavegen ().
