It connects Auld's Cove at Trunk 4 with Boylston at Trunk 16.
Route 334 begins in Boylston, on route 16. At the beginning it travels east for about twenty kilometers, following the north shore to Chedabucto Bay, afterwards it turns northwest at Hadleyville, where it continues to follow the shore. It then follows the southwest shore of the Canso Strait, notably going to Mulgrave, a town adjacent to Port Hawkesbury. The route finishes at exit 40 (an intersection) of the Trans-Canada Highway, a multiplex of routes 104 and 4, barely 1 kilometer west of the Canso Causeway .
The section of the Collector Highway 344 from Auld's Cove and Mulgrave was designated as Trunk Highway 44.
