Route 340, also known as Road to the Isles, is a road in the Canadian province of Newfoundland and Labrador passing through the towns of Lewisporte, Summerford and Twillingate, all in The Isles of Notre Dame region of the province. The highway has a total length of and a speed limit in the range of 40–80 km/h depending on whether the road is passing through a settlement. As the route's alternate name implies, the Road to the Isles passes through several islands off the coast of the main island of Newfoundland, such as New World Island, Twillingate Islands and some uninhabited islands. Change Islands and Fogo Island are accessible by ferry via Route 331, which has a junction with Route 340. Route 340 is the only road connection that New World Island and Twillingate Islands have with the main island. Route description Route 340 begins at Notre Dame Junction, which is a nickname given to the route's interchange with Route 1 (the Trans-Canada Highway). Leading northward, the route passes through the town of Lewisporte, where it then continues by turning right at an intersection with Route 341. The route continues northeastward and passes through the shoreline communities of Michael's Harbour and Campbellton, where the route intersects Route 343. Continuing northeastward, the route also intersects Route 331. This route leads to ferries connecting Change Islands and Fogo Island with the main island. Route 340 then passes through the community of Boyd's Cove. Afterwards, the route leads northward through a series of causeways that connect the main island of Newfoundland with New World Island. While on New World Island, the route passes through the town of Summerford and intersects Route 344. Following that intersection, the route leads northward until passing through Virgin Arm, where it then intersects Route 345 and leads northeastward. It then passes by Dildo Run Provincial Park and through the communities of Fairbanks, Hillgrade and Newville. 1.5 km north of Newville, the route intersects Route 346 and then veers westward towards a causeway connecting New World Island to Twillingate Islands. After the causeway, the route immediately veers northward and passes through Purcell's Harbour and Little Harbour, where the route then veers northwestward. The route then passes through the town of Twillingate, where a left turn at a local intersection is required to remain on the route. Through the town, the route is largely residential and is called Main Street.
