Highway 20 is a highway in central Alberta, Canada, west of Highway 2.[1]
Highway 20 begins Highway 11 and travels north for along the east side of the town of Sylvan Lake to a roundabout with Highway 11A. It continues for to Highway 12 in Bentley, passing the southeastern shore of Sylvan Lake at Jarvis Bay as well as the Jarvis Bay Provincial Park. It intersects Highway 771 north of Bentley, which provides access to the west side of Gull Lake and Parkland Beach, and travels for in a northwesterly direction to Rimbey; Highway 20 bypasses Rimbey while Highway 20A is a business route through the town and connects with Highway 53 west. Highway 20 proceeds another before reconnecting with Highway 20A, and travels another to Highway 53 east, where it heads east towards Ponoka.
Highway 20 continues north for to Bluffton where Highway 607 branches off to the west, another north to Hoadley where Highway 611 branches off to the east, and another north to Winfield where it crosses Highway 13. From Winfield, the highway continues north for to Breton where it crosses Highway 616 before it travels another north Alsike where it ends at Highway 39.[2]
Highway 20 was originally a short, long highway that ran from Highway 11 in Sylvan Lake to the Highway 12 / Highway 51 intersection in Bentley. From this intersection, Highway 12 continued north to Rimbey, Breton, and Alsike. In the mid-1980s, when Highway 11 was realigned to bypass Sylvan Lake, Highway 20 was extended to the south to connect with the new alignment. In January 1988, the section of Highway 12 between Bentley and Alsike was redesignated as Highway 20, while Highway 51 was decommissioned and redesignated as the new western section of Highway 12.[3]
