Highway 637 is a secondary highway in the Canadian province of Ontario. Located in the Sudbury District, the highway connects Highway 69 to the primary townsite of Killarney, 67 kilometres away, and to Killarney Provincial Park.

The highway was constructed in 1962.^[1] Prior to its construction, the community of Killarney relied primarily on water transport via Georgian Bay and the North Channel.

S-Curve

Until 2010, the intersection of Highway 637 and Highway 69 was located along a sharp S-curve in Highway 69's alignment, which rendered the approaching intersection virtually invisible to northbound traffic.^[2] An ongoing series of fatal car accidents, which continued to occur even after the provincial government posted a special warning sign with flashing yellow lights on the curve, was cited by residents of the area as an important factor in favour of the northward extension of Highway 400 to Sudbury.^[2]

Construction is currently under way on a dual-phase realignment of Highway 69 at the curve. The first phase, which began in 2008 and opened to traffic on July 27, 2010,^[2] saw the first set of two lanes built along the future freeway alignment.^[3] The second phase, which began in 2009, will see the second set of lanes completed from Estaire through to Highway 64, with a full interchange in place at Highway 637 when the route is completed.^[4]

The former S-curve alignment of Highway 69 is now a local road named Murdock River Road; while this road will be reconnected to Highway 637 when the interchange with the new alignment of Highway 69 is completed, Murdock River Road is currently accessible only from its more southerly terminus.
