History of Secondary Highway 661:
Secondary Highway 661 is a local highway in the District of Sudbury that serves as an access road from Highway 144 to Gogama, located south of Timmins. The route was first designated as a Secondary Highway by an Order-in-Council, effective January 11, 1968. As originally designated, Highway 661 extended from Highway 144 to the CNR crossing in the town centre. From there, Highway 661 continued through Gogama along a portion of the bypassed route of Highway 560, which had previously served as the main access road into Gogama before the arrival of Highway 144. Highway 661 followed Miller Street from the CNR crossing to Pine Street, where the route turned right. At the end of Pine Street, Highway 661 turned left onto Hazel Street. The route reached its eastern terminus at the former entrance to Gogama, located at the intersection of Hazel Street and Cedar Street. The route of Highway 661 has not changed since the highway was first established in 1968. Highway 661 is paved for its entire length. Unless posted otherwise, the speed limit on Highway 661 is 80 km/h (50 mph). Services are available in Gogama.
