'Highway 58' is a provincially maintained highway in the
Niagara Region in
Ontario,
Canada. Highway 58 currently runs from the
Highway 406 junction on the
St. Catharines/
Thorold border to the Highway 406 junction near
Turner's Corners. A second part runs from the
Highway 58A junction in the south of
Welland to the Niagara Road 3 junction in
Port Colborne. Prior to January 1998, Highway 58 was continuous as it travelled through west side of Welland before reaching the Highway 58A junction.
The segment between Highway 406 in Thorold and Niagara Road 57 east of Thorold is a four-lane freeway. It also contains the
Thorold Tunnel, one of the three
tunnels under the
Welland Canal.
Overall, the highway is 19.5 km (12 miles) in length. It is expected that a westward extension of
Highway 420 will assume the routing of the freeway portion of Highway 58 west of the Thorold Tunnel. Renumbering the freeway portion of the highway will reduce the total length of Highway 58 by about 4 km. No timeline has been set as of yet for the 420 extension.
Highway 58 is one of the few Ontario-maintained freeways that are not a part of the
400-Series Highway network. The speed limit along its length is 80 km/h (50 mph), low for a freeway. However, some sections are below the 400-Series standards; the interchange closest to the Thorold Tunnel has no acceleration lanes at all due to space constraints.
