context_page_description: King's Highway 58A, commonly referred to as Highway 58A, is a provincially maintained highway in the Canadian province of Ontario. The short route serves to connect Highway 58 with Highway 140 and passes beneath the Welland Canal through the Townline Tunnel. The entire route is located within the city of Welland in the Regional Municipality of Niagara.
  The route was established by 1978, following completion of the Welland By-Pass project, and has remained unchanged since then.
context_section_description: Highway 58A passes through the Townline Tunnel, one of the three tunnels under the Welland Canal. The majority of the route follows Townline Road, although a short section at the eastern end travels along Reaker Road and Netherby Road. Beginning at the northern terminus of the southern section of Highway 58, the highway travels east, parallel with two railway lines. The road intersects Canal Bank Road (north) / The Kingsway (south) after crossing an earth plug on the old Welland Canal, now the Welland Recreational Waterway. It then curves slightly southwards and begins descending towards the Townline Tunnel. It encounters Humberstone Road and then passes beneath a railway prior to entering the tunnel. At the eastern end of the tunnel, the route encounters Rusholme Road before passing beneath Highway 140. It turns north onto Reaker Road and then west onto Netherby Road to end at an at-grade intersection with Highway 140.
