 On July 17 and 30 , 1958 , the Department of Highways assumed the West Side Road , constructed in the years prior by Welland County between Port Colborne and Welland . The old highway was turned back to the WCA on June 26 and September 4 of that same year . Highway 58 then entered Welland along what is now Prince Charles Drive , meeting and becoming concurrent with Highway 3A at Riverside Drive / Lincoln Street and then turning east along East Main Street . By 1960 , the Welland Bypass was completed along the routing of the former Niagara , St. Catharines and Toronto Railway interurban line – the final operating interurban railway in Canada , which ceased operations on the line on March 28 , 1959 . This rerouted the highway along what is now Prince Charles Drive northwest to Thorold Road , where it turned east to Niagara Street .
