the late-1950s resulted in a substantial alteration to the route of the latter. Highway2 originally followed what is now Lakeshore Drive, which was inundated in July 1958 by the rising waters of the seaway east of Morrisburg. Highway2 was rerouted along the former CN railway right-of-way (itself moved further inland) prior to the flooding, with the new alignment opening to traffic in May 1958. As a result, Highway31 was truncated by approximately . Originally, Highway31 entered into Winchester along St. Lawrence Street before turning west onto Main Street. As early as 1965, proposals for bypassing the village were raised. After lengthy delays over whether or not to cross a Canadian Pacific Railway line at-grade, among other issues, construction began on the bypass in 1972. Highway31 and Highway43 were rerouted on to the Winchester Bypass when it was opened on July30, 1974. Within Ottawa When Highway31 was extended to Ottawa in 1937, provincial jurisdiction ended at Billings Bridge, where Bank Street crossed the Rideau River and entered the city limits. The portion with Ottawa, which was maintained and signed under a Connecting Link agreement with the provincial government, initially followed Bank Street directly to the foot of Parliament Hill at Wellington Street. It became concurrent with Highways 17/15/16 north of Carling Avenue (renamed Glebe Avenue in 1974), and a secondary route of all four highways also followed Rideau Canal Drive (now the Queen Elizabeth Driveway) between Carling Avenue and Wellington Street via Elgin Street. The 1955 Ontario Road map shows a new routing through Ottawa for the first time, with all four concurrent highways turning east onto Rideau Canal Drive off Bank Street on the north side of the Rideau Canal. The 1956 edition of the map continues to show Highway31 also following Bank Street to Wellington Street in addition to the portion along Rideau Canal Drive. In the 1960 edition, both routes were removed and Highway31 was rerouted along Heron Road and Bronson Avenue to end at Highway17 at Carling Avenue. This was altered in the 1964 edition, as Highway17 was moved onto the partially-completed Queensway; Highway31 and 16 now continued from Carling Avenue north to the Bronson Avenue interchange (now Exit121A). It is unclear when Highway31 was signed north of the Queensway to the Quebec boundary, but it is shown as the northern terminus in the 1989 Highways Distance Tables.
