 East of the Murphy Road overpass, Highway 402 was re-aligned to bypass the original interchange with Highway 40 constructed in 1963; Exmouth Street was redirected to connect with Highway 7 (London Line) at that Parclo A2 junction, and Quinn Street now follows the former alignment of the freeway.For the realigned Highway 402, a new Parclo B4 interchange was constructed with Highway 40 just north of the original interchange.During the late-1950s, the Saint Lawrence Seaway project created a navigable lock system between the Atlantic Ocean and Lake Superior, while simultaneously reclaiming properties along the shoreline to create a continuous parkway.
