Beginning in 2011, the E.C. Row Expressway west of Huron Church Road underwent a complete reconstruction as part of the $1.4 billion Herb Gray Parkway project which included a major realignment of of the eastbound carriageway between Matchette Road and Huron Church Road to allow for an extension of Highway 401 to travel within their median, while the westbound lanes of the E.C. Row remained largely unchanged except for the addition of streetlights. The project was completed on November 21, 2015 and allows E.C. Row traffic to connect with the bridge-bound portion of Highway 401 via slip ramps located east of Machete Road. The E.C. Row still lacks direct access to the London-bound portion of Highway 401, however, the completion of phase one of the Highway 401 extension (Herb Gray Parkway) means that the indirect connection using Huron Church Road has been reduced to a short distance (with one traffic light) between the Parclo A4 interchange with the E.C. Row and the slip ramps with Highway 401.
