 In 1966, plans were made to make the portion of the Warren Street Bypass through the Glenside neighborhood of Reading limited-access by eliminating at-grade intersections with local streets, resulting in the streets coming to a dead end at the bypass.The more southerly route for the Warren Street Bypass extension between US 222 and Pricetown Road was selected by 1969.On November 15, 1975, the American Association of State Highway and Transportation Officials (AASHTO) approved for US 222 to be routed to bypass Reading, with the route following the Warren Street Bypass between US 422 in Wyomissing and Allentown Pike.
