They should take down the 401/Allen Rd interchange, just convert it into a parclo. They should take down the flyover ramps and put traffic lights. There can be access from Allen south to 401 east via the Allen South-Yorkdale exit. And also take down the northbound access to 401 express lanes. It will reduce maintainance costs, and it will be a lot less confusing. Allen Road will never be extended to Gardiner, so might as well do it.
