overpass instead of sharing the existing overpass with westbound Highway 403 traffic. The existing bridges carrying QEW traffic across Ford Drive and the eastbound ramp to Highway 403 were demolished and replaced by new wider structures which can accommodate future HOV lanes and high-mast lighting. At the present Highway 403 only connects to the QEW west of the interchange, but a new set of flyover ramps are being proposed from Highway 403 to the QEW east of that junction using the existing right-of-way which would allow for a direct freeway connection from Milton to south Mississauga. The 2017 initial design of the Hurontario LRT line had it occupying the centre median of Hurontario Street including the existing bridge crossing Highway403. At the southern approach to the bridge, there would be a junction for an LRT branch to the Mississauga City Centre, and the junction would have crossed the southbound traffic lanes of Hurontario Street and a Highway403 exit ramp at grade. However studies showed that this initial LRT route would seriously impact vehicular traffic at the Highway403-Hurontario interchange. A revised 2021 route proposes that the LRT cross Highway403 on its own elevated guideway to the west of Hurontario Street overpass. There are preliminary proposals for adding HOV lanes to Highway403 within Burlington, alongside a proposal to modify the Freeman Interchange.
