King's Highway 404 - www.OntHighways.com

Highway 404 is effectively a northern extension of the Don Valley Parkway from Highway 401 northerly to Newmarket. For many years, the northern terminus of Highway 404 was located at Davis Drive in Newmarket. The MTO plans to extend Highway 404 northeasterly to Highway 12 just south of Beaverton in the future. The first 2 km extension in this project opened in 2002, and extended the highway northerly from Davis Drive to Green Lane. Construction began in 2007 with advanced structure work to extend the highway from Green Lane northerly to Ravenshoe Road. The MTO was hoping to have the highway completed to Ravenshoe Road late in 2012, however difficult soil conditions and utility relocations delayed the opening until September 17, 2014. No construction commitments have been made to extend the highway beyond Ravenshoe Road towards Highway 12.
