PREVIOUSLY COMPLETED STUDIES
In 2004, a Preliminary Design Study and associated Transportation Environmental Study Report (TESR) was undertaken to document the required improvements and widening requirements along 30 km of Highway 400 from 1 km south of Highway 89 northerly to the Highway 400 junction at Highway 11. That study recommended an ultimate 10-lane cross-section for Highway 400.
In 2014, a subsequent Preliminary Design Study was undertaken to provide an update of the required widening improvements along the same stretch of Highway 400. The study included a review of the then-present (2013), short-term (2021), and long-term (2031) transportation planning horizons and examined the transportation problems, opportunities, and issues relating to the existing Highway 400 interchanges within the study area. This study reaffirmed the need for widening of the Highway 400 corridor to 10 lanes before the year 2031. An Addendum to the 2004 TESR was prepared and made available for public review for a period of 30 days, resulting in an approved plan (AECOM, 2017).
In 2018, The Ministry of Transportation of Ontario (MTO) retained McIntosh Perry Consulting Engineers Ltd. to complete the Detail Design and Class Environmental Assessment (Class EA) Study for the replacement of three bridges on Highway 400 at Dunlop Street, Anne Street and Sunnidale Road, including the reconstruction of the Dunlop Street and Highway 400 interchange.
