The Ontario Ministry of Transportation (MTO) retained Stantec Consulting Ltd. to undertake the Detail Design and Class Environmental Assessment (Class EA) Study for the reconstruction of the Highway 400 and Essa Road interchange, including the replacement of the Highway 400 overpass structures at Essa Road. The study area is within the City of Barrie.
The Preliminary Design of the project was documented in the Highway 400 Improvements from 1 km South of Highway 89 to the Junction of Highway 11 Transportation Environmental Study Report, 2004 (TESR) and TESR Addendum, 2017, to update the study (W.O. 06-20016). The TESR received Environmental Assessment (EA) clearance in 2006 and the TESR Addendum received EA clearance in 2017.
The Detail Design study is underway and will build upon the recommendations from the Preliminary Design study to finalize the design details for the interchange improvements. Investigations will be undertaken throughout Detail Design to identify the existing environmental conditions, design features, detours and construction staging, impacts, and mitigation measures for the Design. This information will be documented in a Design and Construction Report (DCR) at the end of the study. You are encouraged to participate in the project and to provide comments in writing to the project team. If you wish to have your name added to the project mailing list, please contact the project team.
This website will be maintained for the duration of the study and updated as new information becomes available.
