MTO Road Construction Project

​Essa Road Interchange & Highway 400 Overpass Replacement

The Ministry of Transportation (MTO) will be constructing a new interchange at Essa Road and Highway 400, while also widening Essa Road to six lanes.

This construction project is being led by the Ontario Ministry of Transportation (MTO) and includes significant roadwork on highway 400, between Harvie Road and Tiffin Road, along with a widening of Essa Road to six lanes between Fairview Rd and Bryne Dr/Ardagh Dr.

Project Update

June 2022

Construction is underway. The MTO has hired Aecon Construction and Materials Ltd. (Aecon) to complete the construction of the Essa Road Interchange Project. 

Starting June 15, traffic on Essa Road under the Highway 400 will be restricted to one lane in each direction. The access road that runs along the Highway 400 south of Essa Road will also be closed starting June 20, 2022 until the end of Fall 2022, and the Car Pool Lot at the northeast corner of Essa Road and Highway 400 will be closed until the end of 2024. An alternative lot can be found at the northwest corner of Ardagh Dr and Essa Road.

Starting June 20, 2022, pedestrian access will be restricted under the Highway 400. While the sidewalk along Essa Road is closed, a regularly scheduled Barrie Transit bus will bring pedestrians through the work zone for free. Pedestrians can get on the bus at bus stop 296 and 300 to the east and west of the construction limits and it will bring them to the other side. This service is expected to be in place until the end of 2024.​

Full closures underneath the Highway 400 along Essa Road will be required on three occasions to allow for the construction of new bridge girders and the demolition of the old bridge. The City will communicate these closures in a advance.

Full ramp terminal closures will also be implemented for a period of 5 days to allow for interchange ramps to connect to Essa Road. During this time access along Essa Road will still remain. A staging schematic is provided for reference. Detours will be in place for this project The City will communicate which traffic stage configuration is to be expected one week in advance of its implementation.

Previous Updates

April 2022

Pre-construction activities are on-going along Highway 400, Essa Rd and Bryne Dr. These activities include tree clearing and utility relocations. The Ministry of Transportation (MTO) has completed the tendering for the construction of the interchange and is expected to award the contract to the selected Contractor in the coming months. Construction activities will follow shortly after.

February 2022

The Ministry of Transportation (MTO) has released the construction tender for this project.  They are expected to hire a Contractor in spring 2022 followed immediately by the construction start.

During construction, pedestrian access under the Highway 400 will be restricted. The MTO in conjunction with the City of Barrie Transit department will be providing a free shuttle service for pedestrians who wish to cross the Highway 400 while access is restricted. More details on this shuttle service will follow in the coming months.

Please monitor this webpage for information on pedestrian and traffic impact updates.


Project Coordination

MTO is the proponent for this project, however the City is a key stakeholder. The City and MTO are working collaboratively to incorporate transportation improvements that support the needs of both local residents and the travelling public at large. These improvements will enhance the transportation network and help mitigate traffic congestion.

City Infrastructure Impacts

  • Highway crossing widening (widening from 4 lanes to 6 lanes from Bryne Drive to east of Fairview Road)
  • Multi-use Path on the north side of the road from Bryne Drive to east of Fairview Road
  • Sidewalk on the south side.

Impacts to Vehicular Traffic

This construction project involves a complex traffic staging plan. The project will be in the Stage 1A stage starting July 7th. A schematic of what can be expected during this stage is available.

Impacts to Pedestrian Traffic

Starting June 20, 2022 pedestrian access will be restricted under the Highway 400. Due to the closure of the sidewalk along Essa Road during construction, the City is planning to use the regular Barrie Transit service to convey pedestrians through the work zone at now charge, by picking up pedestrians at the nearest bus stop to the east and west of the construction limits and dropping them on the other side. This is expected to be in place until the end of 2024.

Project Scheduling

Detailed design was initiated in 2019. The City is anticipating construction to begin in the early 2020’s. Please refer to the MTO’s project website for the most current information regarding project scheduling.​
