Class Environmental Assessment Highway 400 Bridge Rehabilitation for the Finch West LRT Project
Mosaic Transit Group is completing a Class Environmental Assessment (EA) for the rehabilitation of the bridge on Highway 400 at Finch Avenue West as part of the Finch West Light Rail Transit (LRT) project in Toronto. Mosaic Transit Group is the consortium selected by Metrolinx and Infrastructure Ontario to design, build, finance during construction and maintain the Finch West LRT project. Subject to approvals, bridge rehabilitation is planned for 2019 to 2020. The objective of the EA is to identify the key congestion areas and mitigate transportation issues.
The planned rehabilitation activities for the bridge on Highway 400 at Finch Avenue West will be performed using a Rapid Bridge Replacement (RBR) approach. In a traditional bridge replacement method, construction staging would require long duration lane reductions and diversions, whereas with the RBR approach, traffic disruptions to motorists would be reduced from many years to weekend and night lane closures. The bridge rehabilitation works planned for Spring 2020 include replacement of the bridge’s northbound and southbound superstructure replacements over separate weekends, including full closure of Highway 400 to traffic travelling in the direction of the portion of the bridge being replaced. In addition, the planned works will require the closure of on-ramps to Highway 400 and nearby Finch Avenue West during each of the two weekend operations.
Details on the rehabilitation along with traffic impacts will be available on the project website at www.mosaictransit.com. The website will be updated throughout the EA process.
This study is subject to Ontario’s Environmental Assessment Act and will be carried out in accordance with the requirements of the Class EA for Provincial Transportation Facilities (2000) (MTO’s Class EA) as a Group ‘B’ project. MTO’s Class EA allows a Group ‘B’ project to be “stepped down” to a Group ‘C’ project if there are no significant adverse environmental effects. Based on the findings of the study, MTO will decide if it is appropriate for the project to be “stepped down”. In the event a decision is made to step down the project, a notice will be issued to provide a 30-day public review periods.
Consultation with interested parties, including the public, businesses, regulatory and governmental agencies will form an integral part of this study to identify and address interests and concerns. In late Fall 2018, an open house will be held during the study to provide opportunities for members of the public to meet with the Project Team, learn about the study, and to provide feedback. Once details are confirmed, Mosaic Transit Group will publicly advertise the Open House in print media and at www.mosaictransit.com.
We are collecting comments and information regarding this project to assist MTO in meeting the requirements of the Environmental Assessment Act. This material will be maintained on file for use during the project and may be included in project documentation. Information collected will be used in accordance with the Freedom of Information and Protection of Privacy Act. Except for personal information, all comments will become part of the public record.
We are interested in hearing any comments you may have as early as possible as the study proceeds.
