South Main Street Bridge Eco-Park

Bridge and water

Overview

City of Thorold initiated a Municipal Class Environmental Assessment (Class EA) study to address concerns related to the South Main Street Bridge and Pedestrian Linkage in the Port Robinson area. The Class EA was carried out as Schedule "B'' undertaking in accordance with the Municipal Class Environmental Assessment process, approved under the Ontario Environmental Assessment Act (1990). 

McIntosh Perry Consulting Engineers Ltd. was originally retained by the City to facilitate the Class EA to address the need of providing a safe and reliable pedestrian linkage between South Main St. and Cross St. in the Port Robinson community. Subsequent to the Class EA, City of Thorold retained the services of RJ Burnside to create a conceptual rendering of a proposed Port Robinson Ecological Park (Eco-Park) at the South Main Street Bridge general location. The creation of an ecological park provides an opportunity to enhance an existing ecological habitat and an abandoned bridge currently used as a popular fishing hole/walkway connecting communities across an old canal waterway known for its wildlife. The Eco-Park design has an opportunity to reinforce the vision and character of the neighbourhood, while maintaining the ecological connection and environmental sensitivities. 

The City of Thorold has commenced the detailed design phase for the South Main Street Bridge located in the Port Robinson. The proposed design will be based on the mutually agreed “Preferred Design Concept Plan/3D Rendering” between the residents and the City. The detail design will also be in line with the display slides presented in the September 27, 2023 Public Information Centre that was held at the Port Robinson Community Centre. 

Study Area
The bridge is located between Cross St. (north) and South Main Street (south) over the former Welland River, now a segmented watercourse within Port Robinson in the city of Thorold.

Geotechnical Investigation Update - February 26 to March 1, 2024

The South Main Street Bridge will be closed for a ground and underwater geotechnical investigation program. Geotechnical investigations are required to generate a detailed design recommendations for the bridge new foundations and superstructures. Completing the subsoil investigations will provide the required geotechnical information for the bridge and foundation detailed designs. The planned geotechnical investigation work along with all other field assessments will be conducted in a holistic manner to minimize damage to the ecosystem. A clearance from the Niagara Peninsula Conservation Authority (NPCA) has been obtained.
