Available studies and reports: Eastern Bridge in the National Capital Region

These reports summarize the findings of an investigation conducted along the Montée Paiement-Aviation Parkway, Lower Duck Island and McLaurin Bay corridors in the Ottawa River area to evaluate the subsurface soil and bedrock conditions. The investigation was limited to within the Ottawa River, and did not extend to the land approaches or islands. Distinct reports were prepared for each option. Available in both English and French.

• 6th Crossing Geotechnical Investigation – Kettle Island Alignment – Geotechnical Data Report (GDR)
• 6th Crossing Geotechnical Investigation – Lower Duck Island Alignment – Geotechnical Data Report (GDR)
• 6th Crossing Geotechnical Investigation – McLaurin Bay Alignment – Geotechnical Data Report (GDR)

These documents present engineering guidelines on the geotechnical design aspects of the project. They include construction considerations, which could influence planning and design decisions. They also analyse and interpret the information gathered during the geotechnical investigation, and give recommendations for the proposed crossing. Distinct reports were prepared for each option. Available in both English and French.

This report presents the findings for a refresh of the 2013 Functional Designs for an additional interprovincial bridge. A functional design is a long-term planning tool that enables the scoping of property acquisition and right-of-way needs, facilitates the identification of utility conflicts, highlights connections to and conflicts with existing transportation infrastructure and establishes a basis for refining high-level cost estimates. As the project proceeds, the functional design will evolve using post-pandemic data. Available in both English and French.

This report presents the refresh of the 2013 findings of our additional desktop research, and provides comments and recommendations that may affect the conceptual design and construction of an additional bridge in the National Capital Region (NCR). Available in both English and French.

This report provides a refresh summary of the previously completed Hydrotechnical Assessment of Function Designs for Alternative Corridors (November 2012), commissioned by the National Capital Commission (NCC). It considers changes in the regulatory regime and in the approach to the previous hydrotechnical assessment. Available in both English and French.

This report refreshed the analysis of the short-listed corridors for an additional bridge in the NCR. It incorporated the 2020 refreshed studies conducted by the NCC. Available in both English and French.

The NCC has completed the refresh of the study (PDF) on 3 potential corridors previously identified as having the most potential.

This document provides an overview of the most relevant planning studies (PDF) and highlights how this information can be applied to the Eastern Bridge project.

The studies were refreshed from 2019 to 2024 with updated data from the:

• geotechnical study
• revised Long-Term Integrated Interprovincial Crossings Plan, which considered new information from the:
  • Origin-Destination Survey
  • Interprovincial Truck Mobility Data Collection

This document provides an overview of past technical studies (PDF) and highlights relevant conclusions for the Eastern Bridge project.

This report: Public participation round 1 summarizes the feedback from the public, advisory groups and other stakeholders from the first round of participation in summer 2025.
