Third Crossing of the Cataraqui River EA

City of Kingston

Project Details

This Class Environmental Assessment (EA) evaluated the need for and feasibility of implementing additional transportation capacity across the Cataraqui River in the City of Kingston. The study area extended along the shoreline of the Cataraqui River from the LaSalle Causeway-Highway 2 crossing in the city’s downtown area in the south to the Highway 401 crossing, 6 km to the north.

As prime consultant providing project management, civil engineering, and planning services, our team was supported by 14 firms with expertise in bridge and transportation engineering, geotechnical, geo-environmental, hydrogeological engineering, bridge architecture, cultural and archaeological heritage, ecology, noise assessment, and public consultation. The project followed Ontario’s Municipal Schedule C Class EA process. Since the riverbed in the EA study area is owned by the Federal Government, the EA also addressed the Federal EA framework (until Federal changes to the Canadian Environmental Assessment Act in 2012 suspended this requirement).

The EA was conducted in two stages. Stage 1 focused on a needs analysis and crossing options, and resulted in recommendations for a bridge crossing at John Counter Boulevard and Gore Road.  Stage 2 focused on three bridge designs, shoreland road and landscape designs, mitigation measures, capital and maintenance costs, and the Environmental Study Report. The opinion of probable cost for the preferred bridge design solution ranged from $120M for a two-lane option to $195M for a four-lane option.

In response to the four Part II Order requests that were filed after Kingston’s City Council had approved the EA, the Ministry of the Environment (MOE) ordered that an individual EA was not required, and that the project could proceed to the implementation phase. The city subsequently reviewed funding models for implementing the project.

The Third Crossing EA won an Award of Merit from Consulting Engineers of Ontario in 2014.
