9. Bradford Bypass Mainline Refinement – Holland River East Branch Crossing

2002 Approved EA Alignment

  • Follows the original alignment in the 2002 Approved EA.
  • Proposes twin structures for eastbound and westbound lanes.

Base Case from 2002 Approved EA Alignment

Refinement Alternative 1 – Curved Transition East of River Crossing

  • Bradford Bypass between Bathurst Street to east of Yonge Street is realigned by approximately 150m to the south.
  • Realignment transitions back to existing alignment just east of Yonge Street.
  • Proposes twin structures for eastbound and westbound lanes.
  • This proposed refinement alternative provides less impact to the meandering river.
  • Mitigates property impacts to Albert’s Marina and Silver Lakes Golf Course.
  • Impacts to residential land parcels at Yonge Street.
  • Additional property required beyond the 2002 Approved EA Right-of-Way.
  • Avoids Archaeological Site BAGV 42.

Refinement Alternative 2 – Tangent Transition East of River Crossing

  • Bradford Bypass between Bathurst Street to east of Yonge Street is realigned by approximately 150m to the south.
  • Realignment ties into the existing alignment 1km east of Yonge Street resulting in fewer curves.
  • Proposes twin structures for eastbound and westbound lanes.
  • This proposed refinement alternative provides less impact to the meandering river.
  • Mitigates property impacts to Albert’s Marina and Silver Lakes Golf Course.
  • Impacts to residential land parcels at Yonge Street.
  • Additional Property required beyond the 2002 Approved EA Right-of-Way.
  • Avoids Archaeological Site BAGV 42.

Key Considerations

Environmental

  • Archaeological Resources
  • Contamination (area of high potential contamination)
  • Fish and Fish Habitat (specialized habitat)
  • Groundwater (Highly Vulnerable Aquifers)
  • Land Use (Greenbelt, Holland Marsh Specialty Area)
  • Navigation (clearance requirements)
  • Surface Water and Fluvial Geomorphology (drainage, natural channel patterns)
  • Terrestrial Ecosystems (Provincially Significant Wetlands, Species at Risk)

Transportation & Engineering

Highway Design – Geometrics

  • Bradford Bypass between Bathurst Street to east of Yonge Street is realigned up to 150m south of the original alignment to facilitate structural/ foundations engineering.

Property Impacts

  • Lands required are beyond the Right-of-Way for the 2002 Approved EA Alignment.
  • Mitigates property impacts to Albert's Marina and Silver Lakes Golf Course.
  • Impacts to residential land parcels at Yonge Street.
