Too Many Culverts, Not Enough Bridges
The 16 kilometre (km) eastern extension of the Highway 407 only bridges several of the 27 Rouge, Petticoat and Duffin's Creek wildlife corridors between Highway 48 in Markham and Brock Road in Pickering.
Twenty Wildlife Corridors Cut
The remaining 20 streams and wildlife corridors have been severed and buried in long pipes beneath the highway, creating dead-ends for pedestrian, bicycle and wildlife movement.
The private international 407 consortium used culverts instead of bridges. This decision saved private money but it will increase public costs in the long term.
Costly Deer Car Collisions Increase
During one month in the fall of 2003, more than five deer-car collisions occurred. Wildlife are being killed, human lives are being endangered, traffic jams are being created, and insurance and health care costs are soaring.
Additional bridges are needed to allow the safe passage of people, wildlife and fish along the north-south stream and wildlife corridors that Hwy 407 and other GTA roads and highways cross.
Why build bridges instead of culverts?
1. Avoid costly and potentially deadly collisions between hikers, bicyclists, deer and traffic;
2. Protect linkages and movement between upstream and downstream fish and wildlife habitat;
3. Allow safe movement along trails linking the Waterfront Trail to the ORM & Cross Canada Trail;
4. Plan ahead to avoid the need for costly and disruptive retrofits to re-establish safe corridors;
5. Avoid the creation of "islands of green" that cannot sustain their beauty or biological diversity.
