Ecological Overpasses Unite Natural Parks, Preserve Species Like Bears and Deer, and Show How Canada Combines Road Safety with Sustainable Development

The construction of green overpasses in areas cut by highways has become an important solution to protect animals as well as people. In Canada, this model of infrastructure has become a trend because it helps reduce wildlife deaths in critical areas.

In Alberta, last year, the first large ecological bridge in the region was built. The expectation is to reduce animal collisions by up to 80% for those crossing busy roads.

This initiative reinforces how engineering works can be adapted to balance urban development and preservation.

Connection Between Natural Parks

The new structure connects the Bow Valley Provincial Park to the Banff National Park, considered a UNESCO World Heritage Site.

Before the construction, data from the Ontario Natural Center for Social Development indicated that an animal died every 38 minutes due to being hit by vehicles nearby.

These accidents not only affected ecological balance but also incurred huge financial costs.

The annual loss reached 144 million dollars, an amount that weighed on public coffers. Therefore, investment in sustainable solutions proved necessary.

“We take pride in having increased road safety and environmental preservation with the implementation of seven overpasses of this size in Canada,” highlighted Neil Robson, project manager at Dialog, the firm responsible for the work.

Structure Designed for Wildlife

The bridge was designed to facilitate the movement of species such as moose, deer, grizzly bears, black bears, wolves, and bighorn sheep.

Due to this diversity, the location was chosen for the intervention, which now enhances its natural function as an ecological corridor.

The project includes two arches, each crossing two lanes, in addition to landscape areas compatible with the local vegetation.

There are also fences that guide animals to the safe crossing point. The total cost of construction was 12.6 million dollars.

New Overpass in British Columbia

Another recent project was inaugurated south of Radium Hot Springs, in British Columbia. With a width of 30 meters and a structure made of steel and concrete, the bridge over Highway 93/95 was successfully completed.

The difference lies in the fencing that extends for six kilometers, with gates that direct wildlife to the overpass.

In this way, animals are not exposed to traffic. The investment was 4.18 million dollars, further demonstrating Canada’s commitment to sustainability.

Comparisons with Brazil

While Canada invests in large wildlife corridors that connect areas of international natural importance, Brazil also has examples of urban integration between green fragments.

In São Paulo, Ibirapuera Park and Aclimação Park are linked by vegetation corridors that function as ecological passages.

However, these structures face constant threats. The Sena Madureira tunnel project, for example, plans to fell trees that are part of this corridor.

The Public Prosecutor’s Office recommended a more detailed analysis precisely because it recognized the environmental relevance of the species present.

Sustainable Development on the Agenda

The Canadian experiences clearly illustrate the importance of prioritizing the balance between urban progress and environmental conservation.

Because, in addition to saving animal lives, these constructions also prevent serious accidents for drivers and reduce public costs.

Therefore, investing in green overpasses is not just a matter of wildlife protection, but also of road safety and sustainable planning.

Canada shows that it is possible to reconcile large works with respect for the environment, serving as an example for other countries.

Pernambuco paradise with 59% of preserved area advances with R$ 2 billion in e-methanol, aims for 900 tons/day, grows 38.6% and builds electrified terminal of 400 thousand TEUs.

Brazil may have railways back on the map, but it will need the government: a study reveals 7,412 km ready for reactivation, a cost of R$ 75 billion, 61 sections analyzed, and none viable without public funding.
