A walk on the wild side

The old pejorative ‘bridge and tunnel’ is taking on a new, less offensive meaning in Colombia. 

With Colombia’s 4G roads programme progressing, vehicles are achieving higher travel speeds than ever before on modernised roadways. The only problem is, the local wildlife had become accustomed to crossing the road at leisure. 

In response, the concessionaire on the Ruta del Sol project has come up with a solution to aid the daily commute of local possums, voles, foxes, snakes, frogs, iguanas, lizards, jaguars, anteaters, sloths and primates living near the second leg of the project between Puerto Salgar and San Roque: new suspended bridges and under-highway tunnels. 

In an effort to preserve the diversity of the native ecosystem, the concessionaire will deploy 28 tunnels and four bridges along the route in a move that the Agencia Nacional de Infraestructura has deemed “one of the most innovative projects within [an ANI] concession to date”. 

The cost of the added infrastructure was unspecified, but the benefits are clear—and in some cases, maybe even cuddly.
