A new road near Pontypridd, UK obstructs the travels of dormice -- a mouse species that lives in the area. So to accommodate the dormice, the local government built wire mesh bridges that the rodents can use over the road:

The bridges consist of wire mesh tubes suspended between trees and tall poles.[...]
When completed, the tubes will be solid mesh to stop the dormice falling out.
As dormice live in trees as opposed to on the ground, their routes have to stretch between trees instead of along underpasses used by, for example, hedgehogs and badgers.

There is only one species of dormouse in the UK, so there is probably a strong argument for protective measures such as this. Ever looked at the actual costing for a highway? £190k is nothing anyway.
Someday soon there's going to be a big backlash when the "Humans First" movement takes off.
