Objective

Provide access in areas where water is regularly allowed to overflow as a control mechanism and be a permanent fixture in areas with weak ground.

Description

Floating roads are literally roads that float on the water. Ideally, they are flexible in both time and space. They do not only float but can also move to accommodate a changing water level. Instead of a fixed bridge it consists of a series of floating pontoons on which vehicles can drive. Elevated (or flood protected) roads are useful when a city is vulnerable for flooding. When regular roads are turned into rivers, the citizens can still evacuate using the elevated (or flood protected) roads.

Expected results

Reduce the vulnerability and negative impacts of flooding on transport routes.
