the bridge should be designed as an arched bridge with two 35-meter-long spans. the arch should rise at least 5 meters from the base of the river, allowing for enough clearance for boats to pass underneath. the two sides of the bridge should be connected with a central pier at least 10 meters tall to provide additional support.
