Ideas to make bridges on top of rivers be a viable build option for villagers

How would you see this become a viable option? I have some ideas

  • Add patrol in movements to be able to scout for bridges
  • You have to work on the bridge on both ends, which means you can’t sneak in a bridge, keeping the shallow water a useful part of the map
  • Wooden bridges can only handle Infantry while Stone bridges can handle anything.
  • Go a step further and make it an option to build longer bridges, acting as a wall when firing on enemies below but you are also vulnerable in case a bombard was to appear and destroy that bridge

Or not make bridges an option but:

  • More generated bridges on the map that you can destroy and repair
  • Light units can swim across rivers but their movement speed, defense and sight are reduced in water

I vote first option. Look cool
