Double bridges/ land extension with bridges

Hello, Reddit community I just wanted to start posting unconventional and little known strategies. In today's post, I'm going to talk about bridges. Bridges are structures that can be built between two land tiles (including ice) in shallow water (light blue). In simple terms, a bridge is a road and can be built on your own and neutral territory. It can be crossed by water units and used for disembarking. It does not give any points, but can create a water connection to harbors. With a price of five stars it lies between roads and harbors.

Please write if you have any other ideas on how to use bridges.

I apologize in advance for any linguistic, content-related or tactical errors.
