I would offer that you do not need the bridges over the Serpentine Canal there. If they think in terms of punts/canoes/gondolas then bridges become superfluous for traffic over the larger canals. I would put in docks as points for ferries to cross.

Smaller canals would have bridges because it is easier to walk across than throw something to the other side but if you are using small boats as the main mode of transportation about the city then the main thoroughfare will need very high bridges to allow clearance to the traffic.

Just a thought as I look to see how I would go from place to place in the city.
