Harbour with Six Lane Road and Footbridges.
The standard two lane road outside of the harbour was doing my head in!
I decided that the six lane two way road outside was the way to go. I added the two pedestrian footbridges as they allow you the flexibility to add bus routes at your own convenience without having to consider whether or not the pedestrians can access the buses.
Works well in my cities and I hope you find this asset useful.
