Enhanced Civil Infrastructure

Improves several Civil Infrastructure gameplay elements incl. Roads, Canals, Mountain Tunnels, Military Engineers (and Bridges if installed).

Since it changes parts of "Port Lime – Bridge District", that mod is highly recommended, however it is not required.

##### DISCLAIMER #####
Some people have stated that "Port Lime – Bridge District" has some bugs that can break multiplayer games, so be aware if you play multiplayer.

• Improve unit mobility with roads
• Improve strategic naval mobility with more canals
• Increase the maintanance of Civil Infrastructure and add domestic trade route yields to convert gold into food, production and culture
• You can now build cities focused on providing food or production to your other cities through trade routes
• Make Military Engineer more useful by making things they improve more useful ("Enhanced Military Infrastructure" may come at some point)
