Benefits:
An upgraded bridge will offer you the opportunity to increase your population when you collect from the bridge.

Players that have completed their bridge should see the Upgrade Arrow above bridge.


1. Click on arrow to see the list of materials needed to upgrade.
2. Once you have collected parts needed, select Finish Building.



After your first upgrade is complete, you will see a collection icon over your bridge along with another upgrade icon.



Each upgrade increases the amount population that can be added when you collect from your upgraded bridge.
