How to Solve a Bridge Puzzle

Every number in the grid represents an island, and each digit tells you the total number of bridges that connect to that island. Islands are connected to each other by either single or double bridges (double bridges count as 2 in the total count) in either a horizontal or vertical direction, and every island is reachable from every other island. Each puzzle can be solved using only spatial logic and reasoning. Good luck!
