Glue for Elevated bridge

Weldbond is good for a strong structure

Super Glue is good becasue it is fast-drying, and strong

CA is one of the best glues avaliable because it soaks right into the wood and creates a magnificent bond.

Elmer's Glue is bad becasue it takes a long time to glue and is not that strong. It also weighs a lot.

Hot glue is very heavy and bonds wear out after a while.

Wood glues are good for a light structure that has enough time to dry. Super Glue and CA are good becasue they are fast-usable glues and very strong.
