Bridge Building is a useful advance generally achieved fairly early n a game of C-evo.

Its immediate value is the ability for your Settlers and similar units to build roads and later railroads on tiles that contain rivers. There is a high cost in construction time: 9 or more movement points above what the tile would take without a river.

An almost immediate value is the "Overweight" feature that can be built into the design of new ground units that have restricted movement and double maintenance cost but exceed the standard weight quota and are therefore stronger than their freer contemporaries.
