# Bridges in Graph

In graph theory, a **bridge**, **isthmus**, **cut-edge**, or **cut arc** is an edge 
of a graph whose deletion increases its number of connected components. Equivalently, 
an edge is a bridge if and only if it is not contained in any cycle. A graph is said 
to be bridgeless or isthmus-free if it contains no bridges.
