Abstract
Suppose $ch(G)$ and $\chi(G)$ denote, respectively, the choice number and the chromatic number of a graph $G=(V,E)$. If $ch(G)=\chi(G)$, then $G$ is said to be chromatic-choosable. Here, we find the choice numbers of all multi-bridge or $l$-bridge graphs and classify those that are chromatic-choosable for all $l\ge 2$.
