Crossover bridge

Crossover bridges are a large three-part section of Cardassian space stations such as Deep Space 9 that connect the Habitat ring to the docking ring.

Crossover bridges are composed of seventy percent rodinium, twenty-six percent kelindide and four percent toranium. 

Following the assassination of Shakaar Edon in 2376, Ro Laren ordered constant security patrols of the crossover bridges.
