Hi slownnsteady. The suspension cables on both bridges are just for looks; we "modeled" them after the golden gate bridge. A few more details: the top of the bridge was made of expanded steel for the weight and this material doesn't gets slippery with ice, and snow does'nt accumulate for additional weight. Also, the bridge itself is 120 feet, and with approaches it is 160 feet. The walking bridge is 140 feet. Thanks for viewing.
