Q: Context: The vast majority of the original bridge still exists, although the swing span has been removed. The 2.2-mile section to Pigeon Key, used as a fishing pier and long open to motorized vehicles to give access to the key, was closed to motorized traffic in 2008 after the unsupported sections began to sag. As of 2015, the section remains open to pedestrians and bicyclists. In 2014, Florida Department of Transportation approved a $77 million plan to restore the old bridge.
