AOC Addresses Tunnel Issues
Egress The tunnels are considered to be confined spaces that require regularly spaced emergency exits, or egresses.
Work is underway to install two new egresses in the tunnels, and AOC expects to install additional egresses to limit the distance between them to no more than 600 feet.
According to AOC officials, this work has taken longer and cost more than originally expected, in large part because of working conditions in the tunnels.
