The Last Word: Project Director Milton Brooks on Dallas’ Five-Mile-Long Mill Creek Tunnel
by David Seeley | May 16, 2024
The $300 million Mill Creek Drainage Relief Tunnel being built under Dallas is five miles long, was excavated up to 38 feet tall and wide, and is described as "the largest hard-rock gripper tunnel in North America, the Western Hemisphere, and, we think, the world" in a city video. Designed to provide 100-year flood protection for nearly 2,200 commercial and residential properties in the East Dallas area, its official name is almost as long as the tunnel itself: The Mill Creek/Peaks Branch/State-Thomas (MCPBST) Drainage Relief Tunnel.
