Downtown Houston Tunnel System
Houston, Harris County, Texas, 77010
The Houston tunnel system is a network of subterranean, climate-controlled, pedestrian walkways that links 95 full city blocks 20 feet (6 m) below Houston's downtown streets.
It is approximately 6 miles (9.7 km) long.
The Tunnel is a series of underground passageways that, with above-ground skywalks, link office towers to hotels, banks, corporate and government offices, restaurants, retail stores, and the Houston Theater District. Portions of the tunnel contain gift shops, newsstands, banks, technology centers, flower shops, copy centers, dry cleaners, and food courts similar to a major shopping mall. They are widely and heavily used by office workers and tourists.
Only two buildings, Wells Fargo Plaza and McKinney Garage on Main, offer direct access from the street to the Tunnel; other entry points are from street-level stairs, escalators, and elevators inside buildings that are connected to the tunnel. Access is allowed to the general public into these buildings with few restrictions, during normal operating hours, in order to reach the Tunnel.
Most of the retail areas of the Tunnel are in the basements of these buildings, connected by passageways. While walking through, one can determine which building they are in by the unique signage and/or architectural design of that building, as well as the wayfinding system and Houston Tunnel maps.
