The Chattanooga Convention and Trade Center is solidly booked by groups who return to the city year after year for a good time and a great facility that has recently been expanded. Public entities and private citizens worked together to build the 20,000 seat Max Finley Stadium completed in 1998. The city and county have developed an extensive greenway system which includes 5 miles of constructed riverwalk beginning downtown and meandering through the historic art district and several parks. The city supports a downtown shuttle fleet of zero-emission electric buses – manufactured here in Chattanooga – for commuters and visitors wishing to park-and-ride.
