 Fulfilling a long-held planning goal, Constitution Plaza is now connected to the river's edge via a new (also elevated) pedestrian space that crosses over (a vastly reconfigured) Interstate 91 to a large waterfront amphitheater and walkways up-and-down river, and then across the Connecticut River to East Hartford.Constitution Plaza is a fine example of mid-twentieth-century commercial design, created as a series of projects under the overall coordination of Hartford architect Charles DuBose, which has sustained minimal alterations since it was designed.Its three largest office towers showcase various styles of glass-and-spandrel panel systems, with the glass areas recently replaced with more reflective and energy-efficient systems.
