Results The Big Dig had several main results: Reduced Traffic Congestion - Replaced the elevated highway with underground tunnels, easing downtown traffic. Improved City Aesthetics - Removed the unsightly elevated highway and created the Rose Kennedy Greenway. Better Connectivity Improved access to Logan Airport and other parts of the city. Higher Costs - The project ended up costing billions more than expected. Safety Concerns Structural issues, like leaks and a tunnel collapse, raised safety problems.
