Congestion, coupled with the perceived need to compete with flourishing suburbs, prompted Boston and cities around the nation to create urban freeways.
New York City master builder Robert Moses established the model with highways like the Cross Bronx Expressway, and Boston eagerly followed the game plan with the construction of Interstate 93 through downtown. The elevated six-lane Central Artery, which opened inlinked the Southeast Expressway with points north, with plentiful offramps to access the city and its proliferation of above-ground parking garages.

Looking at the new roadway system by itself, the Central Artery and Tunnel project is solving that problem, with capacity to spare. It handles aboutvehicles each weekday.
Bottlenecks are minimized through the use of the add-a-lane design, where onramps become a permanent additional lane, requiring less merging. Advertisement There are caveats.
The theory of induced demand — that as more highway lanes are built, more traffic will come to fill them — has played out as predicted, particularly at the Ted Williams Tunnel, where traffic typically stacks up every evening trying to get to East Boston, Logan, and points north.
A Boston Globe analysis found that while traffic was moving better in the core, it was worse elsewhere.
