The project, announced two years ago, is called Hartford 400. It calls for the removal of the massive highway interchanges in Hartford and East Hartford, the construction of new bridges and tunnels, more parkland and the reconnection of North Hartford to downtown, among other things. It is a daunting endeavor: preliminary estimates predict it will take 15 years and cost $17 billion. But some of that money is in the till. The deadline for the Hartford project is 2035, The city’s 400th anniversary, hence the project’s name. It is an ambitious timeframe. Finally, it is ironic, or perhaps unfortunate, that if Hartford 400 moves ahead, the major infrastructure project of the 21st century in Greater Hartford will involve correcting the errors made in the 20th century’s biggest project. Said Larson: “We have to get it right this time.”
