When it opened in 1959, the original Central Artery comfortably carried about 75,000 vehicles a day. By the late 1980s, it carried upwards of 200,000, making it one of the most congested highways in the United States. This extraordinary traffic mess, often congested for 16 hours per day, represented a continuous economic and quality-of-life drain on Boston and New England.
