The state plans to replace the superstructures of two Interstate 84 bridges near the Danbury Fair mall as soon as 2029 as part of a $138 million upgrade of the highway from the New York border to Exit 4. The bridges in question at eastbound Exit 3 carry a daily average of 81,000 eastbound motorists and an average of 40,000 westbound motorists, according to the DOT’s latest publicly available traffic data. Moreover, the bridges are in one of the most problematic sections of I-84 in Danbury, where daily rush-hour backups are the norm. Left exit ramps and other design flaws are the target of a larger, long-term project called I-84 Danbury to widen and straighten the highway from exits 1 through 8. The ambitious project, with a price tag of $3 billion to $4 billion, is not expected to begin construction for at least a decade, and it is not expected to be complete until the mid- to late 2040s.
