Project Description & History

The I-84 Danbury Project is a Connecticut Department of Transportation (CTDOT) initiative to improve safety, increase capacity, and improve access and operations on Interstate 84 between Exits 3 and 8 in Danbury.

Project goals and considerations include connecting the City of Danbury with regional destinations, improving multimodal connections, and improving local and regional commerce and freight mobility.

There is significant congestion on I-84 in Danbury. Danbury is the western gateway into Connecticut and this stretch of I-84 carries substantial interstate traffic including a high percentage of commercial vehicles destined for markets in CT, the Boston metropolitan area and greater New England.

Improving traffic flow on I-84 in Danbury will have positive effects on commerce and freight mobility for the region and entire state.

The I-84 Danbury Project was identified as a high priority as part of the Let’s GO CT! vision, the Governor’s $100 billion, 30-year transportation investment plan to address preservation needs and enhancements that would contribute to economic progress.

Past Studies


2000

In 2000, CTDOT released the I-84 Corridor Deficiencies/Needs Study, focused on Exits 1 to 11. Recommendations in the final report relevant to Danbury were safety improvements for acceleration and deceleration lanes, local road improvements, widening and improving lane continuity at Exits 3-4 and 7-8, and increased capacity on the mainline with significant interchange and access improvements between Exits 3 and 8.


2009 – 2011

Between 2009 and 2011, CTDOT was preparing a draft Environmental Impact Statement & Environmental Evaluation for capacity improvements on I-84 between New York and Waterbury. However, no further action was taken due to lack of funding.
