The long range plan to bring Interstate 84 into the 21st century with three lanes in both directions from exits 3 through 8 is moving to the next review stage after engineers decided to fix traffic snarls on the west side and the east end with new ramps and new roads. Two of the options the state Department of Transportation is considering to improve the center section of I-84 that serves the downtown would create direct access to Danbury Hospital via Tamarack Avenue or Great Plains Road. The third option, which the DOT is keeping open after conversations with Danbury officials, is to build a road parallel to I-84 that would lead to Main Street and North Street, and to build a ramp from North Street onto I-84 westbound. The open discussion about improvements to I-84 between exits 5 and 6 is continuing as the DOT prepares for the next stage of environmental review, which will take years to complete, according to its timeline. The overall project, which is not funded and is expected to cost billions, would not begin construction until the early 2030s. It would not be complete until the mid-2040s.
