The state Department of Transportation is considering building a tunnel in Danbury to straighten Interstate 84 between Exits 2 and 4.  The project was highlighted in a tweet last week, amplified by one from former Mayor Mark Boughton.  The DOT says it's one option, but not considered viable. 

The project manager says nearly two dozen concepts have been examined.  The DOT Project website says cutting a tunnel under University Boulevard would not reduce congestion or improve mobility on the highway, recommending that this concept be dismissed from further consideration. 

This is part of long term plans to improve I-84 from the New York state line out to exit 8.
