Drivers in the Danbury area have noticed a big change in scenery around the exit 7 area along I-84.  The state Department of Transportation has cleared trees from the median and sides of the road.  Drivers have been stuck in traffic because of the lane closures for that work.  DOT Spokesman Kevin Nursik says some trees have been damaged by Emerald Ash Borer and Gypsy Moths, others were compromised by the 2018 macroburst.  But he says others were cleared to improve sight lines.  He says the goal is to have a 30-foot clear zone on either side of the highway, which is why clearing is now happening closer to exit 6.
