Gov. Dannel P. Malloy wants to widen Interstate 95 to alleviate traffic congestion and commissioned a $1.2 million study to support the idea. But I found a similar study from 2004 — State Project No. 56-245, I-95 Commuter Shoulders — that looked at the idea and rejected it for a number of reasons. Trust me, it wasn’t easy to get hold of the earlier study. I knew it existed, but somehow it had disappeared from the state Department of Transportation website.
