Wilton State Senator Toni Boucher is critical of a toll proposal up for a public hearing this week.  She notes that DOT Commissioner James Redeker is already on record saying that congestion tolling would make Connecticut the most heavily tolled state in the nation. She noted that the Yankee Institute estimated that the average cost of tolls to Connecticut drivers would be about $240 a month, on top of Connecticut having the sixth highest gas taxes in the country.
