Members of the Danbury legislative delegation are touting $10 million in state bonding approved yesterday for the design and engineering to widen I-84 between exits 3 and 8.  Senator Julie Kushner says this represents advances and improvements in vital transportation infrastructure.  She notes that it's not just Danburians that depend on I-84 to access businesses and recreational opportunities. Kushner says 15-minute drives are transformed into 45-minute traffic jams on a daily basis, adding that fixing this bottle neck is long overdue.  Kushner noted that widening the highway has shown vital improvements in removing traffic snarls in Waterbury, among other Connecticut roadways.  Representative David Arconti says investments in the state's transportation infrastructure are long overdue and essential for commerce and anyone travelling on the roadway.
