Danbury has paved more than 21 miles of road in recent months.  Public Works Director Antonio Iadarola says this construction season has been a pretty remarkable year, possibly with the most amount of paving done in the city in a year.  Iadarola predicted Danbury would pave 12.3 miles of roadway, but bonding and budgeted funding helped exceed that expectation.  The city spent just under $7 million on paving.  About 13 miles of road were milled or reclaimed, while about 7.4 miles were treated with cape sealing. a process that gets another 10 years out of road.  Last year, the City Council approved $18.5 million for road improvements, including paving, as part of a larger borrowing package.
