After more than two years, the state Department of Transportation project to expand North Street in Danbury is coming to an end point, though it's still several months away.  New stoplights will be turned on soon and work will end for the winter.  Final alignment of the new lanes should be completed before the shut down.  Paving crews won’t be able to put the final layer of asphalt down until the Spring.  Part of the delay on the project was  a large sewer line under North Street that had to be moved so a new retaining wall could be built.  Project manager John Dunham says there was also a lot of utility work needed.
