Under study since 2007, the deepening of New Haven Harbor is expected to get final approval by the U.S. Army Corps next month now that the state has agreed to bond its $25 million share of the major project’s cost. The cost is $72.311 million, with 75 percent of that picked up by the federal government. The project calls for 4.28 million cubic yards of silt, mostly glacially deposited, to be removed from the channel and deposited in several open-water sites within the harbor and Long Island Sound.
