Emergency dredging began Friday on the Moriches Inlet.
As News 12 has reported, powerful winter storms caused massive amounts of sand to pile up, making it dangerous and narrow for boaters.
The inlet was declared a hazard to life by federal officials.
A $10 million plan was approved by Washington to address the issue.
Officials say the work will be beneficial to water quality in the bay in addition to aiding navigation in the area.
The sand will be brought about 5 miles west to Smith Point Park and the TWA Flight 800 memorial to protect it from future storms.
