Community officials broke ground Monday on a project aimed at cutting noise pollution and beautifying the Grand Central Parkway.
Trees and shrubs will be planted on the eastbound and westbound sides from Utopia Parkway to 188th Street in Jamaica Estates.
Besides being a cosmetic improvement, the foliage will act as a sound barrier for homeowners living along the highway.
"The green wall will reduce the heat island effect, it will produce oxygen, it will absorb carbon dioxide. It will trap particulate matter on the leaf surface. It will provide a home for insects, for birds. It will raise property values. It will look beautiful in terms of colors of leaves and things like that," said Parks Commissioner Adrian Benepe.
Congressman Gary Ackerman secured $375,000 in federal funding for the trees earlier this spring.
The plantings count toward Mayor Michael Bloomberg's initiative to plant one million new trees throughout the five boroughs by 2017.
