GREEN POINT - Officials say 140 trees are coming down in Brooklyn and Queens this month as the state Department of Transportation prepares to replace the Kosciuszko Bridge. 

However, officials say they are making sure that they're doing it in an eco-friendly way.

The trees are being removed to protect an endangered bat population, which nests in trees in the area. The bats are in hibernation at the moment, so it's the safest time to remove the trees.

Officials from the DOT say that 300 additional trees will be planted to replace the ones that they removed.

The project director from the DOT says the plans for the new bridge are 12 years in the making. The new bridge will have an updated design and will improve traffic flow.

Bridge construction is expected to start later this year. The new Kosciuszko Bridge should be completed by 2018.
