THE BRONX - Pop-up wetlands are being built near the Bronx Terminal Market.

It's the first time pop-up wetlands have been built in New York City near elevated highways.

The wetlands will take in rain water that comes off the Deegan Expressway where it will be filtered. The water will help sustain plant life, reduce standing water that attracts mosquitoes and reduce polluted water that goes into Harlem.

The wetland project will be monitored for one year. Future wetlands will be built depending on the results of the project.
