Manhattan has the High Line, and now, an idea of making a Low Line in the Bronx is gaining momentum. NY1's Erin Clarke filed the following report.

Every day, people walk right by or actually over a path that goes through tunnels under St. Mary's Park and snakes through more than 20 blocks in three Bronx neighborhoods, finally ending at the East River.

"There's all this space under there," said Ed Garcia Conde, a Melrose resident.

It's a space that became a drug den over the years.

"People with needles in their arms, thousands and thousands of hypodermic needles littering the tracks," Conde said.

Last month, after the mayor took a trip there, the site was quickly cleaned up, and access points were closed off.

Now that there's attention on the defunct portion of the old New York and Harlem Railroad line, folks in the Bronx are pushing for a project that's long been talked about.

"Why not there be some sort of a of Low Line-type of, like the High Line?" said Mychal Johnson, a member of South Bronx Unite.

On Monday, Bronx Borough President Ruben Diaz Jr. sent a letter to the mayor encouraging him to consider create this type of park in a developing neighborhood that lacks green space.

"When you look at all the development that's happening in Melrose with Via Verde, La Central right across the street, this would be an added ammenity," Diaz said.

Since 2004, when Hunter College student Cesar Yoc first suggested a greenway, there's been plenty of ideas about what it could look like.

"I proposed to convert this tunnel in this area into commercial and communal spaces," Yoc said.

"Some sort of a shuttle train that takes people from one spot to the next throughout this space underneath St Mary's Park to Port Morris," Johnson said.

"The Tunnel of Love, where he would dig a ditch and have, like, boats going back and forth," Conde said.

The major road block that any plan faces, though, is that freight railroad company CSX owns the abandoned line.

"If they've already neglected the property, if they've already allowed for this encampment of drug addiction and drug abuse to occur there, it sends a clear message to us that they're not interested in doing anything positive with it," Diaz said.

So the Bronx is saying "turn the land over" so it can be put to better use.
