The Federal Railroad Administration is considering a new Amtrak route in an effort to alleviate congestion from the Northeast Corridor.

The new route would extend from New York City through Floral Park, to Port Jefferson, under the Long Island Sound, and up to Boston.

According to federal officials, the route would include new and existing trenches and tunnels, embankments and aerial structures.

The Northeast Corridor Joint Program Manager Rebecca Reyes-Alicea says the current Amtrak route from Washington, D.C. to Boston is more than 100 years old. She says the cost of the project could potentially be $290 billion.

"The cost of doing nothing is so significant," says Reyes-Alicea.

The plan involving a Long Island route is one of three plans proposed for the Northeast Corridor. If adopted, it wouldn't be complete until 2040.
