NEW YORK -- Federal regulators announced a key approval for a planned $10 billion train tunnel under the Hudson River.
 
About two and a half billion of that money will come from the federally funded $1 trillion infrastructure bill the rest has been committed from New York, New Jersey  and AMTRAK.

The existing tunnel is more than 110 years old and prone to problems and delays due to crumbling walls and aging signals and wiring which was accelerated in 2012 when it took on saltwater because of Superstorm Sandy.

Hundreds of trains and hundreds of thousands of passengers per day pass through the tunnel during normal times, and delays can ripple up and down the East Coast between Boston and Washington.

Under the Gateway project, the new tunnel would be built parallel to the existing tunnel and is expected to take up to seven years to complete.
