A railroad crossing in Chappaqua is getting some changes after several car accidents have occurred at the location.

The New York state Department of Transportation has activated railroad preemption at a crossing sitting at the Saw Mill River Parkway at Roaring Brook Road. This means that when a train is detected, westbound traffic on Roaring Brook Road will have 34 seconds to clear the tracks.

After that time is up, the rest of the remaining time will be given to the Saw Mill River Parkway.

The signal then will not return to normal operation until the train clears the area completely.

Another part of the new signal pattern is eastbound motorists on Roaring Brook Road will not receive a green signal at all. This aims toprevent those drivers from being directed toward the train tracks.

Town of New Castle Deputy Supervisor Lisa Katz says the changes aren't enough. She wants to see a bridge be built over both the Saw Mill River Parkway and the Harlem Line of Metro-North Railroad.

Katz hopes that state and federal money will allow for a more permanent solution.
