A major intersection in the Taku-Campbell neighborhood was closed late Tuesday after a fatal collision involving a train and a pedestrian. 

Anchorage Police said Arctic Boulevard was closed in both directions at the Dowling Road overpass; the train is stopped in the northbound lane. About three hours after the initial release from APD. Around 12:15 a.m. Wednesday morning, Arctic reopened in both directions. 

Drivers were asked to avoid the area and seek alternate routes, as the intersection will be closed for several hours. 

The deceased has only been identified as a woman. 

According to an APD spokesperson, the woman was on the tracks south of the Dowling overpass between C Street and Arctic when she was struck. It's not yet clear what she was doing at the time of the collision.

Alaska Railroad spokesperson Tim Sullivan said the train sounded the horn and immediately put on the brakes. It came to a stop as soon as it was able -- blocking the intersection at Arctic Boulevard. The train was traveling 34 mph. Sullivan said at that speed, it takes several hundred yards to come to a complete stop.

"They only saw her moments before impact," he added.

Anchorage Police and Alaska Railroad Police are continuing a joint investigation.

Sullivan said this is the third fatality in two years that has happened on Alaska Railroad tracks. He said it is the fourteenth since 1985.
