The four lane[2] 14th Street Viaduct begins at the intersection of Willow Avenue, and travels perpendicular to the Hudson Palisades in Union City.

Portions of the massive retaining wall were originally parts of the North Hudson County Railway's Hillside Line.

Just north of its lower end is the Willow Avenue Viaduct, which travels over the Hudson Bergen Light Rail and serves local as well as Lincoln Tunnel-bound traffic.

[2] Plans were unveiled for improvements to the area beneath the bridge on September 7, 2010, which include a dog run, playground, raised sidewalks and narrower streets for improved pedestrian safety, a block of active recreation space with a multi-use court and two blocks of multi-purpose space that can be used for farmer's markets and other community purposes.

The plans were part of a $55 million federally funded improvement project for Hudson County that was spurred by the 2007 collapse of the I-35W Mississippi River bridge in Minneapolis, Minnesota.

[14] Operated by NY Waterway, daily service runs to the West Midtown Ferry Terminal (with some trips via Lincoln Harbor),[15] and additional weekday peak service runs to the Battery Park City and Wall Street ferry terminals.
