Description 

The Astoria Belt Line Bridge is a classic example of early 20th century reinforced concrete construction. The structure was completed to allow the city streets and eventual coast highway to cross over the railroad line that encircled most of Astoria.

The bridge featured many of the classic concrete construction details of the era including decorative railing, inset paneling and surface treatments. The retaining walls leading to the structure feature arched paneling providing the illusion of approach spans leading to the two main spans. The structure originally has decorative cast iron light posts attached to the rail, but these rails have since been removed.

The railroad that served the area along Youngs Bay was removed and the structure now serves as highway crossing over a local street. The structure is situated just a few yards north of the Old Youngs Bay Bridge on the US-101 business route.
