Delaware River Viaduct

The Delaware River Viaduct is a concrete railroad bridge that crosses the Delaware River in Northampton County and consists of several large spans. The structure rests on massive piers driven into the riverbed, supporting trains as they travel across this important crossing.

Construction of this reinforced concrete structure began in 1908 and was completed in 1911 as part of a broader railroad expansion across the Northeast. Its completion opened a direct rail passage across the river in this strategically important region.

The viaduct represents a period of railroad expansion in the northeastern United States when companies invested in concrete infrastructure development.

The viaduct can be viewed from outside, with the best views available from the riverside path or nearby roads. For more detailed visits, check ahead for current access information since the structure remains in active railroad use.

The viaduct follows a straight alignment instead of the originally planned curve, which results in lower speed limits for passing trains. This design choice continues to influence how trains cross the bridge today.
