Wells River Bridge: A History of Engineering and Resilience
The crossing at Wells River has long been a vital artery for transportation, evolving through various engineering designs to withstand the elements and meet the demands of rail and road traffic. From early 20th-century trusses to the enduring steel arch of today, the site reflects a century of structural adaptation.
The Early Era and the Ranger Bridge
The original Wells River Bridge was constructed in 1903, serving the dual purpose of carrying both rail and road traffic. However, as traffic needs evolved, the road traffic was rerouted in 1917 to a dedicated structure located just downstream.
This new crossing, known as the Ranger Bridge, was a three-span Warren deck truss—a design characterized by longitudinal trusses with diagonals forming equilateral triangles to distribute loads efficiently. Designed by John W. Storrs, the Ranger Bridge cost approximately $65,000 to construct, which equates to roughly $1,630,000 when adjusted for inflation. Despite its design, the bridge proved vulnerable to nature; a severe flood undermined and destroyed the structure in 1922.

The Rise of the Steel Arch
Following the destruction of the Ranger Bridge, a new design was commissioned to ensure greater stability. J. R. Worcester took on the design responsibilities, and the project was awarded to the Boston Bridge Company. This partnership was a proven one, as the same designer and builder had collaborated 18 years prior to create the Arch Bridge in Bellows Falls.
Completed in 1923, the current structure is a three-hinged steel arch bridge. This specific engineering style utilizes hinges at the supports and the crown of the arch, allowing the bridge to accommodate thermal expansion and slight settlement of the foundations without inducing internal stress that could lead to cracking.

To ensure the continued safety and longevity of the crossing, the bridge underwent a comprehensive rehabilitation process between 2001 and 2003.

Frequently Asked Questions
When was the original Wells River Bridge built?
The original bridge was constructed in 1903 to accommodate both rail and road traffic.
What happened to the Ranger Bridge?
The Ranger Bridge, a Warren deck truss designed by John W. Storrs, was destroyed in 1922 after a flood undermined the structure.
Who designed and built the current bridge?
The current bridge was designed by J. R. Worcester and constructed by the Boston Bridge Company.
What is a three-hinged steel arch bridge?
It is a bridge design that uses steel arches with hinges at the base and the peak, allowing the structure to flex slightly under temperature changes or ground movement without sustaining damage.
When was the most recent work done on the bridge?
The current bridge underwent rehabilitation between 2001 and 2003.
