Ironton–Russell Bridge

The Ironton–Russell Bridge can refer to either one of two bridges that carry/carried traffic along the Ohio River between Ironton, Ohio and Russell, Kentucky in the United States. The original purple cantilever Ironton–Russell Bridge, opened in 1922 and closed in 2016, carried two lanes of traffic and a narrow sidewalk. The new white cable-stayed bridge, officially named the Oakley C. Collins Memorial Bridge, has two lanes of traffic without a dedicated sidewalk and opened on November 23, 2016.

Original bridge
The original purple cantilever Ironton–Russell Bridge opened in 1922.  It carried two lanes of traffic and a narrow sidewalk. 

The bridge was retrofitted in the 1970s with strengthening beams and plates.  Later inspection of the bridge revealed that these plates had been welded to the bridge using techniques that violated the bridge welding codes and reduced the fatigue strength of primary load members.  As a result of these findings, ODOT added reinforcements to some vertical members to improve structural redundancy.

The original span was still forced to close when temperatures approach –5 degrees Fahrenheit due to the brittle nature of the steel used. Continuous monitoring was routine during temperatures below freezing to check for any cracking in the substructure of the span. In addition, in May 2008, ODOT placed a width restriction on the bridge, banning all vehicles wider than 7 ft. 6 in. Emergency vehicles, non-commercial vehicles and non-profit buses (such as school buses) were exempt from the restriction. ODOT authorized both Ohio and Kentucky law enforcement agencies to enforce the restriction.

The original bridge remained open during construction of the new bridge, and was permanently closed at the completion of the dedication ceremony and parade. Demolition of the original structure began in December 2016 and was completed in June 2017.

Current bridge 
In 2000, the Ohio Department of Transportation (ODOT) released a report recommending the replacement of the then 78-year-old original span.  One of the replacements considered was a three-lane single-tower cable suspension bridge. The final design was chosen in January 2003, however, the high costs of constructing the bridge became apparent when costs for the new bridge came in at $110 million, well over the original estimated cost. The sharp rise was attributed to the dramatic increase in construction costs partially blamed on Hurricane Katrina, which increased the cost of concrete materials and items derived from petroleum products.

The bridge was redesigned as a two tower cable-stayed bridge, was reduced from three lanes to two and does not have a dedicated pedestrian walkway. Construction on the replacement span began in March 2012. Unlike the original bridge, which connects downtown Ironton with downtown Russell, the new bridge connects downtown Ironton directly with U.S. 23 and KY 244 within the city limits of Russell just south of downtown.

The new bridge opened on November 23, 2016 with a ceremony and parade through Ironton and Russell that included crossing both the new and original structures. As part of the ceremony, the new bridge was officially named for the late Oakley C. Collins, who represented Lawrence County in both the Ohio House of Representatives and the Ohio Senate.

The Russell approach got partly removed with some concrete demolished for the opening of the new Russell Viaduct in 2021.
