The American Bridges, St.Petersburg
The wooden bridges of the same design as now were constructed over the period 1840-1850 during the construction of the Nikolayevskaya Railway. The main construction works were supervised by the prominent American railroad engineer George W. Whistler to a design by William Howe, an American bridge builder and inventor.
The wooden bridge over the Obvodny Canal was originally constructed by George W. Whistler using the Howe-Zhuravsky system. It served its purpose effectively for approximately three decades. However, in 1869, a decision was made to replace it with new metal spans. The task of designing the new bridge was entrusted to Nikolai Belelubsky, a renowned Russian civil engineer who had successfully constructed numerous railroad bridges throughout the Russian Empire. Belelubsky showcased his exceptional talent and expertise as both a scientist and a practitioner. He managed to organize and categorize existing steel bridge designs, subsequently developing a set of standardized span structures.
Although modifications were made to the design of the wooden bridge, the resulting metal structure bore a striking resemblance to the previous truss system known as the Howe-Zhuravsky. Just like its wooden predecessor, the newly constructed steel bridge also featured a double-track configuration.
