List of bridge constructions with the participation of Ralph Modjeski

Ralph Modjeski, 1931

The list of bridge constructions with the participation of Ralph Modjeski chronologically shows the bridge construction projects in which Ralph Modjeski (1861–1940) played a key role in his 50-year career. The basis is the biographical memoir of the National Academy of Sciences of WF Durand from the year 1944. Modjeski specialized initially in steel - truss bridges for railways , which he often as a combined rail and road bridges executed. As a leading expert in the field, he was responsible for the final construction of the Québec Bridge (1919), which is still the cantilever truss bridge with the world's largest main opening. Later he also designed several suspension bridges and arch bridges , including the Benjamin Franklin Bridge (1926) and the Ambassador Bridge (1931), which were then the longest suspension bridges in the world in terms of span . With a few exceptions, all bridge structures in which Modjeski was involved have almost been preserved in their original design and are still in operation (2018).

Ralph Modjeski was involved in the construction of more than 40 bridges in North America between 1885 and 1936

After completing his civil engineering studies at the École Nationale des Ponts et Chaussées in Paris in 1885, he worked under George S. Morison (1842-1903) in various positions on several bridges over the Missouri and Mississippi until 1892 . In 1893 he founded his own engineering office in Chicago and completed his first major construction project with the Government Bridge by 1896 . In 1902 he entered into a partnership with Alfred Noble (1844-1914) to build the Thebes Bridge , with whom he had already worked on the construction of the Frisco Bridge under Morison. At the beginning of the 20th century he employed Joseph B. Strauss (1870–1938) and Frank M. Masters (1883–1974), who later opened their own offices. He also expanded with offices in Pittsburgh and New York City . In the 1920s, he moved his headquarters to New York and the increase in orders led to the establishment of additional offices in Harrisburg , Philadelphia and New Orleans .

In the course of his career he made several employees of his engineering office partners, including from 1910 Walter E. Angier (1863-1928), from 1924 Frank M. Masters, from 1926 Clement E. Chase († 1933) and from 1933 Montgomery B. Case . The long-term collaboration with Masters lasted until Modjeski's career ended in the mid-1930s, and Masters took over the management of Modjeski & Masters between 1936 and 1937 after Case retired . The company continues to this day and continues to build and maintain bridges. In addition, he worked with Daniel E. Moran from 1925 to 1930 on the construction of the Mid-Hudson Bridge , and renowned bridge engineers and architects such as Leon Moisseiff , Othmar Ammann and Paul Philippe Cret were involved in advising and supporting many of Modjeski's over 40 bridges.

Chronology of the bridge construction

• Name: Name of the bridge according to the lemma in the German Wikipedia .
• Completion: year of completion of the bridge. The start of planning and construction, as well as Modjeski's commitment, can be several years earlier, information can be found in the main articles or individual evidence. If Modjeski was only subsequently involved in the construction project, this is indicated under Modjeski's role . In the case of conversions or extensions as well as later new buildings, the year of the original construction or the new building is given in brackets.
• Bridge type: construction form of the bridge . Some bridges are combinations of several different structures and movable bridge sections can also be integrated. As a rule, girder bridges for the driveways are not taken into account.
• Longest span: Longest span between the load-bearing elements such as abutments or bridge piers, with arched bridges the distance between the arch ends on the transoms .
• Total length: total length of the bridge or sections between the abutments , usually including the access roads.
• Client: Company or authority that Modjeski has engaged.
• Modjeski's role: How Modjeski was involved in the construction project. As chief engineer , he was the lead engineer responsible for the design and execution of the bridge. For collaborations where Modjeski's precise contribution is not known, only the company name of Modjeski's engineering office is given.
• Involved engineers / architects: Known engineers and architects involved in the construction project and their role or contribution.

The information on bridges that do not yet have an article in the German-language Wikipedia is referenced by the individual records listed under Name . If individual information in the table is not referenced via the main article, additional individual references are given at the relevant point.
