List of bridge constructions with the participation of George S. Morison

The list of bridge constructions with the participation of George S. Morison chronologically shows the bridge construction projects in which George S. Morison (1842–1903) was significantly involved in his approximately 35-year career. The list is based on the papers by Clayton B. Fraser (1986) and Frank Griggs, Jr. (2008). Like the biographical memorandum of the National Academy of Sciences from 1905, the latter mentions two further bridges in Ainsworth ( Washington ) and Belknap ( Montana ) between 1883 and 1884, which are not included in Fraser's overview and were not included in the list due to insufficient sources .

Morison designed over 20 bridges in the United States, erected between 1875 and 1907

Originally trained as a lawyer , Morison began a career as a civil engineer in 1867 at the age of 23 . Without formal training in the field, he gained his first experience under Octave Chanute (1832-1910) and carried out intensive self-study, which he maintained throughout his entire professional career. Morison devoted himself primarily to bridge building at the time of the expanding railroad companies in North America at the end of the 19th century and became one of the leading experts in this field. He realized over twenty large railroad bridges , including over the Missouri , Mississippi and Ohio Rivers . During his career, Morison worked alongside Octave Chanute with many well-known civil engineers such as Charles Conrad Schneider (1843–1916), Alfred Noble (1844–1916) and Ralph Modjeski (1861–1940), with the latter surpassing his teacher and later Morison became one of the most important bridge engineers in the USA. Between 1887 and 1889 Morison also entered into a partnership with Elmer Lawrence Corthell (1840–1916), who together as Morison & Corthell built several bridges from Florida to Oregon .

Bridge constructions

• 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 the commitment of Morison can be several years earlier, information can be found in the main articles or individual evidence. 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 Morison has engaged.
• Role of Morison: How Morison will be involved in the construction project. As chief engineer , he was the lead engineer responsible for the design and execution of the bridge.
• 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 are 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.
