Colby Avery, Engineer, Dies
Supervised Moving of Rock River Bridge
Colby M. Avery, well-known engineer who while superintendent of the Rockford street department planned and executed the moving of a bridge spanning Rock river without dismantling the structure, died Sunday in Aurora. He was 84 years old.
Funeral services will be conducted tomorrow afternoon in the Healy chapel, Aurora with burial in Greenwood cemetery, Rockford.
Mr. Avery resided in Rockford from about 1880 to 1900 and it was during this time that he succeeded in moving a bridge from State street without taking it apart.
Other engineers said the feat was impossible, but Mr. Avery filled barges with water and sunk them under the State street span. When they were in place, the barges were pumped out and when they rose the bridge was lifted off its piers.
The structure was floated down to Chestnut street and the barges resunk, allowing the bridge to settle on it's new foundations. It was eventually by the present concrete structure.
In addition to serving as superintendent of streets, Mr. Avery had been a bridge engineer for the F.C. Austin company, a salesman and engineer for Chisholm, Boyd and White Manufacturing company and an engineer for the Stephens and Adamson company in Aurora until he retired 10 years ago.
He was born Jan. 18, 1859 in Belvidere and was married on May 27, 1880 in Rockford to Emma Belle Shedd, who preceded him in death Jan. 30, 1898.
On May 2, 1899, he married Ellen Decker of Rockford, who died Dec. 7, 1940.
Surviving are two sons, Wallace H. Avery, East Orange, N.J., and Frank B. Avery, Aurora; two grand-sons, Frank B. Avery Jr., Elmhurst, and Staff Sgt. Hugh Mitchell Avery with the army air forces at Seattle, Wash. A great-grandson, Donald G. Avery, also survive.
Mr. Avery was a member of Wesley Methodist church in Aurora.
