John Job Crew Bradfield was born in Sandgate, Queensland on the 26 December 1867. He was educated at Ipswich State School, Ipswich Grammar School and the University of Sydney, where he graduated as a Bachelor of Engineering in 1889. In 1891 he married Edith Jenkins. They had six children.

In 1891 Bradfield joined the New South Wales Department of Public Works as a temporary draftsman, becoming permanent in 1895. He was involved in such major projects as the Cataract Dam and Burrunjuck Dam. In 1909 he became assistant engineer and in 1913 he was appointed chief engineer for metropolitan railway construction. He went overseas in 1914 to study railway construction and in the next few years wrote many papers advocating the electrification of suburban railways. Work commenced on the underground railway in 1923 and the first stations were opened in 1926.

It will be the effort of the writer in the following pages to point out the peculiarities of material and construction involved in the designing and building of “Iron Highway Bridges,” in the hope that a dissemination of their scientific principles in a popular form, will bear fruit in a more thorough appreciation of a noble art, and in elevating the standard of requirements of this very important class of public works. The subject has been divided into two parts, each complete in itself; the one general and descriptive, and the other analytical. The former is peculiarly intended to present to public committees entrusted with the letting of bridge contracts such information as they ought to possess, while the latter is offered as an aid to engineers not experts in this branch of the profession, and yet who are often called upon to act as inspectors.

A gift of John F. Harbeson, the archive consists of Cret's student and professional work and is displayed on approximately four hundred and seventy-six sheets containing one or more drawings, photos, or prints per sheet. The archival holdings may be broadly divided into eighty-eight sheets of student work at the Ecole des Beaux Arts in Lyon and Paris, fifty-three student and professional watercolors, thirteen sheets of bookplates, seals, medals and title pages, fifty-six sheets of competitions (thirty-two of various university designs), nine sheets of commercial work, one hundred and two of memorials, twenty-two sheets of government buildings, twelve residential designs, twenty-one sheets of bridge designs, five sheets of watercolors and ink sketches by Col. Oscar Lahalle (Cret's father-in-law), and one hundred and eleven sheets of varied design work.

Begun in 1867 and completed in 1874, the Eads Bridge was named after its designer, James Buchanan Eads. It was the first bridge to span the Mississippi at St. Louis, the first bridge to make significant of steel, and one of the first bridges in the U.S. to make use of pneumatic caissons (the caissons sunk for the bridge are still among the deepest ever). It was also the first bridge to be built entirely using cantilever construction methods, avoiding the need for falsework, and the first bridge designed so that any part could be removed for repair or replacement. The bridge is now a National Historic Landmark.

Welcome to the online edition of Bridging the Bay: Bridging the Campus.

...At a time when the Bay Area’s bridges are being analyzed and new structures are being planned, it is important to recognize the diversity and depth of the research collections that exist on the Berkeley campus. The exhibit includes books, documents, architectural drawings and renderings, blueprints, artifacts, maps, and photographs. The bridges documented include the Golden Gate Bridge, the San Francisco-Oakland Bay Bridge, the Carquinez Bridge, the Richmond-San Rafael Bridge, the Antioch Bridge, and the Dumbarton Bridge. The exhibit also contains documents detailing Bay Area bridge projects that were seriously considered, but were never built.

Drury Blakeley Alexander (1924-), architectural educator, served as professor at the University of Texas School of Architecture and continues to serve the city through the Historic Landmarks Commission and the University as a champion of the preservation of the University's historic buildings, resident historian, and special friend to the Architecture and Planning Library. Creative works, correspondence, memoirs, printed material, minutes, maps, images, photographs, student work, slides, and artifacts, (1887-1995) created or collected by Drury Blakely Alexander, evidence his career in education and interests in architectural history and preservation.

This an historic occasion. Today we are gathered here to dedicate a famous pioneer structure -- the oldest cable suspension highway bridge in the world -- as a national monument. Because this span has played a dramatic and significant role in the development of bridge engineering, and because its outstanding record of more than a century of distinguished service is interwoven with the unfolding panorama of American history, it is altogether fitting and proper that the shrine to thrill and inspire future generations.

When this great structure -- the first bridge over the Ohio River -- was completed in 1849, it was truly notable achievement. Its span of 1,010 feet was by far the longest in the world, the first time human courage and resourcefulness had achieved a span exceeding one-thousand feet.

ELLET, Charles, civil engineer, was born at Penn's Manor, Bucks co., Penn., Jan. 1, 1810, son of Charles and Mary (Israel) Ellet, and grandson of Charles and Hannah (Carpenter) Ellet. His father, a farmer, was a member of a well-known Quaker family and his mother, daughter of Israel Israel of Philadelphia was one of the most remarkable women of her time, being alluded to by a Philadelphia journal as the "American Cornelia." The son was brought up on his father's farm and attended school at Bristol, Pa. From his earliest years he had shown an unusual talent and fondness for mathematics and at the age of sixteen had far outgrown the scope of the school's mathematical curriculum. After a course of study at the Ecole Polytechnique, Paris, France, he secured employment on various engineering works becoming first assistant and soon afterward chief engineer of the James river and Kanawha canal. His attention at this time was devoted chiefly to the study of methods of inland communication, more particularly suspension bridges, and in 1841-42, he constructed the wire suspension bridge across the Shuylkill river at Fairmont, the first of its kind in America.

On June 12, 1806, John A. Roebling, civil engineer and designer of the Brooklyn Bridge, was born in Muehlhausen, Prussia. The Brooklyn Bridge, Roebling's greatest achievement, spans the East River to connect Manhattan with Brooklyn. For nearly a decade after its completion, the bridge, with a main span of 1595 feet, was the longest suspension bridge in the world. Steel wire cable, invented and manufactured by Roebling, made the structure possible.

When the Brooklyn Bridge was opened you had to pay three cents to cross it until it was paid for. When they opened the bridge everybody went to see it..It took them 14 years to build the Brooklyn bridge.
