About the Guide: The American Society of Civil Engineers (ASCE) celebrated its 150th  anniversary as a professional society in 2002.

The members past and present are proud of their contribution to the development of American society over these 150 years and showpiece some our most significant projects and personalities in the Mohawk and Hudson regions of New York State in the guide.

 

Many of the projects have been designated National Historic Civil Engineering Landmarks or State Historic Civil Engineering Landmarks by the ASCE. Some are on the National Register of Historic Places of the National Park Service. Our region was the birthplace of such historic civil engineering projects as:

· The Erie Canal (1825);

· The Mohawk and Hudson Railroad (1831);

· The Waterford (Union) Bridge over the Hudson River (1804);

· The Rensselaer and Saratoga Railroad Bridge at Green Island (1835) and more.

 

Civil Engineering Education got its start at the United States Military Academy, Rensselaer Polytechnic Institute and Union College in 1802, 1824 and 1845. The men who founded and ran these institutions are  among the giants of the early part of the 19th century.

 

Visit these bridges, buildings, reservoirs, roadways, railways, canals and gravesites and consider the way in which our country grew and prospered, partly through the efforts of civil engineers.

 

The guide offers a centerfold map with the general location of each of the landmarks in this guide. Further information on directions accompanies each entry. Take a day trip and visit these sites. If you are a teacher plan a field trip to see the sites and give your students an appreciation of the rich engineering history of our area.

A committee of the Mohawk and Hudson Section of ASCE prepared this guide with financial support for its publication by the Engineering firms and professional societies shown in the guide.

Text Box: Name: Rexford Aqueduct over Mohawk River, Enlarged Erie Canal 
Location: Mohawk River, between Rexford, Saratoga County, and Niskayuna, Schenectady County. (Adjacent to NY Rt. 146, Balltown Rd.)
History: The Upper Mohawk River (Rexford) Aqueduct was one of the major aqueducts of the enlarged Erie Canal, and replaced the original Erie Canal aqueduct (1823) at Rexford, near Alexander’s Mills. Along with the Crescent Aqueduct, it was one of two crossings over the river, designed for the original Erie Canal by Canvas White, C.E., to avoid a section of steep, rocky terrain on the river’s south bank. Both replacement aqueducts for the enlarged canal were designed by John B. Jervis. They were completed in 1842 and continued operation until the new State Barge Canal system opened in 1916. A major portion of  the Rexford Aqueduct was removed in 1965; nothing remains of the Crescent Aqueduct. Most of the stonework removed from the Rexford Aqueduct was stored for possible reconstruction in the future. The remains of the Rexford aqueduct are a NY State historical site. Two arches and three piers remain on each side of the Mohawk River. The masonry arches span approximately 45 feet and supported the canal tow path. The masonry piers, approximately 45 feet wide, supported the timber canal trunk. The enlarged Rexford aqueduct originally comprised 13 arches and 14 piers.

A Newsletter on the History and Heritage Of American Civil Engineering

The Committee on the History and Heritage of American Civil Engineering of ASCE is charged with the task of originating and conducting programs relating to the history and heritage of the profession and promoting local, national and international programs to create public and member understanding of civil engineering. Many members are aware of the Historic Civil Engineering Landmarks Program and many sections have nominated projects for this designation.

 

This newsletter is to keep the membership informed on what is happening in the area of history and heritage around the country and the world.
