In The Works

LINKS TO WEBSITES OF ON-GOING CONSTRUCTION PROJECTS. SEE WHAT'S HAPPENING OUT THERE!

Hoover Dam Bypass
The joint venture contractor building the River Bridge, Obayashi Corporation and PSM Construction USA, Inc., is advancing construction of the 1,060 foot twin-rib concrete arch. Visit http://www.hooverdambypass.org/Whats_New.htm to explore this challenging project.

Iowa State University
As reported in ENR construction engineering students at Iowa State University, Ames, are getting a close-up look at distant project sites, and an enriched learning experience, through two-way portable jobsite video technology now being tested there. Visit http://www.fpm.iastate.edu/webcam/alumni/ to view construction of the new Alumni Center at ISU.

Dallas High Five Interchange
Visit the Zachry website and learn about the Dallas High Five Interchange they constructed. http://www.zachry.com/projects_TXDot.htm The accompanying PowerPoint presentation includes actual photographs of the Erector.

US 82 Greenville Bridge
The construction of a bridge across the Mississippi River is a grand spectacle. Visit www.greenvillebridge.com/ and checkout the multimedia show and the photo album.

Braddock Dam Segment Transport
The new Braddock Dam was constructed “In-the-Wet” from two large concrete segments that were fabricated at a casting facility in Leetsdale. This innovative construction method enabled these large floating structures to be launched into the Ohio River and then towed to Duquesne for outfitting. After outfitting they were towed to the Braddock project site on the Monongahela River, floated into place and set down upon a pre-constructed foundation system. Visit www.port.pittsburgh.pa.us/home/index.asp?page=70 to learn photos of the float. Use Google to find other information about this project.

Olmsted Locks and Dam
Olmsted Locks and Dam are located 17 miles above where the Ohio empties into the Mississippi River. The locks and Dam replaces Locks and Dams 52 and 53, the last wicket dams on the Ohio River, which were built in 1928-29. Visit the www.lrl.usace.army.mil/olmsted_specproj/ to view project photos.

Firth of Forth Rail Bridge
The Forth Railway Bridge is a remarkable cantilever structure that is still regarded as an engineering marvel and is recognized the world over. The structure, with its three massive cantilever towers each 104m (340 feet) high, was designed by Sir John Fowler and Sir Benjamin Baker, and constructed by Sir William Arrol. The work began in 1883, and after seven years, 55,000 tons of steel, the bridge opened in 1890. The Forth Railway Bridge was accomplished using a daring design. When completed, it was the longest span in the world. Today it is still the second longest of its kind. The Forth Bridges visitor center trust web site is at http://www.forthbridges.org.uk/. Visit that site first and then at http://www.brianseamens.pwp.blueyonder.co.uk/FORTH/index.htm you can find several pages that describe the construction of this historical bridge.
