Bridges
The Federal Highway Administration estimates that nearly one-third of
America’s 594,000 bridges are either structurally deficient or
functionally obsolete. Steel bridges offer viable design
solutions for bridge owners
because they are durable, cost-effective, and offer ease of maintenance
and construction. For more advantages to steel bridges, click

Special Announcement:
Steel Bridge Construction: Myths & Realities Released!
January 17, 2008
An updated fact-based publication that addresses a
wide range of topics about steel bridges is now available through a
joint effort between the American Iron and Steel Institute (AISI),
American Institute of Steel Construction (AISC) and the National Steel
Bridge Alliance (NSBA). For example, did you know that modular
prefabricated short-span steel bridges can be permanent structures? Or
that bridge joints are not a prerequisite for steel bridges? Or that
advanced high-performance, EPA-approved steel bridge coatings can last
more than 25 years? ed fact-based publication that addresses a wide
range of topics about
These topics and others are highlighted in the free
publication titled Steel Bridge Construction: Myths and
Realities. This 25-page document compiles and corrects top myths and
misperceptions about the viability of steel in bridge design and
construction for a wide range of bridge types.

NEW! "Steel Has the Solution" Fact Sheet
A new fact sheet that illustrates the numerous ways that steel can be
incorporated into a cost-effective short span bridge design is now
available. To download your copy of the "Steel Has The Solution"

Federal Highway Administration (FHWA) Offers Grants to Spur
Innovation
Highways
for LIFE Technology Partnerships Program seeks prototypes to improve
roads
The Federal Highway
Administration (FHWA) is seeking applications and will award multiple
grants in support of the Highways for LIFE Technology Partnership
Program. FHWA anticipates opening the solicitation for the program
on or about March 2, 2007, with a closing date on or about April 15,
2007. The program anticipates as many as 12 awards at the $200,000
funding level and 3 awards at the $500,000 funding level.

High-Performance Steel: Research to Practice: by
William Wright
A new grade of high-performance structural steel, HPS-485W, is now
commercially available for highway bridge construction. This is the
first product developed under a highly successful cooperative research
program between the Federal Highway Administration (FHWA), the U.S.
Navy, and the American Iron and Steel Institute.
Emerging Construction Technologies: High
Performance Steel
High strength steels have been available for years, but their use
required more welding control and fabrication processes than
conventional strength steels. For this reason few bridge owners have
been willing to risk potential problems in fabrication, eventhough the
design could be more efficient with higher strength steel.
Team Honored for Developing High Performance
Steel For Bridges By Mary Zoccola
A team consisting of members from the Carderock Division, the American
Iron and Steel Institute (AISI) and the Federal Highway Administration
(FHWA) received the 1997 Civil Engineering Research Foundation (CERF)
Charles Pankow Award for Innovation.
Focus on High-Performance
While there have been many advances in steel-making technology over the
last 20 yrs., today structural steels in the United States are not very
different from those used 20 years ago.

HPS Success
Integrating high-performance 70 ksi steel (HPS) with traditional 50 ksi
steel yielded a design that cost 10% less than the lowest concrete
bid.
