 According to a November 2004 survey published by Better
Roads Magazine, 150,000 of the United State's 594,000 bridges
are substandard. Most of the structures are short span bridges and fall
within the 20’ to 120’ span range. Virtually every one of
them could be replaced with durable, sustainable, economical
steel.
Bridge engineers are always concerned with finding the most
cost-effective bridge solutions. However, the time and funding
available for comparing alternatives often is limited, particularly for
short-span bridges. To address the time and funding needs of bridge
owners and designers, AISI has developed short-span bridge design aids,
guidelines, and educational seminars to help them choose the best
material for the job.

Short Span Steel Bridge
Alliance
The Short Span Steel Bridge Alliance is a group of
bridge and culvert industry leaders, including manufacturers,
fabricators and representatives of related associations and government
organizations who have joined together to increase awareness of the
unique benefits, cost-competitiveness and safety facts related to the
use of short span steel bridges in installations up to 140 feet in
length. Alliance members include: the American Iron and Steel Institute,
Big R Manufacturing, the Federal Highway Administration, National
Corrugated Steel Pipe Association, National Steel Bridge Alliance,
Nucor-Yamato Steel, Roscoe Bridge, U.S. Bridge and Wheeler Lumber
LLC.
Short Span Steel Bridges Offer Significant Benefits
Newly developed steel grades with higher yield strength, better
toughness and improved weldability offer significant benefits in weight
savings and fabrication cost reduction in the design of short span
beidges. Steel offers solutions for all types of crossings. Short span
steel bridges can be built quickly, using local crews and many can be
designed using prefabricated components which are simple to install and
offer considerable cost savings. Fast. Flexible. Simple. Cost effective.
That¹s the steel advantage.

Steel Bridge Construction: Myths &
Realities
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.

Box Elder Creek Case Study
In November of 2007, Modern Steel Construction Magazine
presented a case study on the Box Elder Creek Bridge in Watkins,
Colorado -- a wonderful spotlight on an award-winning short span steel
bridge!
