Preface

This Sourcebook presents guidelines for improving the appearance
of short- to medium-span bridges (those with spans up to about 300
feet). These structures constitute the great majority of bridges
and are often referred to as "workhorse" bridges. The intended
audience includes all of those engaged in advancing transportation
projects: engineers, administrators, planners, environmentalists,
and the general public. The goal is to encourage a common
understanding of and terminology for bridge aesthetics that will
encourage interaction among these individuals and result in more
attractive and context sensitive bridges throughout the United
States.

The Sourcebook begins by explaining why it is necessary to
consider bridge aesthetics. It then provides practical,
easy-to-apply ideas for design engineers and other professionals to
use in developing elegant designs for the typical bridges on which
they work every day.

This Sourcebook has been prepared by the Subcommittee on Bridge
Aesthetics (AFF10(2)) of the Transportation Research Board (TRB).
Full credits may be found at the end of the Sourcebook. The
Sourcebook was approved by the subcommittee's parent committee,
TRB's General Structures Committee (AFF10), at the January 2010
meeting of TRB.

The Sourcebook was presented for comment to the Subcommittee on
Bridges and Structures (SCOBS) of the American Association of State
Highway and Transportation Officials (AASHTO) at its May 2008
meeting. No comments were received from SCOBS members, so the
Sourcebook was placed on the agenda of the May 2010 meeting for
approval by SCOBS. Prior to the meeting, during preliminary
consideration of the Sourcebook by the T-9 committee of SCOBS, one
SCOBS member presented comments. This final version of this
Sourcebook reflects responses to those comments. SCOBS approved it
for AASHTO publication by electronic ballot in September 2010.
