Stone-Walling
in Arkansas
by Laurin R. Lineman
The Arkansas State Highway and Department of Transportation (AHDT)
invited the Eastern Federal Lands Highway Division (EFLHD) of the
Federal Highway Administration (FHWA) to assist in the reconstruction
of a portion of Forest Highway 65 between Cass and Oark. One of the
goals was to maintain the unique physical relationship of the
sheer bluffs [along the Mulberry River], the natural scenery of the
Mulberry Valley, and the scenic experience this provides for viewing
from the river and road. To satisfy this goals, EFLHD designed
and constructed an aesthetic, natural stone retaining wall.

Combines Best Practices for an Innovative Interstate Rehabilitation
Program
by Dan Flowers and Sandra L. Otto
AHDT is rehabilitating 380 miles (612 kilometers) or 60 percent
of its interstate highways in five years. The department has put together
numerous best practices — in financing, project management, construction,
and communications — that together create a compelling model
for tackling a project of this scope.
Small
Investment, Dramatic Dividends — Saving Lives in Blood
Alley
by Dave Davis
The Oregon Department of Transportation, three northwest Oregon
counties, a community traffic safety committee, and a Native American
tribe worked together to improve a dangerous corridor, dubbed Blood
Alley by local residents, and as a result, traffic fatalities
along the corridor have dropped dramatically over the past three years.
National
Review of the Highway Safety Improvement Program
by Kenneth Epstein, Gary Corino, and Donald Neumann
Last year, a national review was conducted of the highway improvement
programs in six states. The primary purpose of this review was to
document the best, unique safety practices of each state.
Weather:
A Research Agenda for Surface Transportation Operations
by Gary G. Nelson and Rudy Persaud
Weather crosscuts almost every goal, use, and operation of highways,
and yet, meteorology, from a transportation perspective, is focused
mostly on the flight operations. To make weather issues an important
part of highway programs, people who manage highway operations must
seek new techniques and intelligent transportation systems that complement
the amazing system of weather-information collection, analysis, and
forecasting that exists in the United States.

by the National Partnership for Highway Quality
The National Partnership for Highway Quality recognized 26 states
for their outstanding highway projects. The award winners were
selected on the basis of the following criteria: quality process and
results, customer focus, teamwork, innovation and value, and
long-term improvement.
FHWA
Model Predicts Noise Impacts
by Cynthia Lee and Judith Rochat
The FHWA Traffic Noise Model (TNM) is a new state-of-the-art computerized
model used to predict noise levels in the vicinity of highways. TNM
uses advanced acoustics and computer technology to improve the accuracy
and ease of modeling highway traffic noise, including the design of
efficient, cost-effective highway noise barriers.
Synergy
in Action: FHWAs Transportation Pooled-Fund Program
by Brett Joseph
The Transportation Pooled-Fund Program enables various public and private
entities to pool their resources to jointly fund research
aimed at solving a wide variety of transportation-related problems.
FHWAs central role is to administer the program and to act as
a broker of the funds obligated to pooled-fund projects.
