More CSS Information From The Federal Highways
The federal government, through the Federal Highway
Administration (FHWA), is encouraging states to adopt
the CSS approach to transportation planning and design.
The FHWA implemented, in 1997, a pilot project for
CSS, using CSS techniques on transportation projects in
five states across the country: Kentucky, Utah,
Minnesota, Maryland and Connecticut. (Please visit the
FHWA's CSS website for further details.) All of
these states have since adopted the CSS approach in
their transportation decision-making.
Currently, 43 out of the 50 states have some sort of
CSS policy or program
The FHWA has published a guidebook for using the CSS
approach and techniques. View the Federal Highway
Administration's explanation and definition of CSS, "Flexibility
in Highway Design."
