More CSS Information From The Federal Highways Administration

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, 26 states either have adopted a CSS policy or are developing one. (See the map below.) The FHWA has set a goal of all states adopting the CSS approach by 2007.

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."

Case Studies

The following is a selection of case studies that illustrate application of the principles and thought process behind CSD/CSS. The case studies are geographically diverse. They illustrate a wide range of project contexts, from rural roads to urban streets. They demonstrate that one can be context sensitive when dealing with a freeway, an arterial, or a local road.
