The Transportation Enhancement Program was established for transportation enhancement activities through the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). The Transportation Equity Act for the 21st Century (TEA-21)of 1998 continued this program through the year 2003. Ten percent of the Surface Transportation Fund is set aside for these activities. In TEA-21, the term transportation enhancement activities means:
Provision of facilities for pedestrians and bicycles.
Provision of safety and educational activities for pedestrians and bicyclists.
Acquisition of scenic easements and scenic or historic sites.
Scenic or historic highway programs (including the provision of tourist and welcome center facilities).
Landscaping and other scenic beautification.
Historic preservation.
Rehabilitation and operation of historic transportation buildings, structures, or facilities (including historic railroad facilities and canals).
Preservation of abandoned railway corridors (including the conversion and use of it for pedestrian or bicycle trails).
Control and removal of outdoor advertising.
Archaeological planning and research.
Environmental mitigation to address water pollution due to highway runoff or reduce vehicle-caused wildlife mortality while maintaining habitat connectivity.
Establishment of transportation museums.
The Federal Highway Administration (FHWA) has directed that this list is all inclusive. That is, the ten percent set aside can only be spent on these kinds of activities. No other activities or programs can be funded with this money.
