ISTEA includes provisions for which two programs?

• A. National Scenic Byways Program and Transportation Enhancements
• B. Clean Air Act and Clean Water Act
• C. Historic Preservation Act and Endangered Species Act
• D. National Park Service and Bureau of Land Management

Answer: (D)

ISTEA expanded federal transportation policy to include environmental, scenic, and historic values, and it created two programs to carry that out. The two programs are the National Scenic Byways Program, which designates and funds improvements on nationally significant scenic and historic roads, and Transportation Enhancements, a broad funding category for projects like bicycle and pedestrian facilities, landscaping and historic preservation, scenic beautification, wildlife corridors, and trails along highway corridors. These provisions were specifically established by ISTEA to broaden what federal transportation funding can support.

The other options point to existing environmental laws or agencies, not programs created by ISTEA. Clean Air Act and Clean Water Act are earlier environmental statutes; Historic Preservation Act and Endangered Species Act are separate protections; National Park Service and Bureau of Land Management are agencies, not ISTEA programs.
