Impacts to CTTM result from travel designations that open, limit, or close areas to travel. Additional impacts result from management that affects the number or quality of roads and trails or management that affects opportunities for access on- or off-road using motorized, mechanized, equestrian, or foot travel.

Alternative C would result in the most new road and trail development, primarily due to the larger acreage open to cross-country motorized travel, followed by alternatives D, B, and A. Under alternatives B and D, the BLM specifically establishes the most new trails and roads for motorized, mechanized, and primitive recreational uses, but does not manage as many acres as open to cross-country motorized travel as under Alternative C.

ROW exclusion areas would prevent the construction of new roads authorized through a ROW permit that could be used for motorized vehicle use. ROW exclusion areas would restrict the development of new travel routes most under Alternative B, followed by alternatives A, D, and C.

Alternative B includes the most limitations on and closures to motorized and mechanized vehicle use for resource protection. Therefore, this alternative would cause the greatest adverse impacts to access opportunities for motorized vehicle use, followed by alternatives D, A, and C. Alternative B limits the most acreage to designated roads and trails in the Planning Area (2,054,228 acres), followed by alternatives D (1,055,257 acres), C (951,992 acres), and A (787,626 acres). The area limited to existing roads and trails is greatest under Alternative A (2,332,355 acres) followed by C (2,144,623 acres), D (2,028,620 acres), and B (931,803 acres). Alternative B closes the greatest acreage to motorized vehicle use (136,474 acres), followed by alternatives D, A, and B, which close 60,681, 59,192, and 10,636 acres, respectively. Due to the size of the Planning Area and the limited number of new projected roads, restrictions on motorized and/or mechanized travel on existing routes may have a greater effect on travel and transportation management than the miles or location of new road development.

Overall, Alternative C would cause the fewest adverse impacts (and the most benefits) to CTTM, followed by alternatives A, D, and B.
