take I-25 south to the HWY 160 exit at Walsenburg. Then follow
HWY 160 west thru town for 6 . 5 miles until reaching the private

existing road owned by the landowner of property access . The
adjoining concrete plant operation uses it to access their plant
from HWY 160 . It is currently 25 feet wide and in the location
as shown on the map exhibits supplied with this application.
Periodic grading will be necessary to keep the road in its
