Business loops signed from Interstate 20 in Texas have both ends signed from the mainline. This example shows Business Loop I-20P in Merkel. Exit 270 is the eastern end of the loop, and Exit 267 is the western end of the loop. While Arizona and Idaho generally follow the Texas approach to signing business loops at both ends, other states such as Wyoming, Montana and South Dakota only sign the first interchange with Business Loop shields.
