state line The road from
Beryl Junction west to
Modena became a state highway in 1918, and in 1927 the legislature extended it west to the
Nevada state line (at
SR 25) and numbered it as part of
SR-18. A connection from SR-18 at Beryl Junction east to
SR-1 (
US-91, now
SR-130) in
Cedar City was added in 1931 as State Route 56, and in 1935 that route absorbed the segment of SR-18 to the state line. SR-56 originally crossed the mountains between Cedar City and Beryl Junction via
Desert Mound, following the present Desert Mound Road. Two branches from SR-56 to
Iron Mountain were added in 1935:
State Route 120 directly south from about the midpoint, and
State Route 198 from near the Cedar City end southwest via Iron Mountain to the
Dixie National Forest in the direction of
Pinto. Both routes were deleted in 1945, and SR-56 was realigned via Iron Mountain, with the portion of SR-198 east of that settlement becoming part of the new route. Both were given back to the county in 1969. ==Major intersections==
