Margarita to Route 41 near Creston
Post 1964 Signage History
In 1963, Route 229 was defined as the route “Route 58 near Santa
to Route 41 near Creston”.
Pre 1964 Signage History
This route was LRN 137, defined in 1933. It was unsigned before 1964. The
portion from Creston to 3 mi S of Creston may have been part of US 466 in
This route is signed between Route 58 and Route 41. It is supposedly
signed (as of 2004) at the junction with Route 58. The road itself
is only one lane wide from Route 58 north to a mile southwest of Rocky
Road, at which point it becomes a two-lane route all the way through
and to its terminus at Route 41. (On Route 41, there are signs pointing to
Route 229 at that junction as well). The route itself doesn't seem to have
trailblazers but does have mileposts (a similar situation to Route 221 in
which is signed at the junctions but not on the route itself).
