Not any longer. There was an old statute which was enacted in 1889 which provided for the automatic vacation of county roads which remained unopened for five years after being platted or dedicated. This statute was amended in 1909 so that it no longer applied to platted streets and alleys. Therefore, this statute only applied to roads which were county roads and remained unopened for five years after dedication between 1889 and 1909.
Obviously, this is not going to apply in very many situations but occasionally reference is still made to the provision and it is found to be applicable.
