v.
BOARD OF COUNTY ROAD COMMISSIONERS OF MONTMORENCY COUNTY
Docket No. 15074.
Michigan Court of Appeals.
Decided March 26, 1974.
Higgs & Higgs, for plaintiff.
Fred E. Foster, for defendant.
Before: R.B. BURNS, P.J., and ALLEN and O'HARA,[*] JJ.
R.B. BURNS, P.J.
Plaintiff owns a large plat of land through which an old logging trail runs. Defendant contends that the trail should be considered a public road and part of the county highway system. At the first trial, the trial court found in favor of defendant, and entered a judgment giving defendant power to maintain the trail at its, then, present width and condition. However, after defendant became aware of the terms of the judgment, but before the judgment was entered and without the trial court's knowledge or approval, some of defendant's heavy equipment and employees were sent to make improvements on the *260 trail. They chopped down trees, cleared away brush, and crowned and widened the trail.
Plaintiff brought these actions to the attention of the court in a motion for a new trial. A partial new trial was granted pursuant to GCR 1963, 527. It was determined that before these actions were performed, the trail consisted of two ruts separated by a mound of turf. Only one car could use it at a time and it was impossible to determine where the supposed right-of-way ran. The trail was impassable during parts of the year. It was in no condition to be maintained. The improvements transformed the trail into a dirt road that could be maintained throughout the year, that had a definable right-of-way, and that was wide enough to permit cars to pass each other on meeting. Upon completion of the partial new trial, the trial court entered a new judgment which completely reversed its previous judgment and held that the trail was plaintiff's private property. Defendant appeals claiming that the trial court's second judgment is against the weight of the evidence.
The unauthorized eleventh-hour tactics of the defendant could reasonably be viewed as improper conduct or new evidence sufficient to justify the granting of a partial new trial under either GCR 1963, 527.1(2) or GCR 1963, 527.1(6). See also Benmark v Steffen, 9 Mich App 416; 157 NW2d 468 (1968).
The trail was never formally dedicated to public use. The question, then, is whether the trail has become a public road through public user. To be a public highway by user there must be a defined line or right-of-way for the road; the road must be used and worked upon by public authorities; it must be traveled over and used by the public for ten consecutive years without interruption; and *261 such possession must be open, notorious, and exclusive so as to provide the owner proper notice of the challenge to his proprietary rights. Alton v Meeuwenberg, 108 Mich 629; 66 NW 571 (1896), and Missaukee Lakes Land Co v Missaukee County Road Commission, 333 Mich 372; 53 NW2d 297 (1952).
Defendant's own witnesses testified the trail had no definable right-of-way and it was impassable to two-car traffic prior to defendant's roadwork. It was impossible to maintain the road before the improvements were made.
There was ample evidence to sustain the findings of the trial judge.
Affirmed. No costs, a public question.
All concurred.
