Plaintiffs appealed certain special assessments levied by defendant to the district court pursuant to Minn. St. 429.081. ^[1] Before a final determination of that appeal, plaintiffs moved the court to set aside the assessments summarily on the ground that defendant had not complied with the time requirements in Minn. St. 429.041, subd. 1, for giving notice of bids when it awarded the contracts for the improvements which resulted in assessment. The court entered an order denying the motion and plaintiffs have appealed from that order. We dismiss the appeal because that order is nonappealable. ^[2]

The order in question is an intermediate one. It has not prevented plaintiffs from proceeding to trial or presenting other objections to the assessments and obtaining a final order of the district court disposing of their entire appeal. In such a case, we will not allow encroachment upon our appellate jurisdiction by[*161] encouraging a separate appeal on each potentially dispositive issue the parties choose to raise.

Plaintiffs argue that their appeal is proper because it is taken from an order involving a part of the merits of their action within the meaning of Rule 103.08(d), Rules of Civil Appellate Procedure. That provision was not intended to permit routine appeals from denials of pretrial attempts by plaintiffs to get trial courts to resolve cases in their favor. While this court has not yet ruled on the specific order here presented, our holdings on analogous types of orders are instructive. We have held that denials of motions to dismiss, ^[3] to strike all or part of a pleading, ^[4] and for summary judgment ^[5] áre generally nonappealable. The case most closely on point is In re Appeal of Williams, 263 Minn. 581, 116 N. W. 2d 589 (1962). The action below was an appeal from certain orders of a county superintendent of schools. Appellants’ motion for summary judgment had been denied, and they appealed to this court. We held that the order appealed from was not final and dismissed the appeal without prejudice to the[*162] rights of appellants to seek review of the issues involved after a final determination by the district court.

An appeal in this type of proceeding is best taken from the final order of the district court affecting a substantial right in a special proceeding in accordance with Rule 103.03(h), Rules of Civil Appellate Procedure. Since the district court’s decision that bid notice was sufficient will not in any way hamper or prejudice proper consideration of other issues in plaintiffs’ action, it is in the interest of judicial economy to dispose of all issues in a single appeal to this court following termination of the proceedings below. Cunningham, Appealable Orders in Minnesota, 37 Minn. L. Rev. 309, 323 (1953). ^[6]

Although plaintiffs maintain that our exercise of jurisdiction in this case would dispose of the action in their favor and save further efforts by all concerned, an examination of the merits of plaintiffs’ argument belies their contention. Plaintiffs argue that bid notice was defective because publication of notice was not made “at least once in a newspaper or trade paper published in a city of the first class no less than three weeks before the last day for submission of bids” as required by Minn. St. 429.041, subd. 1. First publication was made on May 18 and May 25 for two different types of improvements, and the last days for submission of bids were June 8 and June 15 respectively. Under Minn. St. 645.15, ^[7] our time-computation statute, the day of first publication is excluded and the day of final submission included, and notice is sufficient for both types of improvements. We have very recently applied that statute in a similar time-[*163] computation case. Township Board of Lake Valley v. Lewis, 305 Minn. 488, 234 N. W. 2d 815 (1975). We have previously indicated our intention to apply that statute uniformly to all questions of time computation unless the terms of a statute affirmatively specify another method of computation. Nelson v. Sand-kamp, 227 Minn. 177, 181, 34 N. W. 2d 640, 643 (1948). Minn. St. 429.041 specifies no other method, and the bid notices are therefore sufficient.

Appeal dismissed.
