delivered the opinion of the Court.
This is a defendant’s appeal from a judgment entered upon a jury verdict awarding the plaintiff $20,000 in damages in a trip- and-fall case. The disрositive issue is whether the defendant, Medical Center Hospitals, t/a Norfolk General Hospital, was guilty of primary negligence in the сonstruction and maintenance of a sidewalk on its premises. Because we find the evidence insufficient to establish actionаble negligence, we need not consider the hospital’s contention that the plaintiff was guilty of contributory negligence.
On the afternoon of November 2, 1980, a bright, sunny day, the plaintiff, Mrs. Emily P. Sharpless, went to visit her mother who was a patient in the hospital. The entrance to thе hospital was served by a horseshoe-shaped sidewalk constructed of concrete slabs. Normally, Mrs. Sharpless used the left arm of the horseshoe. Because she had parked in a different place on this occasion, she used the right arm. As she apрroached the entrance, she “caught [her] toe” in an expansion joint separating two concrete slabs, “pitched fоrward completely”, and suffered extensive facial injuries.
William T. Powell, the plaintiffs father, examined the sidewalk shortly after the accident. Powell testified that the slab which caused the fall was higher than the adjacent slab. “I measured with my finger,” he said, and “[i]t graduates down . . . аbout a half-inch [at one point] and goes down about, I would say, an inch, inch and a quarter, maybe a little more.”
The plaintiff called A. Carl Schenck to testify as an expert in the design and construction of sidewalks. Schenck explained that concrete slabs must bе separated by an expansion joint to accommodate seasonal expansion and contraction. When properly constructed, a pliable material is inserted at a depth of half an inch *498 below the surface of the slabs and covered with a “filler”. He said that because there was no filler in the joint in question, there was a depression measuring half an inch. He found the sрace between the two slabs “open at one end approximately an inch and an eighth. And at the other end, approximately an inch and a half.” In his opinion, the joint “was defective when it was installed.” On cross-examination, he stated that he “did not look аt a difference in elevation between the two slabs” and had made no measurement of that dimension.
Bill Hollingsworth, the hospital’s safety and security officer, measured the difference in elevation with “an actual ruler” and “came up with a measurement of a hаlf inch” at “[t]he deepest part.” The 900-bed facility had a staff of 3000, and Hollingsworth estimated that “well over 2000” people use the sidewalk on a daily basis. He said that no accidents had been reported in the vicinity of this expansion joint during the five years he had worked for the hospital.
We have cautioned that a jury instruction expounding the duty owed by municipal corporations to sidewalk pedеstrians is not necessarily “appropriate to the owner-invitee context”.

v.
Sutherland,
*499 “[W]hen, as in this case, the defect is so slight that no careful or prudent man would reasonably anticipate any danger from its existence, but still an accident happens which could have been guarded against by the exercise of extraordinary care аnd foresight, the question of the defendant’s responsibility is one of law. . . . [Municipal corporations [have] the duty of guarding against such dangers as can or ought to be anticipated or foreseen in the exercise of reasonable prudence and care. But, when an accident happens by reason of some slight defect from which danger was not reasonably to be anticipatеd, and which according to common experience was not likely to happen, it is not chargeable with negligence.”

v.
Anderson,
A municipality is charged with the duty of maintaining its sidewalks in a safe condition, free from defects and obstructions dangerous to pedеstrians exercising ordinary care. A municipality is not, however, an insurer against all accidents which may occur on its sidewalks. A municipality need only maintain its sidewalks in a reasonably safe condition for travel in the ordinary modes. It is not expected, nor is it required, to keep the surface of its sidewalks perfectly level and even.
Not every defect in a sidewalk, even though it may have caused the injury sued for, is actionable. When the defect is so slight that reasonable men could not differ in concluding that it would not endanger travel in the ordinary modes by persons exercising ordinary care, the municipality is free of negligence as a matter of law and a trial court may not sustain a verdict holding the municipality liable.

Id.
at 792-93,
Viewing the evidence in the light most favorable to Mrs. Sharpless, and applying the principles in Sutherland and Anderson, we hold that the plaintiff failed to prove that the hospital was guilty of actionable negligence. Accordingly, we will reverse the judgment and enter final judgment for the hospital.
Reversed and final judgment.
