{¶ 1} Appellant Herbert Haynes was injured when an eighteen-wheel dump truck tractor-trailer rig he was driving left the road and collided with a tree. He and his wife initiated this action by filing a complaint alleging that he had been injured due to the negligence of the appellee city of Franklin. Haynes asserted that his injuries were “a direct and proximate result of the City of Franklin’s violation of Revised Code Section 2744.02” in that a roadway upon which he was traveling on November 3, 1994, was not free of nuisance.
{¶ 2} Haynes alleged that the city had contracted with a road paving contractor to repair and resurface Trenton-Franklin Road in Franklin during the summer of 1994, and that the addition of new paving materials resulted in edge drop-offs of up to seven inches from the traversed surface to the adjacent berm. He asserted that he was driving through the construction area when the right front tire of his rig went off the right edge of the roadway. In attempting to steer to the left to return all wheels of the truck to the paved surface, Haynes lost control of his vehicle, which then crossed the road and struck a tree on the opposite side. Haynes further alleged that the city had failed to erect adequate signage and barricades through the repaved area. The city answered and asserted the defense of political subdivision immunity pursuant to R.C. Chapter 2744.
{¶ 3} During discovery, the city represented that it had determined that the city itself, rather than the contractor, would finish the construction project by constructing berms adjacent to the repaved roadway. It further admitted that the berming phase of the project had begun before the Haynes accident, although berming had not yet been done in the area where Haynes’s accident occurred.
*345{¶ 4} The city moved for summary judgment in its favor, which the trial court initially denied. However, the court reconsidered the city’s motion following the decision of the Twelfth District Court of Appeals in Stevens v. Ackman (Dec. 20, 1999), Butler App. No. CA99-03-053, 1999 WL 1255806,1 and entered judgment for the city based on a finding of immunity.
{¶ 5} The court of appeals, in a split decision, affirmed, concluding that an “edge drop between the paved road and the berm does not amount to a nuisance as that term has been defined by the Supreme Court of Ohio, and the city is immune from liability for any injuries caused by alleged defects in the road created as a result of the repaving.”
{¶ 6} The court thereafter certified a conflict to this court, finding that its decision conflicted with that of the Fifth District in Thompson v. Muskingum Cty. Bd. of Commrs. (Nov. 12, 1998), Muskingum App. No. CT98-0010, 1998 WL 817826, on the question “whether an edge drop on the berm of a county or city road, in and of itself, constitutes a nuisance within the meaning of R.C. 2744.02(B)(3)?”
{¶ 7} The case is now before this court upon our determination that a conflict exists (case No. 2000-2141) and upon the allowance of a discretionary appeal (case No. 2000-2004). 91 Ohio St.3d 1477, 744 N.E.2d 774, and 91 Ohio St.3d 1478, 744 N.E.2d 775.
{¶ 8} We concur in the judgment of the court of appeals that the trial court properly granted summary judgment in favor of the city based on the political subdivision immunity provided by R.C. Chapter 2744. We respond to the issue certified to us by clarifying that an edge drop on the berm of a county or city road does not, in and of itself, constitute a nuisance within the meaning of R.C. 2744.02(B)(3). We recognize, however, that circumstances may exist in which a defect in the berm arising after the design and completion of construction of a roadway, including a defect creating an edge drop between the pavement and the adjoining berm, would fall within the definition of “nuisance” as used in R.C. 2744.02(B)(3). In such a circumstance, the political subdivision could fit within the exception to immunity provided by R.C. 2744.02(B)(3), assuming that the political subdivision had actual or constructive notice of the existence of that nuisance, and that it could not establish any of the defenses provided by R.C. 2744.03.2
*346{¶ 9} The Political Subdivision Tort Liability Act is codified in R.C. Chapter 2744 and was enacted in response to the judicial abolishment of the common-law doctrine of sovereign immunity for municipal corporations in Haverlack v. Portage Homes, Inc. (1982), 2 Ohio St.3d 26, 2 OBR 572, 442 N.E.2d 749, and Enghauser Mfg. Co. v. Eriksson Eng. Ltd. (1983), 6 Ohio St.3d 31, 6 OBR 53, 451 N.E.2d 228. See Franks v. Lopez (1994), 69 Ohio St.3d 345, 347, 632 N.E.2d 502. The Act established statutory tort immunity in some cases in which political subdivisions, including cities, may otherwise be sued in negligence. See id.
{¶ 10} Within that statutory framework, R.C. 2744.02(A)(1) establishes a general grant of sovereign immunity by providing that a political subdivision is not liable for damages for injury, death, or loss to persons or property incurred in connection with the performance of a governmental or proprietary function of the political subdivision. The term “governmental functions” specifically includes “the maintenance and repair” of roads. R.C. 2744.01(C)(2)(e). However, R.C. 2744.02(B) lists several exceptions to the general grant of sovereign immunity. At issue in this case, as in Franks, is R.C. 2744.02(B)(3), which provides that political subdivisions are liable for injury caused “by their failure to keep public roads, highways, [and] streets * * * within the political subdivisions open, in repair, and free from nuisance * * *.”
{¶ 11} This court first interpreted R.C. 2744.03(B)(3) in Manufacturer’s Natl. Bank of Detroit v. Erie Cty. Road Comm. (1992), 63 Ohio St.3d 318, 587 N.E.2d 819. In that case we determined that a township’s duty under R.C. 2744.02(B)(3) to keep the road free from nuisance included the responsibility of ensuring that corn growing in the right-of-way of a township road did not obstruct a driver’s view of cross-traffic at intersections. Because we had no precedent interpreting the term “nuisance” as used in R.C. 2744.02(B)(3), we considered prior case law interpreting an analogous statute, R.C. 723.01,3 which imposes an affirmativé duty upon municipalities to keep their roads free from nuisance.
{¶ 12} After construing the case law interpreting R.C. 723.01, we held in Manufacturer’s that a “permanent obstruction to visibility, within the highway *347right-of-way, which renders the regularly travelled portions of the highway unsafe for the usual and ordinary course of travel, can be a nuisance for which a political subdivision may be liable under R.C. 2744.02(B)(3).” Id. at paragraph one of the syllabus. In support of that proposition, we reasoned that a political subdivision’s duty under R.C. 2744.02(B)(3) “extends to conditions in the right-of-way that directly affect the highway’s safety for the regular and ordinary course of traffic.” Id. at 321-322, 587 N.E.2d 819. We further observed that in determining a political subdivision’s duty to keep a road free from nuisance, whether under R.C. 2744.02(B)(3) (all political subdivisions) or 723.01 (municipalities), the focus should be on “whether a condition exists within the political subdivision’s control that creates a danger for ordinary traffic on the regularly travelled portion of the road.” Id. at 322, 587 N.E.2d 819.
{¶ 13} Significantly for purposes of the case at bar, the court in Manufacturer’s turned to R.C. 4511.01(UU)(2), which defines “right-of-way” as including “the roadway, shoulders or berm, ditch, and slopes extending to the right-of-way limits under the control of the state or local authority.” Id. at 322, 587 N.E.2d 819. We observed that “[t]he roadway, the space immediately above the roadway, the shoulder, the berm, and the right-of-way are all under the control of the political subdivision.” (Emphasis added.) Id. We held that a political subdivision has a “duty to keep the areas within its control free from nuisance, i.e., conditions that directly jeopardize the safety of traffic on the highway.” Id.
{¶ 14} In subsequent cases the critical inquiry established in Manufacturer’s has remained “whether a condition exists within the political subdivision’s control that creates a danger for ordinary traffic on the regularly travelled portion of the road.” 63 Ohio St.3d at 322, 587 N.E.2d 819. Most recently, in Harp v. Cleveland Hts. (2000), 87 Ohio St.3d 506, 721 N.E.2d 1020, we reviewed the principles established in Manufacturer’s and Franks and reaffirmed the Manufacturer’s rejection of the view that “liability under R.C. 723.01 or 2744.02(B)(3) is limited to physical conditions in the roadway itself and does not extend to adjacent property.” Harp, 87 Ohio St.3d at 511, 721 N.E.2d 1020. See, also, id. at 515, 721 N.E.2d 1020 (Cook, J., dissenting).
{¶ 15} In Harp the court rejected the city’s argument that it was entitled to immunity under R.C. Chapter 2744 based solely upon the fact that a tree limb that fell upon a highway had not physically obstructed or impeded the flow or visibility of traffic until it fell. That is, in Harp we held that a condition external to the roadway could create a danger to the traveling public on the highway.
{¶ 16} In the same way, an edge drop or similar condition may indeed constitute an actionable danger to persons operating their vehicles in a reasonable manner on the highway. Accord Dickerhoof v. Canton (1983), 6 Ohio St.3d 128, 6 OBR 186, 451 N.E.2d 1193 (rider killed when motorcycle struck pothole in
*348road’s shoulder). Indeed, such a circumstance appears to have occurred in Thompson v. Muskingum Cty. Bd. of Commrs. (Nov. 12, 1998), Muskingum App. No. CT98-0010, 1998 WL 817826, which the certifying court of appeals herein identified as being in conflict with its judgment in the case at bar. In Thompson, a UPS driver was forced to maneuver his vehicle onto the berm in order to avoid a collision when another motorist crossed the center yellow line. As in the case at bar, the left tires of the delivery truck remained on the paved portion of the road while the right tires moved on the berm. The berm dropped off six to eight inches from the level of the road. The driver lost control of the van in attempting to maneuver the vehicle back onto the road. In Thompson the court of appeals determined that the drop-off may have constituted a nuisance, that the driver may well have acted reasonably, and that the trial court erred in entering summary judgment for the county.
{¶ 17} A finding that a genuine issue of fact exists as to whether any particular edge drop constitutes a “danger for ordinary traffic on the regularly travelled portion of the road” under Manufacturer’s, 63 Ohio St.3d at 322, 587 N.E.2d 819, is not, by itself, determinative of whether that edge drop constitutes a “nuisance” for purposes of R.C. 2744.02(B)(3). In Franks, we expressly declined to expand the definition of that term to embrace design and construction defects, which “simply do not constitute a nuisance” even if those defects result in a dangerous condition. Id., 69 Ohio St.3d at 349-350, 632 N.E.2d 502. Accordingly, while a failure to maintain a traffic control device that is already in place, such as allowing a reflectorized sign to lose its capacity to reflect, may constitute a breach of duty to keep roads “free from nuisance,” the initial decision to post, or not to post, a sign is discretionary and therefore protected by immunity under the Act. Id. at 348-349, 632 N.E.2d 502.
{¶ 18} Thus, read in harmony, Manufacturer’s and Franks establish a two-pronged test to determine whether a condition in the right-of-way of a road should be deemed a nuisance for purposes of R.C. 2744.02(B)(3). To withstand a motion for summary judgment, the plaintiff must satisfy the first prong of the test by establishing that the condition alleged to constitute a nuisance creates a danger for ordinary traffic on the regularly traveled portion of the road. To satisfy the second prong of the test the plaintiff must establish that the cause of the condition was other than a decision regarding design and construction. If the dangerous condition is the result of negligent design or construction decisions, the condition does not constitute a nuisance, and immunity attaches. Both prongs of this test require the resolution of issues of fact.
{¶ 19} In short, no bright-line test can be stated as to whether an edge drop on the berm of a county or city road constitutes a nuisance within the meaning of R.C. 2744.02(B)(3). .An edge drop may constitute a nuisance for purposes of that *349statute where the drop resulted from a failure to maintain a preexisting shoulder or berm; where the particular edge drop is found, in light of all the surrounding facts and circumstances, to render the regularly travelled portions of the highway unsafe for the usual and ordinary course of travel; and where the political subdivision has failed to correct the defect upon being charged with actual or constructive notice of its existence. If, however, a dangerous edge drop is the result of design or construction, it is under our precedent and, by definition, not a nuisance within the scope of R.C. 2744.02(B)(3).
{¶ 20} Haynes produced no evidence to raise any genuine issue of fact to rebut the city’s contention that the edge drop here at issue was the result of the implementation of a discretionary design plan. Thus, alleged negligence in that plan is protected by the general grant of immunity provided by R.C. 2744.01(A)(1). Specifically Haynes asserts, in effect, that the plan for constructing the berm separately from the repaving contract was defective, and that the city was negligent in determining the order in which it addressed the berming process. This is a challenge to the design of the repaving project, which falls within the scope of immunity provided by R.C. Chapter 2744.
{¶ 21} On the facts before it the trial court correctly granted summary judgment to the city of Franklin because the facts demonstrated that the edge drop complained of was incident to the design and construction of the road improvement the city had determined, in its discretion, to implement. Summary judgment in favor of the city was appropriate because the plaintiff did not establish any genuine issue of fact otherwise.
Judgment affirmed.
Resnick and F.E. Sweeney, JJ., concur. Lundberg Stratton, J., concurs in part. Douglas, Pfeifer and Cook, JJ., dissent. Pfeifer, J., dissents.. The judgment in Stevens was reversed by this court in Stevens v. Ackman (2001), 91 Ohio St.3d 182, 743 N.E.2d 901, on unrelated grounds.
. R.C. 2744.03 also establishes additional defenses for political subdivisions, including so-called “discretion defenses.” Franks v. Lopez (1994), 69 Ohio St.3d 345, 347, 632 N.E.2d 502. R.C. 2744.03(A)(5), for example, provides, “The political subdivision is immune from liability if the injury, *346death, or loss to persons or property resulted from the exercise of judgment or discretion in determining whether to acquire, or how to use, equipment, supplies, materials, personnel, facilities, and other resources unless the judgment or discretion was exercised with malicious purpose, in bad faith, or in a wanton or reckless manner.”
. {¶ a} R.C. 723.01 provides:
{lib} “Municipal corporations shall have special power to regulate the use of the streets. Except as provided in section 5501.49 of the Revised Code, the legislative authority of a municipal corporation shall have the care, supervision, and control of the public highways, streets, avenues, alleys, sidewalks, public grounds, bridges, aqueducts, and viaducts within the municipal corporation, and the municipal corporation shall cause them to be kept open, in repair, and free from nuisance.”
