We are asked in this appeal to determine the limits of governmental immunity under the Texas Tort Claims Act. Tex.Civ.Prac. & Rem.Code Ann. §§ 101.001-.109 (West 1986 & Supp.1994). Rhonda Maxwell appeals from a take-nothing summary judgment rendered in favor of the Texas Department of Transportation (“the Department”). We will affirm the judgment of the trial court.
BACKGROUND
Maxwell was severely injured early one morning when her car veered off U.S. Highway 281 and came to rest in a culvert adjacent to the road. Maxwell asserts that she swerved off the road to avoid hitting a deer. The Department built and continues to maintain both the culvert and highway. Maxwell sued the Department, alleging that the culvert constituted a special defect or, in the *463 alternative, an ordinary premises defect, and that her injuries were proximately caused by the Department’s failure to warn of the culvert or make the culvert reasonably safe. At the time of the accident the only warning device notifying motorists of the culvert’s existence was a post with three amber reflectors.
The Department moved for summary judgment on the basis of governmental immunity under sections 101.056(2) and 101.061 of the Texas Tort Claims Act. The Department also argued that Maxwell could not prove all of the elements of a premises cause of action. Because the summary judgment order did not state the basis of the trial court’s judgment, Maxwell brings four points of error attacking all three grounds stated in the Department’s motion for summary judgment.

TEXAS TORT CLAIMS ACT
A state agency, such as the Department, may not be sued for damages unless the Texas Tort Claims Act waives the state’s governmental immunity for the alleged wrongful act.
Lowe v. Texas Tech Univ.,
However, the Tort Claims Act does not provide a waiver of immunity when a claim is based on an agency’s performance or nonperformance of an act committed to agency discretion. Id. at § 101.056(2). Nor does it apply to agency acts or omissions committed before January 1, 1970. Id. at § 101.061. The Department asserted both of these exceptions to liability in its motion for summary judgment.
The Tort Claims Act also provides that an agency shall not be liable for its failure “initially to place a traffic or road sign, signal, or warning device if the failure is a result of a discretionary action of the governmental unit.”
Id.
at § 101.060(a)(1). However, when the danger constitutes a special defect, the state has an obligation to place a warning device, and will not be immune from liability if it fails to do so.
Id.
at § 101.060(c). Maxwell attempts to circumvent the Department’s immunity from claims based on discretionary acts by arguing that the culvert constituted a special defect.
Id.
at §§ 101.022(b), .060(c). In the alternative, she argues that the culvert was a premises defect. Whether a condition constitutes a special defect or a premises defect is an issue of law for the court to decide.

DISCRETIONARY ACTS
The Department moved for summary judgment contending that Maxwell’s complaints regarding the placement of the culvert and its safety features are essentially complaints about the design of the culvert, an issue committed to agency discretion. A governmental entity’s discretion in the design of roads and bridges, which includes the installation of safety features such as guardrails and barricades, is protected from liability by section 101.056(2) of the Tort Claims Act.
Wenzel v. City of New Braunfels,
In her first point of error Maxwell insists that the trial court erred in granting summary judgment based on immunity for discretionary acts because the Department’s decisions regarding the placement of the culvert and its safety features involve professional or occupational discretion not protected by section 101.056(2).
See Eakle v. Texas Dep’t of Human Servs.,
Actions involving occupational or professional discretion are devoid of policy implications. Examples include decisions made in driving a mail truck,
3 K. Davis, Administrative Law Treatise
§ 25.08 at 403-4 (Supp.1982); or the decision by a drama instructor to use a glass rather than a plastic prop in a university production.
Christilles v. Southwest Texas State Univ.,
Decisions regarding the design of a highway and the installation of safety features, however, do not fall into this category. It is not proper for a court to second-guess the agency’s decision that some other type of marker or safety device would have been more appropriate than the amber reflector at. issue, or that the culvert was placed too close to the highway. To do so would displace the authority of the agency responsible for making such decisions.
See Ayoub,
Contrary to Maxwell’s argument, a “professional,” such as an engineer, may use his or her skills in designing adequate safety features for a highway without subjecting the process to judicial review as an occupational or professional class of agency action. Thus, even though the Department may have used engineering expertise and discretion in the planning and design of the culvert, the action remains in the informed discretion of the agency and exempt from liability under section 101.056(2).
Maxwell next argues that the Department is not entitled to immunity from liability pursuant to section 101.056(2), because the culvert constitutes a special defect. See Texas Tort Claims Act § 101.060(c) (state liable for injuries arising from failure to warn of special defects). As such, appellant argues that the agency has a mandatory, rather than discretionary, duty to warn motorists of the dangerous condition, and section 101.056(2) does not apply. However, the mandatory duty to warn of special defects provides an exception only to those exemptions from liability described in section 101.060 of the Tort Claims Act. Id.
Section 101.060 exempts the government from liability for injuries caused by: 1) the Department’s failure to initially place a traffic signal or warning device if the decision is within the agency’s discretion; 2) the absence, condition or malfunction of a traffic signal or warning device if the Department has not had sufficient notice to remedy the defect; and 3) the removal or destruction of a traffic signal or warning device by a third person if the Department has not had sufficient notice to replace the sign or device. Id. at § 101.060(a). Section 101.060 further states that if the injury is caused by a special defect, the mandatory duty to warn of the special defect abrogates governmental immunity. Id. at § 101.060(c). We note that the Department did not assert section 101.060 as a ground for summary judgment.
In her pleadings, Maxwell stated that the Department failed to warn her of the culvert’s existence. Summary judgment evidence presented by both the Department and Maxwell shows, however, that motorists were warned of the culvert by a “type 2” marker *465 consisting of a post with three amber reflectors. Maxwell’s response to the Department’s motion for summary judgment suggests that the Department breached its duty to Maxwell by placing the culvert too near the road, failing to provide guardrails or barricades, and using the wrong type of warning device. These claims do not complain of the absence of a warning device, but, rather, the adequacy of the marker already in place.
Cases that have found special defects under section 101.060(c) involve the state’s failure to provide any warning device at all.
Harris County v. Eaton,
Even if Maxwell’s claim involved a complete failure to warn of the culvert, thereby triggering the mandatory duty to warn, we do not believe that the culvert constitutes a special defect. Special defects have been held to be those obstructions that present unexpected and unusual dangers to ordinary users of the highway that are beyond the normal course of events.
Payne,
We believe that the culvert at issue here is not a special defect because it, too, would not be encountered by ordinary users of the highway. Like the plaintiff in
Payne,
Maxwell travelled off the road before coming into contact with the culvert. Special defects are obstructions that affect normal highway traffic.
Eaton,
Because the Department has established its immunity based on section 101.056(2), we overrule the first point of error.
NO MATERIAL FACT ISSUES
In her second point of error, Maxwell argues that she has raised various fact issues that should defeat the summary judgment in favor of the Department. However, all of the alleged facts relate to the adequacy of the Department’s warning and the steps taken by the agency to make the culvert safe. When an appellee, such as the Department, has conclusively established that it cannot be held liable because of governmental immunity, any facts relating to its liability are immaterial.
Eakle,
ACTS OR OMISSIONS BEFORE JANUARY 1, 1970
Maxwell’s third and fourth points of error concern the Department’s assertion of section 101.061 as an alternative basis for governmental immunity. The Department argues that it was entitled to summary judgment because the Tort Claims Act “does not apply to an act or omission that occurred before January 1, 1970.” Texas Tort Claims Act § 101.061. If the Department proves that the culvert was completed before 1970 and has remained in the same condition since that time, then, as a matter of law, the Department is entitled to immunity under section 101.061.
Tarrant County Water Control & Improvement Dist. No. 1 v. Crossland,
Maxwell argues that the Department’s failure to upgrade or improve the safety features of the culvert during renovation of the highway in 1979 constitutes an act or omission that occurred after January 1, 1970. We disagree. The act or omission is the actual building of the structure.
University of Texas-Pan Am. v. Valdez,
In response, Maxwell argues that interpreting section 101.061 to bar claims based on pre-1970 highway designs encourages the state to ignore highway defects because they existed before 1970. She asserts that the state has been given free rein to ignore unsafe highways and dangerous conditions simply because of the defect’s age. This argument, however, disregards the intent of section 101.061 which is to “provide for the abolishment of governmental immunity without causing havoc.”
Chapman,
CONCLUSION
Because we hold that the Department has satisfied its burden of proof to support governmental immunity under section 101.056(2) and section 101.061 of the Texas Tort Claims Act, we affirm the judgment of the trial court.
Notes
. Maxwell points out that the original design for the highway in 1959 contemplated the erection of several timber posts along the culvert to serve as a guard fence. She argues that the Department failed to conclusively prove that the fence was removed before 1970, and, thus, a fact issue remains defeating summary judgment. The Department's summary judgment evidence shows, however, that the wooden posts were replaced before January 1969, and since that time there have been no changes made to the site by the Department.
