OPINION
This is an interlocutory appeal of the trial court’s denial of defendant/appellant Harris County’s plea to the jurisdiction. 1 Plaintiffs/appellees — the estate of Stephanie Ciccia, deceased; Luz M. Ciccia, as personal representative and as independent administratrix of the estate of Stephanie Ciccia, deceased; Luis Ciccia and Luz M. Ciccia, individually and as parents and next Mends of Stephanie Ciccia, and as sole heirs of the estate of Stephanie Ciccia, deceased; and Giovanna Cic-cia, individually — sued the County after Stephanie Ciccia died from injuries that she sustained in an automobile accident. Stephanie was a passenger in a car that crashed into a concrete culvert located at the end of an unfinished, unlit roadway.
In a single issue presented for review, the County contends that the trial court erred in denying its plea to the jurisdiction based on sovereign immunity. We must determine whether the road hazard here resulted from a flawed road design, for which the County does not waive its immunity from suit under the Texas Tort Claims Act, (TTCA), 2 or whether it was a premise or special defect for which the County is liable. Because we conclude the hazard here was a special defect, we affirm.
*752 Facts
As part of a capital improvement road project in Harris County, a median and several turn lanes were constructed on Barker-Cypress road near Keith Harrow Boulevard on what had previously been an undivided four-lane road. The engineering plans included a right-hand turn lane, intended to serve a proposed concrete plant, that was marked with striping, arrows, and the words “right turn only” on the road surface.
The lane was designed to turn into the driveway of the plant, but the plant was never built and no driveway was necessary. The designated right-hand turn lane remained, however, simply ending abruptly. At a later time, after this turn lane was constructed, the County permitted the telephone company to add a concrete culvert several yards beyond the end of the turn lane. This section of road was not lit; there were neither barricades nor signs to warn drivers that the road simply stopped short of a ditch containing a culvert.
Stephanie and Giovanni Ciccia were passengers in a car that drove into this lane at 10:00 p.m. at night, traveled past the end of the road, and struck the concrete culvert, killing Stephanie and injuring Giovanni. The Ciccias sued the County for faulty road design and construction and for fading to warn of a special or premise defect. The County filed a plea to the jurisdiction, which was denied by the trial court, and this interlocutory appeal ensued.
Plea to the Jurisdiction
In its sole issue on appeal, the County contends the Ciccias’ claims arise from its discretionary decisions regarding the road design and the placement of warning signs or traffic control devices, so there is no waiver of immunity.
As a preliminary matter, we first address the Ciccias’ contention that the County’s appeal was not timely filed. Although the Ciccias argue that the notice of appeal should have been filed within 20 days after the original order was signed, the rule does not contain the word “original” and the Ciccias offer no authority to support their argument. The order complained of was signed on January 17, 2003, and the notice of appeal was filed on January 23, 2003, well within the 20-day limit. Accordingly, we hold that the notice of appeal was timely filed. See Tex.R.App. P. 26.1(b) (“[I]n an accelerated appeal, the notice of appeal must be filed within 20 days after the judgment or order is signed”). We will therefore reach the merits of the County’s appeal.
Standard of Review
When deciding whether to grant a plea to the jurisdiction, the trial court looks only to the allegations in the plaintiffs pleadings, without considering their merits, to determine if any of the claims raised support its jurisdiction.
Baston v. City of Port Isabel,
Sovereign Immunity
In general, governmental entities are immune from tort liability under the
*753
doctrine of sovereign immunity unless the legislature has waived immunity.
Dallas Co. Mental Health & Mental Retardation v. Bossley,
However, the Tort Claims Act does waive a governmental unit’s immunity to liability based on violation of “the duty to warn of special defects such as excavations or roadway obstructions.” Tex. Civ. PRAC. & Rem.Code Ann. § 101.060(c);
State v. Rodriguez,
Whether a condition is a special defect is a question of law for the court.

Discussion
Flawed Road Design
The Tort Claims Act does not waive sovereign immunity for the discretionary actions of a governmental unit. Tex. Civ. Prac. & Rem.Code Ann. § 101.056(2);
Rodriguez,
Here, the road was initially designed with a designated right-hand turn lane marked with striping, arrows, and the words “right turn only” on the road surface. to serve a proposed concrete plant that was never built. Although the County’s construction of the right hand turn lane here was premature, and ultimately unnecessary, we acknowledge that its construction was part of the road design and
*754
not- a special defect. The design of a roadway is a permanent feature and thus not an unusual or unexpected danger.
See Villarreal v. State,
We hold that the County did not waive its sovereign immunity to liability for its initial design of the “right turn only” lane. Nevertheless, we conclude that the hazard here was not the result of a flawed road design, but instead resulted from the presence of a special defect. We reach this conclusion for several reasons.
Special Defect
Special defects “unexpectedly and physically impair a vehicle’s ability to travel on the road.”
Rodriguez,
The dangerous condition need not have been created or caused by the government unit to constitute a special defect for which the governmental unit has a duty to warn.
County of Harris v. Eaton,
The Ciccias rely in particular on this Court’s holding in
City of Houston v. Jean,
The culvert located beyond the end of the road onto which the “right turn
*755
only” lane directed traffic satisfies the definition of a special defect as a condition of the same kind or class as an excavation or obstruction that unexpectedly and physically impaired the Ciccias’ car’s ability to travel on the roadway. There was no indication that the road simply ended, and no lighting by which to see this at night. While the sudden ending of the road onto which traffic was directed could simply have been a nuisance if a car had become mired in unpaved earth, the culvert located just beyond the end of road presented an unusual and unexpected danger to ordinary users of the designated right turn lane. The culvert was not part of the roadway design; nor was the placement of the culvert an initial discretionary decision made in connection with the construction of the “right turn only” lane on Barker-Cypress Road. Rather, the culvert was added by a third party with the County’s permission after the right turn lane had been constructed; thus the County knew of this dangerous condition and had a duty to warn of the special defect.
See Payne,
Even though the construction of the designated “right turn only” lane here was an initial discretionary decision of the County that was subject to immunity under section 101.060(a) of the Civil Practice and Remedies Code, the County’s immunity to liability for failure to warn about the unlit culvert beyond the end of the road was still waived by section 101.060(b).
See Rodriguez,
The trial court did not err in denying the County’s plea to the jurisdiction.
We affirm the trial court’s order.
