The Susquehanna and Waterford Turnpike Company was, by special act of February 22, 1812, chartered to construct a turnpike from Waterford in Erie county to the Susquehanna river near the mouth of Anderson’s creek in Clearfield county. The company was duly organized, and in the year 1820 built its road on its route between terminals, from Brookville, Jefferson county, to Franklin, Venango county. About the year 1856 this part of the pike was abandoned, and was taken in charge as a public road by the supervisors of the townships through which it ran. By act of 10th of April, 1862, the plaintiff company was chartered, and authorized to appropriate so much of the old Waterford turnpike as lay between the west line of Clarion county and the borough of Brookville, Jefferson county; and further, to charge such tolls as were allowed to be collected by the charter of the old company. It was also, by the fifth section of the same act authorized to erect and maintain a bridge over the Clarion river, where the old turnpike struck the river, and to charge tolls for the use of the bridge to an amount not exceeding such tolls as were authorized to be collected by the turnpike company for two sections of five miles each on the turnpike. By a subsequent act, that of 14th of April, 1863, the same company was authorized to reconstruct all of the old pike east of the Allegheny river, and further, to increase its rate of tolls for use of the road between the Allegheny river and Brookville about nineteen per cent. In 1865 the plaintiff built the bridge over tbe Clarion river, half a mile west of the borough of Clarion. It is a wooden covered bridge, about 221 feet, single span, with stone abutments and proper approaches: this took the place of one erected by the company two years before, but which had been swept away by a flood. The company went on collecting tolls for the use of the bridge, until April sessions, 1890. of Clarion county, when proceedings were instituted under the act of 8th of May, 1876, to acquire the *249bridge for the county, that it might thereafter be made free to the public. That act provides that on petition of at least twenty taxpayers to the court of quarter sessions, setting forth that a bridge is necessary to the accommodation of the traveling public, and that the payment of tolls is burdensome, the court shall appoint viewers who shall view and report whether the bridge is necessary as a free bridge for public accommodation, and whether the payment of tolls is an unjust burden on the traveling public and the people of the townships where the same is located; also the amount of damages which shall be sustained by the company owning -the bridge by the taking thereof. The right of appeal from the award on confirmation of the report by the common pleas was given to both the company and the county. In this case, viewers were appointed, who awarded damages in sum of $2,500; the company appealed, and on trial the jury awarded $7,081.61; on motion for new trial, the court directed the company to re'mit all in excess of $5,700, or new trial would be granted; on the company filing paper remitting excess, judgment was entered on the verdict against the county for $5,700. The county now appeals, assigning eight errors. All these alleged errors hinge on the construction or effect to be given to the fifth section of the act of 1862, which authorized the erection of the bridge. That section reads thus:

“ That should the commissioners of Clarion county elect to erect a county bridge over the Clarion river at or near the point where the Susquehanna and Waterford turnpike road strikes said river, and maintain and keep the same in repair, the company hereby incorporated shall have no power or authority over the same, but it shall be the exclusive property of said county, and under its control; but should the said county commissioners neglect and refuse to erect a bridge as aforesaid, the company aforesaid are hereby authorized to erect a toll bridge at its own expense and costs, and to have the exclusive control thereof, and to levy a toll on all persons and property passing over the same, not to exceed in amount that authorized to be collected on two sections of the turnpike, and on all footmen, not to exceed two cents for each and every passage.”

The reasonable interpretation to be given this section, when read in connection with the whole act authorizing the appropri*250ation of the roadbed, of the old turnpike company, is that the authority to construct and maintain the bridge at this point is a grant distinct and separate from the general powers to maintain and operate a turnpike. In fact, the only reference to the turnpike is that part of the section which measures the authorized tolls by the amount allowed to be charged on two sections of the turnpike. When the authority to erect the bridge is given, the right of the county is expressly saved; if it declines to build, then only is the company authorized to build. The company has authority to build at a particular point, and to have the exclusive control thereof; then, it will have two separate properties and franchises; the turnpike road and the bridge. If the county had built the bridge, it would not have affected the right of the company to operate its road on each side of it; the bridge would have been free, but the traveler over it would have had no right of free passage through the turnpike gates. So the county, by the proceedings, acquired the bridge, but not a part of the turnpike, and by this acquisition it not only took the structure and approaches, but a distinct and separable part of the company’s franchise. The question then simply is what damage did the company sustain by the taking of the bridge and the loss of the franchise ? All the evidence as to how much the company lost on the turnpike and bridge as a whole is to a great extent immaterial, because it has but little if any bearing in a determination of the value of the bridge to the company. The rule is that adopted by the court below, as stated by this court in Mifflin County Bridge v. Juniatia County, 144 Pa. 374, and in Montgomery County v. Bridge Company, 110 Pa. 54. “ Where a bridge is taken by a county for public use under act of May 8th, 1876, the measure of damages is the value of the property to the owners, not to the county taking it, and such value is to be ascertained, not only by the cost of the structure, but by the value of its franchises. The value of its franchises depends largely upon its earning power.” The court, after stating this rule, then called the attention of the jury to the elements entering into an estimate of the value such as the cost of the structure, the net tolls, and market value of stock if it had a market value. There was evidence that the original cost of the structure was ten to twelve thousand dollars; that when taken by *251the county in 1890, it had been in existence and use about twenty-five years; there was conflicting evidence as to the extent of deterioration by time and use: some of the evidence tending to show it was almost worthless and would soon have to be replaced, and other evidence that.it was about as substantial as when first erected. Then as to the net receipts of tolls for the five years prior to the taking, it was shown they averaged about $700 per year. At times part of the net receipts were appropriated to keep up the turnpike road ; but this in no way tended to depreciate the value of the bridge. That there were net earnings, was important; what use was made of them was immaterial.

All the conflicting evidence was submitted to the jury in a very full and careful charge, the summing up of which is the instruction requested in plaintiff’s third point: “ That the true measure of damages is just compensation for the loss suffered by plaintiff in consequence of the taking by defendant of plaintiff’s property, being the substructure, superstructure and approaches of the bridge, together with the franchise or right to take tolls, and the jury have no right to find less.” There could have been no more correct statement of the law.

The argument of appellant, that the supplement of April 14, 1863, established a new rate of tolls for both turnpike and bridge companjq in place of that in the act of 1862, and that no tolls could thereafter be charged for the bridge separate from the turnpike company, cannot be sustained. The act of 1863, throughout, has reference to tolls on the turnpike road, and by no reasonable construction can it be made to include the bridge expressly authorized by the fifth section of the act of 1862, for which a special rate of tolls was fixed.

Even if the bridge were an inseparable part of the turnpike, and the whole should, as appellant contends, be treated as one corporate property, the part taken, the bridge, should be estimated at its true value, when compared with the whole. If the gross receipts of this part were larger in proportion and the net also than any other part of the property, and the bridge be taken from them, they lose that part of their property which is of the greatest value. The principle contended for by appellant that, if the corporate property as a whole yields no net income a part of it is of no value, is palpably unsound; the *252productiveness of a comparatively small part of a railroad, canal or turnpike may maintain for public use and keep in repair, under the charter, the whole; with this valuable part the corporate property may be kept in serviceable condition, and opex-ated, without dividexxds, until a change of times, increases in population, more rigid economy, or wiser management, makes the whole remunerative; take away this productive part, and the corporation is at once hopelessly bankrupt. Common observation has demonstrated that many corporate enterprises have become sources of lax’ge income to their stockholders, by the mere ability to survive for a few years, in the absence of any net income from the property as a whole.

It will be noticed the act of 1876 provides that when paying tolls is too burdensome to the public, the county is authorized to acquire the bridge; the argument of the learned counsel fox-appellant tends to the conclusion that if the property be burdensome to the owners, the public should come to their x-elief by confiscating it. This is a misapprehension; the act is not based on a sort of guardianship of improvident owners, who persist in holding on to unproductive property, but oxx the idea that private property may be taken for public use, when the interest of the public is thereby promoted; but when thus taken, the public must pay for it in reasonable damages.

All the assignments of error are overruled and the judgment is affix-med.
