County use of city streets as bridge approach

Whenever any county constructs across any stream any bridge which is wholly or in part within the limits of any city within the county, the county may use as approaches for the bridge such portions as may be necessary of any street of the city leading to the bridge. The power, dominion and right of control over and to improve and maintain the portions of any street so used belong exclusively to the county.
