This is an appeal from a summary final judgment for Metropolitan Dade County upon the basis of sovereign immunity. The judgment was upon the defendants’ third party complaint against the County for failure to properly maintain and repair a roadway and failure to warn of a dangerous condition. The trial judge relied upon this court’s decision in Cheney v. Dade County, 353 So.2d 623 (Fla.3d DCA 1977), quashed by the Supreme Court of Florida in Com *635 mercial Carrier Corp. v. Indian River County, 371 So.2d 1010 (Fla.1979).1
The Supreme Court’s decision in Cheney v. Dade County and the companion case of Commercial Carrier Corp. v. Indian River County dictate reversal of the summary judgment appealed.
Accordingly, the judgment is reversed and the cause remanded for further proceedings.
Reversed and remanded.
