There’s a glimmer of hope for the bridge in Rock Island State Park. After being closed for years, Tennessee Valley Authority officials are reviewing the safety concerns of reopening it.“We are working to resolve the public access and security issues,” said TVA spokeswoman Barbara Martocci. “Nothing is definite yet on what TVA will do or when.”According to Martocci, the Great Falls plant manager met with several TVA personnel from various departments to walk down the dam and bridge to look for opportunities for safety improvements for both plant personnel and the public, as well as security options.
