SARASOTA -Sarasota residents and visitors will soon see a rainbow of colors reflecting off the Ringling Bridge. The completion of its column light retrofit project is slated for this Thursday. The Florida Department of Transportation will upgrade the bridge using new energy efficient color LED lighting technology. Work on the $178,000 job started in June of 2019. FDOT says the color-changing lights will be comparable to Jacksonville, Miami, Pensacola and Tampa bridges.
