HealthLine

The HealthLine, formerly known as the Silver Line, or as the Euclid Corridor Transportation Project, is a bus rapid transit (BRT) line run by the Greater Cleveland Regional Transit Authority in Cleveland and East Cleveland, Ohio, United States. The line runs along Euclid Avenue from Public Square in downtown Cleveland to the Louis Stokes Station at Windermere in East Cleveland. It began operation on October 24, 2008. Its current name was the result of a naming rights deal with the Cleveland Clinic and University Hospitals of Cleveland. The HealthLine is denoted with a silver color and abbreviated simply as HL on most RTA publications.

The HealthLine's ridership peaked at 5.08 million rides in 2014, but has declined to 1.7 million rides in 2023 following the impacts of COVID-19. It is the busiest bus route in Cleveland.

The Healthline is tied with Connecticut Transit'sCTfastrak and Muni'sVan Ness Bus Rapid Transit as the second-top rated BRT system in the United States, each with a Silver rating according to the Institute for Transportation and Development Policy (ITDP) BRT Standard. Only ABQ RIDE's Albuquerque Rapid Transit (ART) has achieved the top rating of Gold.
