The HealthLine (formerly known as the Silver Line and 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.
