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. The HealthLine's ridership peaked at 5.08 million rides in 2014, but has since declined by over 25% through 2018, with 3.7 million rides that year. The Healthline is tied with Connecticut Transit's CTfastrak as the second-top rated BRT system in the United States each with Silver rating according to the BRT Standard. Only ABQ RIDE's Albuquerque Rapid Transit has achieved the top rating of Gold. History Going back to the 1950s, the city of Cleveland considered alternatives for rapid transit along Euclid Avenue between downtown and University Circle. In 1985, the city commissioned a study called the Dual Hub Corridor Alternatives Analysis/Draft Environmental Impact Statement. The study estimated the cost of a subway along this corridor to be $1 billion and an option that involved a light rail component at $750 million. A further study in 1993 examined additional alternatives, including a bus rapid transit plan, which ultimately was selected by the RTA in 1995. Upon adoption by the Northeast Ohio Areawide Coordinating Agency in December 1995, the name of the project was changed from the Dual Hub Corridor to the Euclid Corridor. The plan included the Euclid Corridor busway, relocating five Red Line stations and right-of-way improvements on East 17th and East 18th Streets. At the time, the estimated cost of the project was $210 million with the federal government funding 80% of the cost. In 1996, the Federal Transit Administration provided $4.0 million in funds for initial engineering studies. The initial ridership projections were 29,500 boardings per day by 2025. In 1999, the plan was scaled back to include only the busway and a budget of $228.6 million was established with the city seeking a 59% federal government share, or $135.0 million. The final design was completed in 2002 and the project was funded
