The Rapid began operating bus service between Downtown Grand Rapids and Grand Valley State University in Allendale in 2000, funded by the university. The Route 50 "Campus Connector" grew into a popular service, with ridership increasing from 179,000 trips per year in 2002 to 1.4 million in 2012. This rapid ridership growth occurred in tandem with the growth of the GVSU campuses in Downtown Grand Rapids. The Rapid and GVSU increased peak-hour bus service to every six minutes, but still faced significant overcrowding on buses. The Rapid released a long-range plan in 2010, which included a number of proposed improvements to its services by 2030. The plan included bus rapid transit corridors on Division Avenue and Lake Michigan Drive, and also proposed better frequency and hours of service for standard bus routes. Detailed planning for the project began in 2012, when the
Federal Transit Administration awarded The Rapid a $600,000 grant to study options for enhanced transit service along Lake Michigan Drive. Construction began in April 2019, and was estimated to be complete for the Fall 2020 semester at GVSU. The first of the fleet of 16
compressed natural gas-powered buses was received in June 2019. Service on the Laker Line began on August 24, 2020, in the midst of the
COVID-19 pandemic. At the line's launch, bus capacity was limited, and face masks were required. The final cost of the line, including buses, stations, and road work, was $72.8 million. == Fares ==
