The station opened on April 11, 1920 with the initiation of rail service by the Cleveland Interurban Railroad on what is now Van Aken Boulevard from here to Shaker Square and then to East 34th Street and via surface streets to downtown.
At the time, Lynnfield was the end of the line.
 In 1923 the station building was built at a cost of $17,926 to provide a waiting room for passengers.
 It also housed tobacco and newspaper stands.
 The newspapers were delivered to the station by rapid transit.
The building included outside shelters on both sides.

After the line was extended to Warrensville Center Road in 1930, Lynnfield no longer functioned as the end of the line and the station building was not needed.
 The building was leased to a series of tenants.
 
In 1980 and 1981, the Green and Blue Lines were completely renovated with new track, ballast, poles and wiring, and new stations were built along the line.
 The renovated line along Van Aken Boulevard opened on October 30, 1981.
 The improvements at Lynnfield included renovating the original station building, providing benches in the waiting shelter, and enclosing the  waiting shelter in glass.
