McGrew was incorporated as a village in 1911 when the Union Pacific Railroad was extended to that point. By 1912, it was home to a Presbyterian church, which ran services until 1971. McGrew boomed in the 1920s; at that time, businesses included several stores, a post office, a railway depot and grain elevator, a saloon, an industrial yard, agricultural buildings, and a hotel. The church was purchased by the Platte Valley Bible College and renamed the McGrew Community Church, and again renamed the Oregon Trail Chapel in 1986. A school was added in 1920. The post office shut down in 1986. Today, very few buildings are still in use and most are abandoned.
