Although the C7 Metrobus route did not go through anymore additional route changes, the C7 Metrobus Route replaced the segment of former "Calverton Express" Line Metrobus Routes Z7 & Z17 between Centerpark Office Park in Beltsville, MD & the intersection of Tech Road & Industrial Parkway in Fairland, MD, via Beltsville Drive, Calverton Boulevard/Broadbirch Drive, & Tech Road, which were also discontinued on September 26, 2004.
