The reason why this particular route change was made was so that the same level of Metrobus service could be provided on the segment of the former Z1 Metrobus Route between the Verizon Chesapeake Complex & Glenmont Metro Station, via Muskgrove Road, Fairland Road, Tamarack Road, Randolph Road, & Georgia Avenue (MD 97), as the Z1 Metrobus Route was discontinued during this time.
