(Maryland Transit Administration)According to The Washington Post, Prince George’s County, Md. residents are urging MTA to change the design for the Riverdale Park station, particularly plans for a 26-foot-high wall on top of which the light rail station platform will sit.Residents have nicknamed the structure the “Trump wall,” and believe the structure would block businesses from being seen from the road. According to Washington, D.C. CBS affiliate WUSA, plans for the wall came after Maryland Governor Larry Hogan made changes to the Purple Line design. “Retained fill walls” at Riverdale Station were among the changes made to cut costs, according to Governor Larry Hogan’s office, but the height of the structure wasn’t listed.The 16.2-mile light rail route connecting Montgomery County and Prince George’s County is expected to begin service in 2022.
