A proposed street-level alignment for the Purple Line could pass through Silver Spring’s new library.
One route, which would thread the light-rail line through downtown Silver Spring and onto Wayne Avenue, would cut through a plot at Bonifant and Fenton streets (above), according to the state transit administration.
The county is consolidating its hold on that plot so that it may build a new public library, Gary Stith, Silver Spring’s regional director, said at Wednesday night’s economic development committee meeting.
The possibility of a light-rail line rolling through the new library’s lobby worried some. Elizabeth Conklin and Kay Davis, of the Silver Spring Library advisory committee, said the sound of trolleys pulling into and out of a proposed station there could be disruptive.
Instead, the women recommended tunneling the Purple Line through the entire central business district.
The state transit administration should know whether the proposed alignment would travel at or below street level before the county embarks on the library’s design, Stith explained.
