RADFORD â City Council will continue to explore the possibility of building an amphitheater after it received two conceptual designs from a local engineering firm. Over the last few years, several council members have expressed an interest in an outdoor venue as part of the cityâs plan to increase its appeal as a place to visit in the New River Valley. Local design firm Thompson & Litton presented council with two concepts for an amphitheater complex, both located on a roughly one-acre plot of land southwest of the Glencoe Mansion and next to the Kollmorgen plant. Both designs call for enough room for roughly 2,900 occupants â including performers and vendors â but the size of the stages and the amount of people allowed at an event could vary depending on multiple factors, according to Thompson & Littonâs Barry Collier, who gave the presentation to council at last weekâs council meeting.
