Merriweather Post Pavilion can expect shorter lines this summer, as the outdoor music venue installs more concession stands and restrooms in renovations that began in February.

The changes are part of the first phase of a multiyear, $19 million-plus facelift, which will also include integrating new seats and raising the pavilion and stage roofs. The goal is to get the bulk of the renovations complete in 2017, when Merriweather celebrates its 50th anniversary.

“Let’s take Merriweather to the next generation or two generations down the road,” Merriweather general manager Brad Canfield said during a Tuesday morning tour of the site, as he pointed out changes in the biggest transformation in the venue’s history.

Howard Hughes Corp. plans to modernize the 47-year-old amphitheater’s aging facilities and help it compete for bigger acts. County officials and residents see the renovation as a critical component of downtown Columbia’s revitalization.
