A plywood perimeter has been erected around the plaza at Pentagon Row as heavy construction has gotten underway on a major renovation project

A backhoe and other construction equipment being used to excavate the center of the plaza. So far outdoor restaurant seating has remained open at the plaza, but instead of overlooking the center courtyard, the view from the outdoor patios is blocked by plywood boards around the construction. Today, those board were being painted black.

As reported earlier this month, the renovations include an expanded ice rink during the winter, a turf lawn during the summer, revamped outdoor dining areas, 1,500 square feet of new retail and dining space, lighted water fountains and a stone fire pit.

Construction is expected to wrap up this fall, according to Pentagon Row owner Federal Realty Investment Trust.
