The iconic Out of Town News kiosk in Harvard Square could undergo some changes in the near future. Cambridge officials have been assessing ways to enhance public open space in the area, including a rejuvenation of the 500-square-foot kiosk. The project would open up the kiosk, restore the structure, showing off the architectural detail through more lighting, and convert it into a flexible space with a variety of programming opportunities, according to Stuart Dash, director of community planning for the city’s Community Development Department.
