Buffalo's statuesque Albright-Knox Art Gallery will begin to pack up by the end of 2019 and will remain closed while construction on a $155 million expansion takes place over the next two years.

The A-K 360 project includes a new building with 269,000 square feet for art exhibits, new amenities for visitors and outdoor architecture. That project is set to be completed in 2021.

In the meantime, the museum will hold off-site programming at a new space called Albright-Knox Northland starting in early 2020. That will be located on the 600 block of Northland Avenue, on Buffalo's east side, where the city continues to redevelop.

See side-by-side how one of the big projects will look  — Common sky will place "a light canopy of glass and mirrors over the courtyard of the 1962 Building that reaches down into the space with a funnel-like column."
