 Between 1997 and 1999 , The Adler Planetarium added a sky pavilion to the original 1930 architecture . When it did so , the roads were moved and the sundial was moved to its current location . The move was performed by contractors of the Adler Planetarium in two phases . First , the sculpture was removed and placed in storage to make way for the current roadway . It was later moved to its current position after the new roadway was built and the old roadway was replaced with a walkway . Now , a u @-@ turn in Solidarity Drive runs through the original location of the sundial , and the sundial is located on the walkway that replaced the previous roadway that went around the planetarium . The new location and the u @-@ turn can be seen on a Museum Campus map . This construction was contemporaneous with the $ 100 million project that reconfigured of traffic around the Museum Campus and caused Lake Shore Drive to be moved during the mid @-@ 1990s .
