The Linnemeier Building is located at 422 E. Kirkwood Avenue. It had housed a dental practice and Blast Off Balloons. It sits atop the Jordan River Tunnel, which was not upgraded during The Big Dig Project due to structural concerns for the building.
In 2009 developer Michael Eaton of Rubicon Construction proposed razing the building in favor of a new four-story structure on the location. If that were to happen the tunnel underneath would be upgraded.
