The design for the Columbus binocular telescope has been completed and the project is now proceeding to the construction phase. The two 8 meter f/1.2 borosilicate honeycomb mirrors will give an effective collecting area of 11.3 m and a baseline of 22 m for interferometry. The optics are supported on an exceedingly compact and rigid 'C-ring' mount with a lowest eigen frequency of around 10 Hz. The system will be housed in a corotating enclosure and will be located on Mt. Graham in southeastern Arizona. Instrumentation priorities have been established for the telescope and conceptual designs are now under development. The Columbus Project is a collaboration between the Osservatorio Astrofisico di Arcetri, Italy, the Ohio State University and the University of Arizona.
