An Electron Ion-Collider (EIC) has been highlighted as the highest priority for new construction in the DoE Office of Nuclear Physics. This is a very challenging accelerator that aims to achieve high luminosity and polarization over a large center of mass span. Alternative designs are pursued at Jefferson Laboratory (JLAB) and Brookhaven National Laboratory (BNL) each capitalizing on the existing CEBAF and RHIC facilities respectively. I will overview the design options at JLAB and BNL, the accelerator R&D necessary to validate the designs and will explore areas of potential synergy and collaboration.
