The Electron-Ion Collider (EIC) is being designed for construction at Brookhaven National Laboratory. Activities have been focused on beam-beam simulations, polarization studies, and beam dynamics, as well as on maturing the layout and lattice design of the constituent accelerators and the interaction region. The latest design advances will be presented.

The Electron-Ion Collider (EIC) is envisioned as the next DOE Nuclear Physics facility. BNL is proposing eRHIC, a facility based on the existing RHIC complex as a cost effective realization of the EIC project with a peak luminosity of 1034 cm-2sec-1. An electron storage ring with an energy range from 5 to 18 GeV will be added in the existing RHIC tunnel. The beams will collide in up to two Interaction Regions (IRs). Balancing conflicting experimental physics and machine accelerator physics demands with realistic eRHIC IR magnet designs requires new concepts and careful attention to detail. We review recent work aimed at reducing IR magnet cost and at avoiding risk associated with using a high-field Nb3Sn actively shielded quadrupole that was present in an earlier design.
