580 Split Not far from our office at Mills College in Oakland, California, the 580 Split is a risky jumble of ramps, overpasses, and interchanges, where highways cross, merge, intersect, and branch out in every direction. 580 Split, an annual journal, is both the convergence and divergence of many roads: a place of risk and possibility. We publish innovative and risk-taking fiction and poetry and strive to find the hidden places where they converge and venture forward.
