The project will complete the existing half-diamond SR 518 interchange at Des Moines Memorial Dr. This phase will complete the eastbound off ramp. Phase elements include a two lane “Drop-Option” ramp, a bridge over 8th Ave S, retaining walls to minimize right of way requirements, storm drainage and illumination. Pedestrian improvements will occur on 8th Ave S and Des Moines Memorial Dr. The interchange will handle additional commercial traffic expected as the Northeast Redevelopment Area develops.
