The PA 413 (Pine Street) interchange has a rendering as can be seen in the color roll plot on the project website. Roundabouts were investigated for the interchange; however, single lane roundabouts caused traffic backups onto US 1 and two-lane roundabouts would have required more property acquisition and would not have performed any better than traffic signals from a safety standpoint. As noted, traffic signals require less property acquisition than a two-lane roundabout and do not require any additional total property acquisitions.
