roads cross the river in three places, at u.s. route 113 (in millsboro), delaware route 24/delaware route 30 (also in millsboro), and delaware route 1 (at indian river inlet in the delaware seashore state park). with the indian river inlet in a fixed place beginning in 1928, it became possible to build a bridge to span it, and the completion of the ocean highway (present-day delaware route 1 and now known as coastal highway) between rehoboth beach and bethany beach in 1933 prompted delaware to build a span to connect the northern and southern segments of the highway. since 1934, six bridges have spanned the inlet, all known informally as the indian river inlet bridge, although all but the first officially were named the charles w. cullen bridge. the current indian river inlet bridge opened in 2012.
