In 1977, South Bethany's sewer system was completed, and the community installed its first two traffic signals, located on Coastal Highway at the north and south ends of the town. Also in that year, South Bethany received a federal grant to construct its first town hall, located on land Iggie Hall had donated for that purpose; the town hall opened in 1978. In January 1981, the Delaware Supreme Court lifted Sussex County's ban on construction on the dune, and development of the beach area resumed.
