Pocomoke City was completed in 1961; the segment of highway between US 13 and MD 675 (now US 13 Business) became an extension of MD 250A. The original Pocomoke City bypass from US 13 to MD 756 was resurfaced with bituminous concrete in 1969, the same year work began to establish a four-lane divided highway from Pocomoke City to Snow Hill. The second, northbound carriageway of the highway was constructed from east of Pilchard Creek to Blades Road between 1969 and 1971 and from Blades Road to the south end of the Snow Hill bypass in 1970 and 1971. US 113 was relocated as a four-lane divided highway from its US 13 intersection to east of Pilchard Creek, over which a new bridge was built for the northbound carriageway, starting in 1972. The now-bypassed 1936 Pocomoke City bypass was redesignated MD 359 after the completion of the new bypass in late 1974. The two-lane Snow Hill bypass was built as the southbound carriageway of an eventual divided highway from its south end to MD 12 in 1971 and 1972 and from MD 12 to north of Snow Hill between 1973 and 1975; the latter section included a three-span bridge across Purnell Branch. The bypassed portion of US 113 through Snow Hill became MD 394 in 1976. MD 394 was redesignated US 113 Business after AASHTO approved the new designation at its spring 1997 meeting. Divided highway continuation Expansion of US 113 to a divided highway slowed in the 1970s. As with most major highway projects, the divided highway expansion projects received partial federal funding, and starting in 1970, those federally aided projects required environmental impact assessment under the National Environmental Policy Act. This new barrier slowed the completion of the divided highway between Milford to Dover. Maryland was subject to the same environmental assessment, but it was local activism that overcame state inaction in continuing divided highway construction along US 113 in that state. Completion of divided highway in Delaware The Negative Declaration for the expansion of US 113 from the north end of the Frederica bypass to US 113 Alternate at Little Heaven was issued in 1975, and construction began that same year. The Frederica–Little Heaven divided highway was completed in 1977. Design work for the divided highway from Little Heaven to Dover Air Force Base began as early as 1964, and considerable planning and design work was done
