In 1960, design work on FAI-3 was underway. The route of FAI-3 was numbered as I-495 in 1962. In 1968, structural design for bridges along I-495 was underway. The same year, the first construction contracts began with three demolition contracts, the building of a culvert under the Penn Central railroad line at Holly Oak Creek, and the relocation of a section of US 13 to the west to allow for room to build I-495. In 1970, work continued on relocating US 13 along with the construction of bridges carrying the interstate over Stoney Creek. A contract was awarded to build I-495 between Edgemoor and I-95 in Claymont in 1971. The same year, work was underway on building the bridge over the Christina River. Design work on the interstate was completed at this time. The following year, construction contracts were awarded to build I-495 south of the Christina River and to stabilize the road near Cherry Island. Paving was also underway between the Christina River and Edgemoor. In 1973, contracts were let to build structures along the freeway between the Christina River and Edgemoor. Work on the highway between New Castle Avenue and the Christina River bridge was finished in 1975. In 1976, the first section of I-495 was opened between US 13 and I-95 in Claymont. The same year, the bridge carrying the highway over Edgemoor Road was completed. In June 1977, the remainder of I-495 was completed and opened to traffic. On June 28, 1978, the American Association of State Highway and Transportation Officials (AASHTO) approved rerouting I-95 along the I-495 alignment. However, AASHTO disapproved renumbering the alignment of I-95 through Wilmington as I-595. On October 27 of that year, AASHTO gave conditional approval for I-95 through Wilmington to be designated as I-195 from I-95 near Newport north to US 202 while the route from US 202 north to I-95 in Claymont would become I-395. I-895 was designated along the conditionally approved route of I-195 and I-395 on June 25, 1979. In 1980, the South Wilmington Viaduct along I-895 was reconstructed. On November 14, 1980, I-95 and I-495 were returned to their original alignments, with I-895 decommissioned. In 1988, an interchange was built at US 13 and DE 3 in Edgemoor. This interchange was numbered as exit 4, which resulted in the US 13 interchange in Claymont being renumbered from exit 4 to exit 5. In February 1988, a
