I-495 southbound along the Delaware River between Claymont and Edgemoor

Interstate 495 (I-495) is a 11.47-mile (18.46 km) long Interstate highway in the U.S. state of Delaware. The highway serves as a six-lane bypass of I-95 around the city of Wilmington. I-495 begins at an interchange with I-95 and I-295 near Newport to the southwest of Wilmington. From here, the road heads east to the Port of Wilmington, where it turns northeast and crosses the Christina River as it heads to the east of downtown Wilmington. Upon reaching Edgemoor, I-495 runs between the Delaware River to the east and U.S. Route 13 (US 13) to the west, continuing to Claymont. In Claymont, I-495 turns north and merges into northbound I-95 at an interchange with Delaware Route 92 (DE 92) just south of the Pennsylvania state line. Plans for a bypass of Wilmington to the east date back to 1948 and was incorporated into the Interstate Highway System in 1956. This interstate bypass was numbered I-495 in the 1960s. Construction on building I-495 took place during the course of the 1970s, with the entire length of the highway completed and opened to traffic in 1977. Between 1978 and 1980, I-95 was designated along the I-495 alignment while the South Wilmington Viaduct along I-95 was reconstructed; during this time the route through Wilmington was known as I-895. The US 13/DE 3 interchange in Edgemoor opened in 1988. In 2014, the bridge over the Christina River was closed due to tilting support columns until repairs were completed.
