Travel directions

The highway begins at a major interchange with Interstate 95, which runs from Baltimore to Philadelphia, and Interstate 295, which runs as the New Jersey Turnpike to New York City. I-495 has 2×3 lanes and it passes through the east of the city of Wilmington, on the bank of the Delaware River more than 2 kilometers wide. The highway does not pass straight through the center, but just east of it through undeveloped area. Wilmington has a population of about 73,000, and is a center of its own outside of Philadelphia. The 6-lane motorway runs in a number of places directly over the bank of the Delaware River, with only a railroad track separating the highway from the river. At Claymont, I-495 rejoins Interstate 95, which then continues directly in Pennsylvania to Philadelphia.


Construction of I-495 began in 1973, when parallel I-95 had already been completed. The entire route opened in 1978 and served as Interstate 95 around Wilmington between 1978 and 1982, as the current route west of Wilmington from I-95 was reconstructed. Although it was the most recent highway in Delaware, already in the 1990s the concrete road surface developed in France had to be completely replaced due to the poor condition of the road surface.. Traffic to Philadelphia is encouraged to use I-495 instead of I-95 past Wilmington, due to the higher speed limit and increased number of available lanes. Discussions are underway to reroute I-95 over I-495. However, the mayor of Wilmington has rejected this idea.
