Interstate 5

Interstate 5

Interstate 5, often called I-5, is a very important road along the West Coast of the United States. It runs close to the Pacific coast from Mexico all the way up to Canada. This big highway connects three states: California, Oregon, and Washington.

I-5 is special because it is the only main highway that reaches both the Mexican and Canadian borders. When you travel south past the Mexican border near San Diego, the road changes and becomes a road in Mexico. When you go north past the Canadian border in Blaine, Washington, the road becomes a road in Canada.

This highway links many big cities. In California, you can visit San Diego and Los Angeles. In Oregon, you can see Portland. And in Washington, you can travel through Seattle. I-5 helps millions of people travel safely between these places.

I-5 was built in 1956 as part of a big plan to make roads better across the United States. Before that, there were older roads, but I-5 made travel faster and easier. Today, I-5 is still very busy, and many people use it every day to go to work, visit friends, or explore new places.
