Interstate 90


I-90 is huge!! It is the largest interstate in the United States and stretches from coast to coast, at a whopping 3,020 miles of pavement.

The eastern end of I-90 terminates in East Boston right after it crosses the Boston Harbor, where it becomes Highway 1A. The western end of the massive interstate is its junction to Interstate 5, just southeast of downtown Seattle. It truly is a coast-to-coast interstate!
