U.S. Route 101
The nearly highway's northern terminus is in Tumwater, Washington: the route remains along the Olympic Peninsula's coastal perimeter west, north, and east; the northernmost point on the highway is in Port Angeles. The southern terminus of US 101 is in Los Angeles at the East Los Angeles Interchange, the world's busiest freeway interchange.
Florida State Road 101
SR 101 begins at an intersection with SR A1A at the northern end of Atlantic Beach, heading north on four-lane divided Mayport Road through a portion of Jacksonville. The road passes through areas of homes and businesses before becoming a five-lane road with a center left-turn lane and coming to an intersection with the eastern terminus of SR 116. Following this, the state road heads between wetlands to the west and wooded neighborhoods to the east as a four-lane undivided road. SR 101 reaches its northern terminus at the entrance to Naval Station Mayport.
