U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).
New Hampshire Route 101
NH 101 is a two-lane surface road from its western terminus in Keene to the western terminus of New Hampshire Route 101A in Milford. From there, NH 101 splits off to the south and becomes a two-lane limited-access highway that bypasses Milford and Amherst, becoming a two-lane surface road just north of Amherst. At the eastern terminus of New Hampshire Route 114 in Bedford, NH 101 becomes a four-lane limited-access highway. It expands to six lanes upon merging with Interstate 293 in Manchester, and eight lanes upon merging with Interstate 93. East of I-93, NH 101 narrows to four lanes. The route remains a four-lane expressway until exit 12 (Interstate 95) in Hampton, where NH 101 becomes a two-lane freeway at exit 13. At an interchange with U.S. Route 1, it becomes a two-lane surface road to its terminus in Hampton Beach.
