Question: are there any places in the us with no speed limit

Answer: No, The highest speed limits are generally 70 mph (113 km/h) on the West Coast and the inland eastern states, 75--80 mph (121--129 km/h) in inland western states, along with Arkansas and Louisiana, and 65--70 mph (105--113 km/h) on the Eastern Seaboard. Alaska, Connecticut, Delaware, Massachusetts, New Jersey, New York, Puerto Rico, Rhode Island, and Vermont have a maximum limit of 65 mph (105 km/h), and Hawaii has a maximum limit of 60 mph (97 km/h). The District of Columbia and the U.S. Virgin Islands have a maximum speed limit of 55 mph (89 km/h). Guam, the Northern Mariana Islands and American Samoa have speed limits of 45 mph (72 km/h). Two territories in the U.S. Minor Outlying Islands have their own speed limits: 40 mph (64 km/h) in Wake Island, and 15 mph (24 km/h) in Midway Atoll. Unusual for any state east of the Mississippi River, much of I-95 in Maine north of Bangor allows up to 75 mph (121 km/h), and the same is true for up to 600 miles of freeways in Michigan. Portions of the Idaho, Montana, Nevada, South Dakota, Texas, Utah, and Wyoming road networks have 80 mph (129 km/h) posted limits. The highest posted speed limit in the entire country can be found on the Texas State Highway 130, and it is 85 mph (137 km/h).
