States with lower speed limits than pre-1974: 17 [c] The introduction to 70 or 75 mph (112 or 120 km/h) speed limits was in effect that year. The introduction to 80 mph (almost 130 km/h) limits was in about 2005, and Texas introduced 85 mph (136 km/h) in 2011.
In 1941, a speed limit of 70 mph (113 km/h) was established, only to be reduced to 35 mph (56 km/h) during the war years (1942–45). After WWII, the limit was raised to 70 mph on the four-lane sections, with the two-lane tunnels posted at 50 mph (80 km/h) for cars and 40 mph (64 km/h) for trucks.
As of May 15, 2017, 41 states have maximum speed limits of 70 mph (113 km/h) or higher. 18 of those states have 75 miles per hour (121 km/h) speed limits or higher, while 7 states of that same portion have 80 mph (129 km/h) speed limits, with Texas even having an 85 miles per hour (137 km/h) speed limit on one of its toll roads.

Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour. It is used in the United Kingdom , the United States , and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.
For example, the maximum speed limit is 75 mph (120 km/h) in northern Maine, varies between 50 and 70 mph (80 and 115 km/h) [51] from southern Maine to New Jersey, and is 50 mph (80 km/h) in New York City and the District of Columbia. [50] Currently, rural speed limits elsewhere generally range from 65 to 80 miles per hour (105 to 130 km/h).
The study analyzed data on more than 700 participants aged 70 or older. Those who took omega-3 and vitamin D supplements regularly over three years appeared to have a slower rate of biological aging.
[2] [14] The average speed over the entire route is 70.3 mph (113 km/h). [2] [17] Speeds are limited by the route the corridor takes through urban areas, and there are several speed restrictions below 60–80 mph (97–129 km/h) over bridges or through tunnels that are over a century old.
