US: the fastest and slowest motorways image

Many motorists outside the US have dreamed about cruising at high speeds on America’s long, straight for miles highways. What most of them don’t know is that around two decades ago, the national speed limit was just 55 miles (90 km/h).

Fortunately, even if speed limit free Autobahns are just in Germany, many US states have moved to update the speed limits. Among them – much to the appall of safety advocates – stands out Texas, which has the single fastest highway in the US (a stretch of toll road from Austin to San Antonio, opened in 2012, capped at 85 mph) as well as the fastest average allowable speeds. At the other end of the spectrum are the District of Columbia and Alaska, with the country’s lowest top and average speeds, according to research coming from the Governors Highway Safety Association, or GHSA.

The GHSA has factored in all the Lone Star States Interstates, state freeways and toll roads, as well as limited access highways, coming up with an average speed of 78.3 mph for Texas, which is 1.6 mph higher than the pursuing state of Idaho, with 76.7 mph. Utah and Wyoming also have top speeds in excess of 80 mph, while another 12 states have limits that push the 75 mph average. Alaska and the District of Columbia are the only two remaining states that have not pushed up the “double-nickel” limit, staying at the 55 mph level.
