Everyone has that one road they trust. The road where traffic is light and speeds are high. Unfortunately, such roads are exceptions to the norm. Often, we're stuck taking routes where the average speeds are slower than the posted limit. Ever wondered which American roads are the best in terms of average speed? Forbes put together a list of five routes that it feels are the fastest.

5. Arizona State Route 77 – 4.8 miles long, average speed of fastest five percent is 81 miles per hour.

4. Eastbound MI-5 Michigan Highway – 4.9 miles long, average speed of fastest five percent is 81 miles per hour.

3. California State Route 73 – 14.8 miles long, average speed of fastest five percent is 81 miles per hour.

2. Oklahoma State Highway 33 – 24 miles long, average speed of fastest five percent is 83 miles per hour.

1. Northbound Arizona State Route 79 – 17.6 miles long, average speed of fastest five percent is 88 miles per hour.

These are major routes with traffic that tends to run quite a bit more quickly than the surrounding roadways. Did Forbes get it right or are there some roads you know of that they might have missed? Sound off in the comments.

      Both of those Arizona State Routes originate from Tucson. Looks like people just can't get out of there fast enough! haha

      So on Northbound Arizona State Route 79 will the driver go back in time upon reaching 88mph?

      81mph for the 73 is probably pretty accurate. Speed is limited by enforcement rather than traffic though. Its the one road in Southern California where one could go upwards of 100mph regularly, only limited by the frequent patrol cars.

        When I was living in the area, the 73 was awesome to make big speed runs. The big roll on from Fairview Rd at the very start all the way to Jamboree Rd, there isn't really anywhere for a cop to sit. At least a few years back there wasn't. There are a few very memorable vehicles where the dial turned past the double century mark, but I never got GPS tracking to verify. Either way, that stretch of road during the late morning and early afternoon is one of the fastest roads I have ever been on.

        Not mentioned in the article, but it's a toll road.

        It's one of Orange County's toll roads. So you pay to drive on it as well as pay for any ticket you may get.

        This is true. I've almost never seen the actual highway part busy. The stretch of road in town coming off of the 57 is always busy due to roadwork, but once you actually get on the highway part of the 73 it's easy to get past the century mark.

      Forbes is obviously clueless. Hell, in Texas there are places where the speed limit is 85 mph, and I-90 between Rapid City ans Sioux Falls, SD, probably averages over 90...The highway patrol complained that the Impalas they had to patrol in simply couldn't run down speeders from a dead stop on the side of the highway before they got out of sight. Forbes needs top stick to financial news and quit trying to be all things for all people. They remind me of the former GM CEO who when asked what car GM offered comparable to a new Ford Taurus, replied "a two year old Buick". Problem was, he believed it.

        Yup in west Tx on I-10 the legal speed limit is 80 mph and there are cars going faster than that.

      Your headline is the fastest roads in America, and yet you show a picture of the 405?

        That's probably the slowest road in America.

      just to compare in 1995 the average speed of all cars on the AutobahnĀ“s 12,000km was 134km/h (83mph)..what is exciting speed for the faster 5% in 2011 today in the USA was the average crusing speed for every grandma/pa dady/momy newbee soccermom etc in 1995 in Germany...today the speed is even faster. It is amazing that we have two completely point of fews of "fast" ... here we are highspeedjunkys and in the USA they are accelerating fetishs :)... here realy no one cares if a car is one car lenght quicker from one red light to the next if it can throw you down the Autobahn 10 or 20km/h faster is all that matters :)

      I don't know about any of these, but in 2000, heading east out of Salt Lake City on I-80, I had to keep my Civic in 4th to keep up with the flow of traffic, mainly European sedans, and I don't think the needle on my speedometer dipped below 100 much. Beautiful, straight roads with a great line of sight all around and seemed to be smart drivers understanding how to get around slower traffic. Great time. Therefore...I-80?

      GA 400 - Average speed during the day and no rush hour...around 90 mph all the time!!!

      I-10 in West Texas has a posted speed limit of 80 mph, pretty sure the top 5% drives this road at well over 80 mph. http://www.houstonfreeways.com/modern/2007-01-07_80mph_west_texas.aspx

      Pretty much any interstate in California with minimal congestion = 80mph, especially in SoCal. I-15 between San Diego and Temecula, traffic will regularly approach 90 in the fast lane. I-5 up the central valley, you won't get pulled over if you're under 85 and won't get a ticket unless you're over 90. I-210 between Pasadena where it meets up to I-5 might as well be the autobahn, with the exception of the 2 days a year they're running a massive speed trap.
