I was wondering whether there are any sites on the internet that display the speed limits of different streets. Something that would show a map of all the roads with the speed limits, for example, and not just the speed of the expressways (where bicycles aren't allowed to ride on). I think it would be helpful to some people, especially those who perfer to ride on roads with vehicles traveling at lower speeds and would chose their route around those roads. Does any such site exist?

I can ride on expressways in Colorado.

Not in Massachusetts.

Fixed. This is pretty common throughout the western US where alternatives don't exist with mixed results. I-84 in Oregon has sections that you have to ride along the Columbia River that include some very narrow bridges. They are a bit scary.

Chalupa102, if you do a google search with the terms "state speed limit map" you can find lots of speed limit information by individual states. I haven't seen anything that gives speed limits nationally, however.

Technically, in Colorado, an expressway is any divided road with only partial limited access. You can ride on every expressway in CO. You can ride on only some freeways

Yes, I purposely pick nits.

While technically correct, your post gives the impression that you can ride on any multilane highway in Colorado. Since most people...myself included...don't distinguish properly between freeways and multilane highways, the conclusion one could reach is that you can ride any expressway or freeway. This isn't the case. While you can ride some freeways in Colorado and the west you can't ride all of them...it depends on the availability of adjacent routes.

I don't pick nits...too much...but I prefer clarity

Simplify -- the gov't calls them "Interstates", for Interstate Highway. With the notable exceptions expressed elsewhere, most do forbid bikes (and anything incapable of maintaining 45mph+ speeds).

My GPS shows the speed limits of most (but not all) road. This is useful information as a driver trying to stay legal. As a cyclist... ... not so much IMO. The speed of motor traffic is hardly the deal-breaker speaking for myself. Most municipalities limit the speed of town traffic to ~25mph. Bigger roads have 35 and 45. Google will show you the relative sizes of most roads and you should be able to figure out what speed of traffic they carry pretty easily. Where I live that might mean adding 3 miles(!) to a trip just to avoid a stretch of 35mph traffic... I don't know about you but for me that means drinking that can of "Handle It" and going out there with confidence.

Go to "street view" in google maps and surf up and down the streets that you are interested in until you see a speed limit sign.
