Talk:Interstate Highway System

Speed limit

I put a on the statement that the nation had a national speed limit enforced by federal law. It wasnt a law that said you cant have a speed limit over 55mph, in fact many states had highways with a higher speed limit (such as New Jersey) during that period. What Congress and Reagan did was to say "you have a speed limit over 55 mph and that highway isnt eligible for as much federal highway money". Congress actually has no authority to directly tell states what the speed limit can be, even on interstates, but as with alot of things, it CAN bully states to conform to federal standards by withholding money.Camelbinky (talk) 16:07, 6 May 2009 (UTC)

Link to Interstate 50

I just created an article on Interstate 50 that talks about why there is no Interstate 50, but I can't find a place in this article to link to it. Anyone know of one?? Georgia guy (talk) 18:50, 25 June 2009 (UTC)

Full Formal Name citation

Just for reference purposes, the first reference:

confirms the full formal name of the system.

Citations Needed in Extremes

I have just marked most of the bullets in the Extremes section with the {{cn}} tag -- not because I dispute any of these facts, but to encourage documentation. I know many editors object to what they perceive as overuse of this tag and in most cases it is best to use the {{unreferenced}} tag for a section, but I thought tagging each fact would be a better way to keep track of progress toward complete documentation. By the way, I chose not to tag the 49°N as it seemed to fall into the category of general knowledge that need not be specifically referenced. I'm not sure what would be the best form of documentation for some of these. YBG (talk) 00:22, 2 August 2009 (UTC)

Speed limit extremes

I don't think that section is necessary. The maximum speed limit in the country - 80 mph - can be/should be/is mentioned in the speed limit section. But the lowest speed list will be long I think. So far we have two routes listed as 40mph. I-180 in Wyoming is 40mph, I-68 in Cumberland Md is 40mph as well. I-70 through Breezewood is 35mph. Not to mention the sourcing issues. --MPD ^{T / C} 19:33, 13 August 2009 (UTC)

If there is a 35mph section, that would eliminate the host of 40mph sections. I was quite surprised to hear about anything below 50mph, so I think the slowest speed is interesting information. If either the fastest or slowest list gets to be more than a few (3? 4?), then add the expression 'and others'. For now, why not include the 35mph information? YBG (talk) 03:31, 15 August 2009 (UTC)

Okay so thoughts on this: I-70 follows US 30 on a short surface segment through Breezewood, Pa. The speed limit is 35mph. It's not Interstate-grade, but it is still a true speed limit for a section of Interstate highway. I feel it should count as the lowest speed limit and replace the 40mph sections listed. Thoughts? --MPD ^{T / C} 03:13, 16 October 2009 (UTC)

Shortest segment

The distinction of "not crossing State boundary" does not make sense to me:

• Shortest segment not crossing a State boundary: 0.11 mi (0.18 km): I-95 in the District of Columbia, where it crosses the Potomac River on the Woodrow Wilson Bridge.[53]

Although DC is not a state, I would claim the particular I95-segment runs from the VA to the MD state boundary.

I thought quite a while about how to word this particular one -- how to be brief and yet still accurate. Before my edit, it read 'The shortest Interstate route segment within a state (or federal district)', which seemed a bit wordy. As the boundaries of DC with its neighbors are in fact the state boundaries of Maryland and Virginia, I thought the present wording was both accurate and concise. What about something like this:

• Shortest segment not crossing a State boundary: 0.11 mi (0.18 km): I-95 on the Woodrow Wilson Bridge across the Potomac River where it briefly briefly crosses the southernmost tip of the District of Columbia between its borders with Maryland and Virginia.

Or maybe someone else has a better way to express it concisely and accurately. Edit boldly! YBG (talk) 06:31, 30 August 2009 (UTC)
