Interstate?

[edit]

I have a question.

If Interstate 180 is not met to Interstate standards, how did it become signed as an interstate in the first place?

I think interstate-guide.com might have something on that. --Rschen7754 (talk - contribs) 04:16, 13 August 2007 (UTC)[reply]
  • Usually routes connect to otehr interstate is an interstate. I-180 connects to I-80 I believe is the west end. In California I-710 is an interstate because it cross with I-10 in Monterey Park, CA. Most auxiliary interstates is less than 60 miles, and most often they don't cross state line. Auxiliary interstates is a connect interstate, and technically, they are not an interstate. I-405 is 73 miles long in California, and it connects to both part of I-5 both San Diego and Golden State Freeways. I-605 For example connects to i-405 and I-5. In other terms those routes is not interstate itself but it hooks up to be an interstate. I hope this is right question you want to ask.--Freewayguy Call? Fish 02:46, 23 July 2008 (UTC)[reply]

And also I-180 in WY may not be an freeway. Its exit is on interstate-guide.com. The exit is simply west end, 5th St, 9th St, and east end.--Freewayguy Call? Fish 02:48, 23 July 2008 (UTC)[reply]

I wonder if the UK motorway standards could act as some signpost to this, if the Interstate designers and engineers were thinking along the same lines; it's not actually out-of-standard to have a reduced speed limit, at-grade junctions or even traffic lights on a piece of road (especially a sliproad / ramp / spur) that's designated as a motorway (autoroute, autobahn, freeway), just very heavily discouraged. You can even find some undivided 2 (or 7...) lane stretches with the designation. It does sometimes occur, though pretty much never on the "main line", merely on connectors that run for a mile or two, typically into cities or through pieces of difficult terrain.
The MAIN defining feature of a motorway, freeway/interstate, etc is that it's designated exclusively for the use of registered motor traffic, and normally particular classes of such to boot (minimum speed/engine capacity/power, tyre, suspension, trailer standards are involved, for example); often also there's some kind of breakdown lane to minimise obstruction of traffic flow, and the default speed limit tends to be higher.
And, as noted above, any approach road that ONLY exits onto a motorway/interstate - or, slightly less commonly, only gives you the choice of either heading onto that road or returning to where you came from - and pretty much any that do nothing but connect two of them, is automatically also considered part of the same class.
So, are cyclists, mopeds, farm tractors and harvesters allowed to ride/drive down I-180? Army tanks? Pedestrians, farmers driving animals between fields? Or is it exclusively higher-speed, surface-friendly, self propelled wheeled conveyances, and attempting to use something else to pass along that stretch of highway is actually an illegal offence? And also, at the intersections, is cross traffic allowed to join I-180 in either direction, and is I-180 traffic allowed to leave onto the side streets, or are turn restrictions in place and it's simply a case that they were too poor (or mean, or constrained by geography/architecture) to build proper bridges and overpasses?
(Specimens given in evidence, off the top of my head; the M5-M50 junction, the A38(M), the former A6144(M) and a couple of similar roads that still retain their "M" designation, including IIRC one "Bxxx(M)" spur, a sharply curving overpass joining the M6 to M1 that now sports a 50mph speed limit instead of the usual 70 (not to mention a lengthy section of the M4 through Port Talbot), the toll booths on the M6 Toll (30 mph, light- and barrier-controlled), anywhere that variable speedlimits or red/green light lane controls are used, traffic-light based flow-metering systems on various sliproads... and more than a few Austrian and Swiss 2-lane or 2+1 Autovias... plus, on the other side of the same pedantic-terminology coin, some trickier parts of the A55 which are "A55(M)" in all but name - they're grade separated, and what would normally be called "non motorway traffic" is prohibited (using a huge, text-heavy sign as they're not allowed to just use that term), but geography and budget prevented them being built to full standard ... gradients too steep, curves too tight, lanes too narrow, lack of hard shoulder (breakdown lane), 50 and even 30mph limits in some places... and some of them then spill out directly into non-GS, all-traffic sections... at 70mph!) 193.63.174.211 (talk) 10:19, 9 May 2013 (UTC)[reply]
