The route I take home, Friday evening, about 5ish. ---

\>\> They chopped temporary routes through the Darien gap, winching the vehicles across bad spots, and rafted across the Atrato Swamp in Colombia. I think we can safely classify that as a discontinuity _\__ ---

What about the ancient Silk Route, all the way from China to Europe? ---

> [@](#): > > _Originally posted by Fiver \* > \*\* I can imagine a road that goes from Western Europe all the way into Russian Asia, which would probably be longer, but I don’t know that such a road exists._\* [This map](http://www.lib.utexas.edu/maps/commonwealth/russia_rel94.jpg) indicates there are continuous road connections from Spain/Portugal across Europe through Russia, and on into China, reaching the East China Sea. At least from this map, it would appear that there is no direct road connection to Vladivostock. However, if there were it would seem to be possible to drive as far east as Magadan on the Sea of Okhotsk. That route looks to be at least 7,000 miles/11,000 km, probably much more. It would theoretically be possible to drive from South Africa to either Manchuria or possibly Siberia. If one is looking for the longest connected system of roads, that’s got to be it. ---

I seem to recall that shortly after World War II a highway was completed through Pakistan, Iran, Iraq and into Turkey. For a brief period of time it was apparently possible to drive from Spain to India, and from there through the Ledo Road to central China. Political instability has since made such a journey theoretical at best, even if that connecting highway has been maintained. Probably not a single road, but a very impressive road network nevertheless. I’ll see if I can dig up some more details. ---

I met a guy in 1975 who had bussed with a group all the way from the U.K. to India. (Thanks, **Sofa King**. It wasn’t easy to find that map on the net.) ---

> [@](#): > > \*Originally posted by Sparrow \* > \*\*What about the ancient Silk Route, all the way from China to Europe? \*\* The Silk Route (or Silk Road) was not a single road, but several different roads. [Cite.](http://www.ess.uci.edu/~oliver/silk.html#3) > [@](#): > > The description of this route to the west as the `Silk Road’ is somewhat misleading. Firstly, no single route was taken; crossing Central Asia several different branches developed, passing through different oasis settlements. The routes all started from the capital in Changan, headed up the Gansu corridor, and reached Dunhuang on the edge of the Taklimakan. The northern route then passed through Yumen Guan (Jade Gate Pass) and crossed the neck of the Gobi desert to Hami (Kumul), before following the Tianshan mountains round the northern fringes of the Taklimakan. It passed through the major oases of Turfan and Kuqa before arriving at Kashgar, at the foot of the Pamirs. The southern route branched off at Dunhuang, passing through the Yang Guan and skirting the southern edges of the desert, via Miran, Hetian (Khotan) and Shache (Yarkand), finally turning north again to meet the other route at Kashgar. Numerous other routes were also used to a lesser extent; one branched off from the southern route and headed through the Eastern end of the Taklimakan to the city of Loulan, before joining the Northern route at Korla. Kashgar became the new crossroads of Asia; from here the routes again divided, heading across the Pamirs to Samarkand and to the south of the Caspian Sea, or to the South, over the Karakorum into India; a further route split from the northern route after Kuqa and headed across the Tianshan range to eventually reach the shores of the Caspian Sea, via Tashkent. ---

Just as an aside, I believe the longest straight stretch of road in the world is the Gunbarrel Highway in Western Australia (Although some ppeople seem to say it is a section of the Eyre Highway that traverses the Great Australian Bite) ---

> [@](#): > > \*Originally posted by nth \* > \*\*how about the road must have same name? > > this is a lot easier. hehe \*\* Well, the Trans-Canada Highway qualifies by this test. 🙂 If you take total mileage, it’s 7,821km/4,860 miles long. > [@](#): > > \*Originally posted by cmkeller \* > **There is, but I think the Deadhorse (AK) to the beginning of the gap in Panama stretch is longer than the unbroken portion of the Trans-Canada highway, from Vancouver to whatever the terminus is at Prince Edward Island where it becomes a water route to continue in Nova Scotia.** Ah, but you don’t have to go to P.E.I. to get to Nova Scotia on the Trans-Canada. The TCH branches in New Brunswick. One stretch runs to Confederation Bridge to connect with PEI, but another branch runs directly to Nova Scotia: [TCH in New Brunswick](http://www.transcanadahighway.com/newbrunswick/tch.htm) [TCH in Nova Scotia](http://www.transcanadahighway.com/novascotia/tch.htm) So, it’s possible to drive from Vancouver, B.C. to Sydney, Nova Scotia, without taking a ferry. The [mileage chart for the TCH](http://www.transcanadahighway.com/general/mileage.htm) doesn’t include Sydney, N.S., but if we use the distance from Vancouver to Halifax as an approximation, it’s around 6,071km/3,772mi. Now, depending on what people mean by a discontinuity, I think there’s a good argument that the most accurate measurement is from Victoria B.C., on Vancouver Island, to St. John’s, Newfoundland & Labrador. There’s regular ferry service between the mainland (i.e. Newfoundland) and the rest of Canada, and between coastal B.C. and Victoria. The ferry services are steady, reliable, and an integral part of the highway system. You drive your car on, and drive your car off. Neither one is a discontinuity, like the Darien gap, in my opinion. (I’ve ridden on both ferrys.) If you accept that argument, the distance from Victoria to St. John’s is 7,184 km/4,464mi.
