This week brings us to an interesting interchange in Tianjin, China:
![[Please visit my site to see the map that would otherwise be embedded here]](http://www.triskele.com/images/map.gif)
This is the interchange of the Jingtang Expressway (京津塘高速公路), the Jinji Expressway (津蓟高速公路), and Tianjin’s Outer Ring Road (Waihuanxian)
The Jingtang Expressway (the upper northwest-southeast highway above) is a 4-lane tollway connecting Beijing with Tianjin. It was built in 1993, and is reported to be seriously plagued by high traffic loads arising from the growth of long-haul trucking and personal auto ownership in the past 15 years.
The Jinji Expressway (running southwest-northeast in the map above) connects the urban center of Tianjin with Ji County of Tianjin province.
And, of course, the Waihuanxian (the more impressive-looking northwest-southeast highway in the map above) is the outer ring road. Although it looks like a freeway in the above clip, in reality it is just a major road, not-fully controlled access.
