In Portland, traffic congestion is cool. In fact, they deliberately eliminated planned freeways when they wrote up their "Portland Plan" (the area was supposed to have ten freeways, but "leaders" decided that we could get by with just I-5, I-84, I-205, and the short little chunk of freeway that runs between the Marquam and Fremont bridges. While carping about "carbon footprints", "green&sustainable", and the need to recycle, city "leaders" have no problem with slowing traffic to a crawl, despite the increased emissions generated by their tactic.
In England, by contrast, they're going in the opposite direction; spending 15 billion pounds on a radical expansion and modernization of the country's roadways while removing bottlenecks. It's the largest upgrade in a generation (and if you've ever driven there, you know they could use it). Their revolutionary idea involves (gasp!) cutting congestion!
And in an especially un-Portland move, they're going to (gasp!) ban bicycles from the roadways! Whereas Portland removes vehicle lanes from existing roads to create "bicycle boulevards" while increasing congestion, England's moving the other way; they're widening roads, adding lanes, tearing out their exasperating roundabouts, and taking down traffic signals in favor of flyover ramps.
