traffic is reduced to one lane and shifted onto the westbound half of the road). Another technique used is treating the rightmost hard shoulder as a travel lane. In the case of 6-lane freeways (3 in each direction), the third lane is often kept for the busier direction or the shoulder is opened up to allow for 4 lanes of traffic, but with little or no shoulder space (emergency breakdown areas are sometimes added, however). Usually, merge ramps on freeways, expressways and uncontrolled roads with interchanges have temporary "YIELD" or "STOP" signs for these situations.
361:...for basically the same reasons given by the anon editor of the "British Use of the word" section above. Contraflow as a temporary but non-emergency measure (ie planned in advance) is very common in motorway roadworks here in the UK, yet most of this article deals only with it in the US emergency sense. Even the "Highway reconstruction" section deals almost exclusively with the US. As it stands, the B-class rating for the U.S. Interstate Highways WikiProject is absolutely

No-one is monitoring this page as most of the states (unsourced) claims to have invented the concept. Usually in the past three years. I'm pretty sure that contraflow has been employed for emergency purposes since basically freeways were invented. It really should be started over from scratch. Does

I just added a disputed tag to the sentence stating that I-5 between
Seattle and Tacoma (Washington state) has a contraflow lane. I live in that area and have never seen any such lane. We have reversible express lanes between downtown and northern Seattle, but those are dedicated reversing lanes and

I believe it is commonly referred to as "contraflow lane reversal," in the U.S. at least, even if it is a bit redundant. And you could have "contraflow" without "lane reversal," if there are lanes on the roadway that normally flow in the opposite direction of traffic (e.g. a contraflow bus, HOV, or
513:
Overall, my issue is that, in terms of
Knowledge (XXG), I think it would be best if the subject of reversing a lane's direction of travel was divided based on whether the lane is part of a less-controlled surface street (and divided from oncoming traffic by a painted line) or part of a freeway (and
331:
My earliest memories of contraflow traffic is from people talking about its use in their coastal evacuation of
Hurricane Carla in 1961, so I doubt the concept was invented in 1980's as the article states. In addition Contraflow lane reversal has been used on I-35W in Fort Worth near the Texas Motor

No mention of the
British usage of the word, in particular, the way in which traffic is diverted to the opposing side of a motorway in order to close lanes, or even an entire side of the carriageway, for maintenance. Could some add this; I don't feel capable of a sufficiently clear explanation.
287:
Freeways (usually 4 lanes or more) that are undergoing reconstruction reduce both sides to one lane. In some cases, they will shift traffic onto one half making it a temporary two-lane freeway corridor. An example of this can be found here on Google Earth on
Interstate 10 in Arizona (eastbound

A prominent example of a freeway contraflow in progress can be found at the
Woodrow Wilson Bridge in Washington, DC. While construction is in progress on a parallel twin span, the recently-completed first span accommodates both directions (three lanes each way)."

I took a crack at balancing the article out by improving the lede to note the UK and US usages of the term and promoting the reconstruction section to co-equal status with the emergency evacuation material. Not perfect but I think it's better.

I rewrote the hurricane evacuation section from scratch, hopefully simplifying it, while adding links to the websites with the info on each states' plans. If there are non-US examples, I wasn't able to track any down with Google.
