That's almost what I have (bypass lane)
As for "carriageway", I think I was using it in the older sense of anything that could bear the weight of a carriage. The reason is that these diversions can take the cars over virtually anything -the Swedish often uses the term "vägbana". It can be a temporary overpass, a hard shoulder, another road, a lane on a motorway, a country lane etc. so I needed a general term. Do you have a better solution? (UK, not US English for this job) thanks |
