I was at Asoke yesterday. I don't normally go there. I noticed for the first time that they have created a path for traffic to get through the intersection westbound on Sukhumvit. (It may have been there a lot longer, but this is the first time I saw it.) Basically as you approach Asoke from the East, you turn Left but then they have a set of traffic cones allowing you to immediately u-turn around the obstructed intersection and continue westbound on Sukhumvit. Only 1 lane, but it shouldn't be too slow.
