the hay i make is deciding to pull off some snaps while driving past the roadworks ;)
one of the chicanes. the red and white block things (no idea what the proper name for these things are) mark out the border of a section of the road that's been dug up. white dotted lines towards the sides denote lane boundaries, and yellow mark the new "kerb extensions". the latter two are somewhat faint in the photo.
don't know that i'll be able to quite get the desired "before and after" effect, given that all these shots were taken while travelling in a vehicle and thus harder to reproduce position/timing! oh well, one step at a time :)
