It is often the case on schemes like this to have a split contraflow with two lanes on one c/way and one on the other. The c/reserve works are likely to be constructing new crossovers, or stripping down CRSF on existing ones
When large schemes like this go ahead you put all the traffic into one lane approx. 400m prior to what will be the proper taper position through to what will be the end of the works. This enables tapers, "return walls", contramark studs to be placed in greater safety. At the end of the placement of these items you remove this temporary closure to leave the proper closure.
Ah, that will explain why there is a wall of cones within the coned off hard shoulder. I had always presumed that rolling road blocks were the only way these things take place.
I don't know the answer to the VMS question
I ask because if you look at photo two you'll see that within that small space there's two VMSs and a bridge. If they don't move any of them the hard shoulder will drop so much they may may as well not bother building it.
There seems to be enough room within the current highway boundary, they may have purchased more land, or they may pinch some of the c/reserve
Yeah, now I look at it again it you're probably right. I doubt any more land has been purchased.
Schemes are dropped and resurrected at will (including this one), if those works weren't done it could be ages before you get the monies for it. Grab the chance when you can! For example, if people had held of doing schemes because a bigger one was in the offing, nothing would have been done on the A27 from the M27 to A3(M) since 1988
Fair enough, but given that the date of the start of the roadworks has been definite for a while now (the cones went out a few months ago) it wouldn't have hurt to wait a few weeks.
Ref Picture 8, I don't like the way traffic joins the main c/way. As the traffic joins it is heading to the offside just as traffic on the main c/way is being pushed to the nearside. I would prefer the traffic on the main c/way remained to the offside till at least 200m beyond this merge, then push it all to the nearside
I'm sure there must have been a better way of doing it. For a start, you've brought a very busy sliproad down to one lane and given the vehicles on it practically no space to merge. This morning I passed through the Delme Roundabout and both it and the eastbound flyover were pretty much solid. Although I can't be sure, I've got a pretty good idea that it was this merge that was causing it.
Also, if the sliproad is only single-lane, have lanes been coned off on the roundabout and the approach or is there space for a quick 'merge in turn' at the top of the sliproad?
