Re: Highway Plans SABRE Maps layer
Another map has gone up from Truvelo's pen.
This time it's the M4 Newport Southern Bypass from 2018.

That junction at Magor looks even sillier in neatly drawn form.Steven wrote: ↑Sat Oct 28, 2023 20:57 Another map has gone up from Truvelo's pen.

And I thought it was policy not to build junctions with an exit slip for which there is no equivalent onslip for the opposite direction.Bryn666 wrote: ↑Thu Nov 02, 2023 16:00That junction at Magor looks even sillier in neatly drawn form.Steven wrote: ↑Sat Oct 28, 2023 20:57 Another map has gone up from Truvelo's pen.

Limited access junctions aren't forbidden, but they are discouraged where they could cause navigational and network usability issues.Truvelo wrote: ↑Thu Nov 02, 2023 19:18And I thought it was policy not to build junctions with an exit slip for which there is no equivalent onslip for the opposite direction.Bryn666 wrote: ↑Thu Nov 02, 2023 16:00That junction at Magor looks even sillier in neatly drawn form.Steven wrote: ↑Sat Oct 28, 2023 20:57 Another map has gone up from Truvelo's pen.

Re: Highway Plans SABRE Maps layer
I can’t really see why there wouldn’t be a corresponding westbound on-slip - there’s an existing road crossing the motorway so a sliproad could have linked to that. It’s very odd.

Re: Highway Plans SABRE Maps layer
That slip road was a last minute addition. The earlier plans didn't have it.

Re: Highway Plans SABRE Maps layer
I'd assume it's because the offslip fits in easily between the new M4 and realigned A4810 and links into a junction required anyway, while an onslip would require purchasing of extra land east of the roads and a new roundabout to be built.
The space might also be land earmarked as housing development given its proximity to the edge of Magor.

Thanks to the research skills of Truvelo, he's allowed us to bring to SABRE Maps another of the unrealised plans from the archive.

Re: Highway Plans SABRE Maps layer
Indeed... This one I'd have thought would be something of a no brainer, especially given satnavs direct you that way anyway and along kelsterton lane when traffic is bad on the 494 through astonBryn666 wrote: ↑Sun Feb 04, 2024 22:59Surprisingly less new road needed to make that happen than I had thought!Steven wrote: ↑Wed Jan 31, 2024 08:23 Thanks to the research skills of Truvelo, he's allowed us to bring to SABRE Maps another of the unrealised plans from the archive.

It would have made the upgrading of the A494 south of Shotwick 15 years ago to full D3M standard redundant.

Re: Highway Plans SABRE Maps layer
The A494 is a classic example of "do it all or don't bother". A longer length of the widened bit has been painted back down to 2 lanes because the lane drop was causing more problems than it solved being right at a merge point with a slip road as well. The lane drop is now before the A548 GSJ.

Re: Highway Plans SABRE Maps layer
That seems to be the case where long sections of road are upgraded such as the smartification of the M1 and M6 which were done in separate sections. As for the A494 I wasn't aware it had been hatched down to two lanes but the latest GSV shows it was done last summer. It also shows this section which is wide enough for six lanes now only has one third of the carriageway in use. The rest of the asphalt is now sitting idle.
