I'd like to see both, something like this:

For weaving reasons you'd have to close the westbound offslip at the next junction west.

That is to say, although only the deck and road surface is visible the side walls of the future underpass must be present all the way down to below the underpass level, but invisible at this stage. So there's sort of more completed infrastructure than you can actually see?
I don't know the details of the method used in this case but a method sometimes used is to drive or bore rows of piles to form the abutments, then put the deck on, then excavate the earth away, then put some sort of facing on the abutments. Given the difficult site that may be what they've done here. It's difficult to see while trying to drive.

Did some more searching and it's HE that use the term 'top down' in their description of the scheme. Perhaps it will possibly look similar to the way the M4 underpass at Chievely ended up. The lower levels of the piled walls alongside the carriageway there have an 'architectural' facing applied, but the higher levels seem to be just rough concrete, possibly a sprayed finish.

So after these improvements are done, it looks like they'll actually be getting some grade-separation done at the A19/A184 junction.

I haven't used the road anytime recently, but I've never seen why the freeflow has to end so abruptly in a fairly random location.

Ideally, the A168/A19 would be wholly freeflow from Dishforth to Seaton Burn.

It does seem that - eventually - that may be the case - although it's also fair to say that traffic has thinned sufficiently that by the time you get to Moor Farm roundabout, it's rarely an issue.

Just thought I'd provide a link to this chap's drone coverage of the worksite, found it via the Newcastle section of skyscrapercity:

Hope it is of interest.

A19 to A19 is a must. I'm not sure what the A189 to the south of Moor Farm is like as I've not really used it when I've been up that way but grade separating the Spine Road section to the north would be a benefit as that always seems to be busy until you pass Blyth.

I've been watching the old Likely Lads film, where Terry lived in a block of flats near the junction, and noticing how quiet it was. Back then, where the Silverlink is now, was fields, and the only building near the junction was the Europa Lodge Hotel, and some old timers still refer to the junction as The Europa Lodge Roundabout.

I remember going that way to the caravan which was in Ellington. We would go across the Tyne Bridge then pick up the coast road to the (then) A1 and up to the spine road A189 up to Ellington. Much of it was still single carriageway.

Due to the installation of concrete beams, the A1058 Coast Roas will be closed between December 1st and December 4th.

This is the Norham Rd junction, where a new four lane bridge is being built over the A1058 to replace the massively congested two lane bridge.
You had me wondering then if it was the A1058/A19 junction as this would have meant traffic having to come off the A1058 and via the A186 and A193 through Wallsend and North Shields, with gridlock of an M25 variety.

Apologies if I had anyone confused there.

I posted that here because its relevant to the A1058 in general, rather than specifically these works.

Here are a few of the more interesting rejected options:

3b - Copy.PNG
4c - Copy.PNG
Terrible render for the last one, but it's a stackabout with some freeflow left turns and a freeflow loop, similar to M62 J6.

The parclo in the first rejected option looks impressive at first glance but delve deeper and its limitations are clear. There are no right turns from A1058 to A19. All north facing A19 slips have to use the roundabout to the north.
How would you like your grade separations, Sir?

The funny thing is that a one loop design with even worse connectivity stayed in the design process for longer, and they prepared several versions, e.g.:
1c - Copy.PNG
1d - Copy.PNG
I also found the turn count data:

All through traffic on the A1058 is now using the eastbound carriageway, including the new eastbound half-bridge over the future A19. It may have been like that for quite a while, but today was my first visit since the autumn.

The half-bridge is wide enough to carry four narrow lanes, even though the finished bridge will only be D2. (The bridges in the original Coast Road dualling, such as the bridges over the A19 roundabout, were designed for D3.)

In the nearby Norham Road bridge reconstruction over the A1058, the bridge is still closed but half the new superstructure is in place.

Aren't the new bridges going to be D3, but narrowed to D2 with hatching like the original bridges?
