It's the right hand "Y" branch that's under threat, currently.

Under threat in what sense? HS2 Phase 2a completed its parliamentary
stages almost two years ago, and is now the High Speed Rail (West Midlands
– Crewe) Act 2021. It will be constructed concurrently with Phase 1, and is
due to open only a year later.

OK, yes, that's not yet completed its parliamentary stages, though the

That phase won’t need serious spending for quite a few years, so it can
safely stay in the plan for now. Some future government can collect the
opprobrium if they choose to trim the plan in the years to come.

Because the contractor will will take the cheapest option for the work
which generally will be to close the motorway for a long as possible.
Conversely the regulator doesn't examine the work plans to ensure the
work is being done as rapidly as possible.

The regulator is the ORR!

Some friends drove through there on Tuesday and their journey took about
two hours longer than usual. When we have road charging those
responsible for closures should pay compensation to each person for the
delays.

You are aware that such road works involve "hiring" the appropriate
section of road for the duration of the works with penalties if the time
is exceeded?

<mode = speculation>

Looking at the video, it appeared (to me) that there had been quite a
bit of work done on the surface of the road either side of the bridge
site, in addition to the work needed to create the haul road for the
bridge, and that amount of plant won't appear on site in a matter of
minutes (I know, some of it could have been parked up along side in
readiness). Once all that has been done, and the new bridge is in
place, there will be a lot of tidying up to do afterwards. Still 10
days does seem a bit long. The plan would make for interesting viewing.

Thanks, it's interesting how they completely revised the design and
construction plan, mainly to reduce motorway traffic disruption:

The original HS2 Environmental Statement (ES) scheme design required the
bridge to be constructed ‘in situ’ on a live motorway over a 20-month
period. This option would require three months of total overnight closures,
narrow lanes and a reduced speed limit of 50mph to complete the works.
These lengthy closure periods would require a defined diversion route to be
active for a three month period increasing traffic volumes, congestion and
delays on the local road network.

We reviewed and developed the original design, focussing on reducing the
impact on road users and improving safety for our workforce. This has
resulted in a fundamental change to the construction method with the box
structure now constructed to the side of the motorway and then pushed into
place using a ‘box jacking’ technique, rather than being constructed in
place.

Design and construction benefits

A range of benefits will be achieved through the current design and
construction method:
• Using the ‘box jacking’ technique to build the box structure means
installation over the motorway
will be carried out during the temporary closure. Building it in place
would have required 18
months of traffic disruption.

• A reduction in night time disruption for local residents as the new
construction period will avoid
the need for prolonged periods of night working.

• The updated box structure design is smaller in size and will therefore
have a reduced visual
impact.

• A reduced impact on the flow of groundwater following a change to the
foundations for the box
structure.

Very few: they'll all have used the A4091 + B5404 or A51 + Trinity Road,
which are both much shorter than any signposted diversion.

Because they can? There's a definite trend for "road works" to close a
road for anything from 3-12 weeks, during which there's only something
actually happening less than a quarter of the time.

The latest set near me it took them a week to come and remove the "Road
closed" signs after all the actual civil engineering had been completed.

curves to keep speeds high.

Keeps it out of sight of the nimbys

Yes, it was a very expensive way of buying off some of the NIMBYs. But I
bet a lot of them still opposed it.

We've come a long way since The Brunels and their tunneling shield.

No tunnels in this crossing.

Sure, HS2 will have lots of bored tunnels, but this story isn't about any
of them.

So much of HS2 will be in tunnels that I suspect it's likely to be a
contender for worst British railway journeys.

But does it need to be? Modern high powered elecrics won't lose speed
going up hills - which was the French approach with their TGVs. Avoid
curves to keep speeds high.

Oh yes. As a former member I've learnt from residents' association
members here that they oppose almost everything on principal and don't
care who they tread on or use to achieve their objectives. In short
they're bullies.

Up to three of them have received "words of advice" over the past 36
hours which shows how dirty they are prepared to fight.

As luck would have it, when I was moored at Curdworth next to the HS2
site earlier in the year I engaged another boater in conversation, and
they declared they were vehemently opposed to HS2, because as a resident
in the Chilterns there wasn't a station for them. This despite the
millions spent tunneling in the Chilterns to appease the NIMBYs, so they
shouldn't even notice it's there.

Yes, that money was effectively wasted. Dame Cheryl Gillan vehemently
opposed HS2 till her dying day. In the subsequent by-election there was
nevertheless a huge swing against the Tories, who lost one of their safest
seats.

The rub being many of them will be dead by the time it is finished like
that actor Geoffrey Palmer who made a career of playing a gormless twit in
many sit coms who became a figurehead for the NIMBYS .

IIRC the principle of TGVs is actually rather more like a roller coaster -
they don't (and indeed can't) maintain full speed up and over the hills.

Sadly, yes. There will even be a lot of shallow cut and cover tunnels just
to hide it from view (and to ruin the views from the trains).

We've come a long way since The Brunels and their tunneling shield.

OTOH the main spans of both the Britannia Bridge in North Wales and the
Tamar Bridge in the South West of England designed by Robert Stephenson and
Isambard Brunel respectively were both fabricated on a site adjacent to
their final position and then moved on pontoons to the pier locations from
which they were jacked up as the pier construction followed.
