Firts bridge was built in 1963 and carried both carriageways:

At the same time they added the railway bridge carrying the high speed link from London to the Channel Tunnel:

Is there any reason why the A2 from Rochester to Dartford isn't considered motorway when clearly it all conforms to motorway standards? It seems crazy to me that cyclists can legally ride along that route.

What are these 'motorway standards' you speak of?

Put simply, the A2 isn't considered motorway because it isn't a Special Road that only allows Class I and II traffic - legal status is the issue, not alignment or cross-section. There's a big obstacle in that there is not a full parallel road for non-motorway traffic that would allow the right of way along the A2 to be extinguished. The upgrade alongside HS1 (that moved it off the original Roman alignment south of Gravesend) happened at a time when 'motorway' was considered very politically incorrect and so blue signs were unthinkable.

This is from the same school of 'craziness' as country lanes being 60mph limit, while A roads through the same are 50mph. What legally permitted is not necessarily sensible, and that's fine. The problem is when people forget that and think that as it isn't prohibited, it must be fine to do.

So what is the legal status of the A1(M) parts which seem not to have parallel routes?

And this is the main (if not the only) reason why it is still an "A" road and not a motorway. I don't buy the argument about lack of alternative route. That might be true about the Dartford crossing where there is no alternative for many miles. Here there are local roads which non-motorway traffic could take (A226 for example).

The legal status of all the A1(M) is "motorway", unsurprisingly.

Alternate routes exist to every enclosed space (eg via a track), and so the right-of-way along the A1 could be removed after online upgrades without the legal faff that that would require.

You are thinking macro, not micro scale. The rules about rights of way are micro. The problem is M25 to Ebbsfleet, AFAICS.

Traffic Lights to be installed on a MOTORWAY!

http://www.bbc.com/news/uk-england-manchester-41967961

Quote:
Traffic lights are to be placed on two busy link roads between the M6 and the eastbound M62 under plans to ease motorway congestion.
Testing has begun on the system, near Warrington in Cheshire, and it will be turned on fully in December, according to Highways England.
A spokesman said if the £7m trial was successful, it could be rolled out on motorway link roads across the country.
I suppose that if you have a very low entry level for what defines 'success' then it might be.

They mean Junction 21a of the M6 which is here.

Not news as there's rather a few locations where this is happened!

I believe this is unique globally, having ramp-metering on a free-flowing junction.

Ramp metering is fairly common globally where mainlines are clogged and you need to control traffic entering the motorway to not overload it in liue of spending money on upgrading the motorway. The initial UK trial scheme in South Hampshire was a failure that made things worse on the local network and dumped as soon as they could. The scheme in the Black Country is still sometimes operational (I think - the signals are still there), but they had to upgrade the mainline anyway. I don't believe there's been a successful implementation of ramp-metering in the UK yet. What we have is various different HE Areas looking at how other countries have addressed similar problems, but not at other parts of the UK and how that solution has worked there.

Examples in the US and the Netherlands are discussed on the previous page of this very thread, and Australia also has some planned.

Simulation of the A14 Cambridge to Huntingdon:



I think this is the most expensive (£1.5bn) road scheme currently under construction in the UK now the Queensferry Crossing is open.

Highways England have published a new document setting out their long mooted plans for expressways. The proposal is essentially to make them motorways, with blue signs and A(M) designations (which are already used for some motorways in the UK):



The upshot is that thousands of miles of grade-separated 4+ lane road is in line for eventual redesignation to motorway, bringing the abnormally low motorway mileage closer to normal European levels. Everything green on this map would eventually be blue:



The document states that the first newly designated expressway will be the A14 Cambridge to Huntingdon with other schemes (e.g. on the A303) also opening to expressway standards. It is not expressly stated that these will open with blue signs and A(M) designations though.

Roll out across existing roads seems more aspirational at this stage. The document sets out a four phase process:

Quote:
Phase 1: a 2-3 lane dual carriageway,
with no roundabouts, traffic lights or right
turns on the main carriageway, some
alternative provision for vulnerable road
users, such as cyclists, and slow moving
vehicles.

Phase 2: replacing central reservation
barriers with safer, rigid concrete barriers
for these high flow A-road sections.

Phase 3: introduction of technology and
operational changes, including Traffic
Officer patrol and emergency areas.
A scheme may designate as a motorway
and prohibit vulnerable road users and
slow-moving vehicles if appropriate
alternative provision is available, and
there are appropriate terminal points.

Phase 4: motorway designation of the
complete corridor.

3 questions!

Wat is APTR?

Will this affect Scotland too (A9(M), A90(M) etc..?

How is the dualling of the A9 going?

Thanks!

All Purpose Trunk Road, i.e. a nationally operated strategic route that isn't under motorway regulations or similar restrictions.

Highways England don't have jurisdiction over Scottish roads. I wouldn't be surprised if Transport Scotland responded with a similar initiative, incorporating similar standards, as they have for smart motorways.

Dualling on the A9 Kincraig to Dalraddy is complete. Ten other sections are in preparation: https://www.transport.gov.scot/proje...-to-inverness/

M62 Manchester

Extra lanes to open before Christmas on Manchester smart motorway

Drivers will be able to use over ten miles of extra lanes on the M62 near Rochdale in time for Christmas.

Highways England is opening a permanent fourth lane in each direction between junctions 18 and 20 of the M62 as part of a phased opening of the Manchester smart motorway scheme – increasing capacity on one of England’s busiest stretches of motorway by a third.

Roadworks will be removed from the eastbound carriageway tonight (Monday 18 December 2017) and from the westbound carriageway tomorrow night (Tuesday 19 December 2017).

Construction work will continue between junctions 10 and 18 on the M60 in 2018 to complete the installation of over 350 electronic signs, over 100 traffic sensors and 50 CCTV cameras.

Resurfacing work will also take place along the entire smart motorway route using overnight carriageway closures. The project is due to be completed by summer 2018.

The full scheme stretches 17 miles between junction 8 of the M60 near Sale and junction 20 of the M62 near Rochdale.

Except they are NOT motorways as they are not built to the required standard.

By all means upgrade them properly, but otherwise don't call them what they are not.

Motorway is a legal term, not a standards term.

All expressways will be dual carriageway, unlike Exhibit A, Exhibit B or Exhibit C

With central barriers (and of a higher standard than required on motorways if the proposal becomes the end product), unlike Exhibit D

And no roundabouts in the middle, unlike Exhibit E.

That they don't have hard shoulders is like every single current Smart Motorway (seen as better than regular motorway) in the country.
