As I understand it the plans mostly involve junction improvements, with no improvement to the road in between, which really is where the problem lies, more so than the junctions. Find a way of increasing capacity first then deal with the junctions. Or just bypass the whole lot and solve it that way!

The current road could only be improved if one junction, and maybe two sets of lights were removed. And have at least 2+1 (for westbound traffic).

Otherwise, nothing else than a GS D2 will do.
Sometimes, spending millions of pounds on a solution can actually make matters worse. After all, there would be a period of very disruptive roadworks while the so called "improvements" take place, and even when the works are completed, the new road layout can create new pinch points.

There are two crossroads, too close to each other. Of course, these are both signalised. They don't also appear to be linked, so it's quite possible for the second set to be on red when the first lot have gone green.

The result is that traffic backs up on the first NSL section since Shoreham airfield lights. Traffic creeps past the first set of lights, unable to go any further. So the queues lengthen, and lengthen...

I would say the second junction should be closed, or made LILO-only, as an interim measure. The sheer size of the queues means that traffic becomes dense very quickly indeed.

It would be hideous but since every other option has setbacks, why not consider building a new A27 on top of the old one?

It would be easier to engineer than the common suggestion of a double-deck motorway because there are no GSJs. The new road could be slightly wider as there would be no footways, while any footbridges could be replaced by at-grade crossings along the quieter old road.

The section past the cemetery would be difficult to align but it doesn't need to be perfectly online.

Wouldn't that immediately be turned down on amenity grounds - because it would look hideous and block everyone's light??

There is pretty much residential property on all sides - you could only do this if everyone was compulsorily purchased - which would also mean you could build a bog standard D2 for a much lower cost.

No, I think the old plans need to be reheated again. Yes, it meant some demolition, but at least it was trying to keep the A27 on a consistent axis in the north of town, which it currently doesn't. Making a beeline instead for a useless multiplex along Warren Road and the A24, and Crockhurst Hill roundabout, before crawling up past the cemetery. It's just about one of the most difficult online routes you could ever hope to upgrade.

Or did I misread that completely, you meant to rebuild the A27 as an online upgrade?? :?

'Transport Secretary calls for review of alternative A27 options for Worthing and Lancing' (http://www.worthingherald.co.uk/news/po ... -1-8193496).

Specifically he says 'I will instruct Highways England to provide me with a review of the viable alternative options considered as part of the feasibility study in 2014, including a grade separated option'.

Perhaps the mention of 'a grade separated option' (singular) refers to the 'hybrid' option, which from the exhibition panels seems to have been the only option with grade separation that wasn't discarded early.
Option - Type of carriageway - Junction Design - Access to properties and side roads - Cost Range
Option 2 - Single - Flyovers and underpasses - Maintained - Discarded early as well in excess of the upper budget
Option 3 - Dual - Junction improvements (no flyovers or underpasses) - Maintained - Up to £274 million
Option 3A - Dual (narrow) - Junction improvements (no flyovers or underpasses) - Maintained - Up to £238 million
Option 4 - Dual - Flyovers and underpasses - Maintained - Discarded early as well in excess of the upper budget.
Option 5 - Dual - Flyovers and underpasses - Maintained via service roads to key junctions - Discarded early as well in excess of the upper budget.
Hybrid - Dual - Combination of flyovers and underpasses and junction improvements - Maintained - £250 million to £350 million

There has been some local interest in tunnelling and a new northern ‘bypass’
route, but these have also been discounted:
Tunnelling: would cost £1.2 to £1.4 billion and provide poor value for money
Northern ‘bypass’ (A280 Long Furlong, A27 and A283 Steyning Road
/ Washington Road): the route is within the South Downs National
Park, which is protected. Also it would cost considerably more that the
economic benefits gained.

Seems the proposed scheme may be on hold following review of more ambitious alternatives.

The locals still seem to believe a northern bypass is a viable option, which it isn’t. Also, where did the local paper get a figure of £69m for the total cost of the improvements?? We all know you won’t get much done for that.

At no point does the M6 route through a National Park - in fact the recent extensions of the Lake District and Yorkshire Dales National Parks explicitly excluded the M6 corridor, and the M6 acting as the boundary - and is why the YDNP extends into Cumbria, rather than the LDNP extending further east

Not quite correct. It is just inside the LDNP for about 1km near Thrimby, about 5 miles south of Penrith, where the nearby A6 is the park boundary.

This part is correct.

You know, the more you consider it, the more it makes sense. At least through the crowded, congested parts of town.

No-one can complain about noise, traffic, or pollution - because they already exist, and would probably be reduced (apart from traffic using the A27). And towns like Middlesbrough already have elevated highways. The only complaints would really be about visual intrusion.

If you travel along the A270 Old Shoreham Road, there’s a section where the main carriageway is slightly sunken. And I think that is very similar to Worthing too. A double-deck highway would be ideal.

These "improvements" may now be paused...

https://www.worthingherald.co.uk/news/p ... -1-8699294

Obviously a northern bypass is a non-starter, perhaps Highways England will re-consider online widening to S4 or D2 But the locals won't like that either!

I think you could do narrow lanes D2 within the existing boundary - you’d just need to provide new kerbs and pavements. But something has to be done about those junctions...

Another new roundabout will appear in Lancing in the next few years as a new IKEA and a housing development is being put in between Brighton Airport and Lancing on some rather moist ground (some could call it a floodplain).
https://www.theargus.co.uk/news/1826329 ... -next-a27/
The planning application which has been on-going in its current form for three years was approved earlier this month and includes a new roundabout, and a lot more traffic for the A27.
On the plus side, a condition is that they are going to remove the traffic light controlled crossroads (where the Hawker Hunter crashed during Shoreham Airshow in 2015), they are going to leave the northern side as a LILO built to 120kmh standards, while the southern road (which leads to an industrial estate and permiater road for the airport) will be diverted to connect into the new development.
Another thing to note is that another condition is that they are going to have to do some works at the Manor Road Roundabout. These works are basically widen the approaches to three lanes (from 2) in all directions. It is to note that as part of HE's "Worthing & Lancing Improvements" they were going to turn this roundabout into some crazy double t-junction weave into itself, so I assume this is a little bit more confirmation that HE are not serious about doing anything themselves at Worthing & Lancing and instead may just be waiting for RIS2 for funding for a proper solution for the A27 through Worthing & Lancing.

Think I prefer the HE's plan as this would have improved the free flow of the A27. Still surprised the HE withdrew there objection to an IKEA, massive traffic generator on a very congested piece of work.

Very moist ground is an understatement and I was at the Adur Local Plan examination, three years ago. The water table is very high as it is affected by coastal flooding as well. On high tides the River Adur, becomes so high, that it seeps into the groundwater, pushing the water table up, thus the saltmarshes and former salt mines on the land of the development.

Development will only be permitted if mitigation to this problem is found, which could be difficult. The number of drainage ditches are clear on google

Glad the Sussex Pad signals are going, think they are lethal especially coming from the east, a HQDC, with three lanes just shortly before ending at a set of signals. Always thought ending at a roundabout was better, the original Shoreham bypass.

Out of interest, is this hopelessly optimistic (in the same way that Lydd Airport fancied itself as 'London Ashford' for a while), or has Shoreham aerodrome been renamed in an attempt to distance itself from the Hunter crash?

The current owners who bought it in the mid-00ies (horrible phrase) renamed it "Brighton City Airport."
