Dual Carriageway noise

Just out of interest, would triple glazing help? I would have thought this would have quite an impact. I get that you would need to keep these closed, but I would have thought that was more at the back of the house and leave the front open.

If the road is widened, say to 6 lanes, how will that "add value" to your house?  It will make it nosier and possibly closer.

Was also trying to figure out how the property will go up in value with more lanes or did I miss something?

Me too !  It is my biggest question, along with the repeated mention of "offline" which I have no idea as to what that means. And surely you have been out in the garden for many weekends during summers and not realised there is a massive road at your garden fence ?And if it's going to be worth £500,000 after works, what is it worth now before the roadworks ? And have the roadworks been given 100% approval that cannot be rescinded ? And I also don't understand the posts from people recommending triple glazing on that side of the house : they have failed to read that the O/P is only talking about noise in the garden as I understand it.
This is a "messy" thread and I find it a bit difficult to give any answer than those which must have occurred to the owners before they bought it in the first place.

Yes, I don't think triple glazing will work IN the garden, unless you can build a big wall with triple glazed windows around the garden! 

Think longer term and we'll all be in silent electric vehicles so you just need to put up with engine noise a while longer.

I did see one of those gardening programs on TV and they installed a water feature to mask road noise in one case, which may work?

The vast majority of the noise from a dual carriageway is the tyres so silent EVs won't be much better.

They're building the wider road next to the existing one, which will be retained as local-use-only.

It didnt work for the property i viewed

Triple glazing helps with road noise to a degree, but again it's not the most useful thing. The physics principles here basically tell you to:

a) insert as many different layers of substances between the source and the receiver as possible. Each transition between substances will reflect some of the energy, especially if they have different acoustic properties

b) again, high acoustic mass materials help - thin glass and gas isn't great in this regards unfortunately.

c) a surprisingly important one - different gaps between the surfaces. This is an area where standard triple glazing falls.

d) No gaps again! No trickle-vents, sturdy frames etc with proper sealing around them. Air brick in the subfloor even can be an issue. 

Proper acoustic windows are often triple-layered, but the construction is different to standard triple glazing. The gaps between the three sheets are not even. There is often a clear plastic-type laminate layer on or in the glass panels, to add more layers with different acoustic properties. The windows are held into the frame with vibration-deadening material.

In fact, people often report better noise reduction results from secondary glazing rather than standard triple glazing for the reasons above.
