Towns with an HQDC through the middle

[GC_NEMan1]

Is the A690 through Houghton-le-Spring NSL? That always seemed a fairly brutal bit of road building.

No, there's a 50 limit on that road.

[JosephA22]

If counting motorways as HQDC, then the A1(M) west of Doncaster could count. It scythes through Warmsworth with housing right up against both sides of motorway.

A14 through Bury St Edmunds. Certainly goes through the town and qualifies as HQDC but I think it has a below-NSL limit these days.

A47 at Dereham, though part of it is single carriageway

[Big L]

A14 through Bury St Edmunds. Certainly goes through the town and qualifies as HQDC but I think it has a below-NSL limit these days.

I don’t recall a lower limit when I last passed that way (end of October), which is why I nominated Bury somewhere upthread.

If HQDC can mean no central gaps and restricted to motorised traffic only, and "middle" being 700 metres from City Hall, then the Westlink Belfast

The only side of the planned "Belfast Urban Motorway" inner ring that was built, the conspiracy being that it acted as a bit of a "peace line" being a literal trench - https://scopeni.nicva.org/article/if-pe ... s-had-ears

Until recently the A470 hammered through the centre of Pontypridd at 70mph, but is now subject to a 50mph limit. All the junctions are GSJ'd

What about Hatfield - a fair amount of the town lies to the west of the A1(M).

The A1(M) s goes through the tunnel, the old A1 route which ran past the airfield which is to the west of it. Most of the town is to the east of both of them although urban sprawl is heading west.

The original 'Old' Hatfield near Hatfield House and the post war New Town lie wholly to the east of the A1(M) and what is now the A414. The residential parts that lie to the west are in 3 sections - Hatfield Garden Village to the north, the redevelopment of the former Hawker-Siddeley/BAe site (which is also commercial) in the middle and the former village of Ellenbrook that lies just south of the St Albans Road (A1057).

Also ruled out as it’s a motorway! The title states HQDC…..

Oops - yes. Now I think about it I think it had a temporary 50 or 60 that applied for a long period so maybe I was thinking of that.

[NICK 647063]

The A64 Ring Road section that used to be a multiplex with the A6120 is a 70mph HQDC, it passes between the houses in Seacroft East Leeds, it’s just under a mile between roundabouts but gets some serious speed, ironically it’s far safer than the A64 each side of it that’s 40mph, this is because pedestrians are catered for via a footbridge and subway and has no traffic signals, although its reduction to 40mph is within the next year or so…….

In what way is a grade separated dual carriageway with a 70mph limit not high quality?

[XC70]

A61 through Chesterfield. Partly 50 and partly 70.

[Owain]

A40 Monmouth has traffic signals at the Chepstow bridge if I'm not mistaken ?

Correct. And it also has a roundabout where eastbound traffic on the A40 wanting to turn right onto the A466 at the traffic lights has to pass this junction where no right turns are allowed to then turn and approach the junction and turn left whilst heading west.

It's also subject to a 50 limit, although I can remember when it wasn't.

The A465 at Neath could be a contender...

Well there is this one for a start - the A1 at Great Ponton

Doesn’t look especially grade separated there.

[Vierwielen]

Does the A331 count? Although it does not split any towns int two, it does split the Frimley-Farnborough-Mytchett-Ash-Aldershot-Ash Vale conurbation into two. Some of these towns are in HAmpshire, others are in Surrey and between its roundabout where it links to the M3 and its roundabout where it terminates and joins the A31 it more or less follows the Hampshire-Surrey border.

[tom66]

Could be argued that the A45 somewhat bisects Northampton too. It has a short section of 60mph lower quality urban expressway type road in the middle (between Barnes Meadow Interchange and Queen Eleanor Interchange) but most of it is decent and 70mph is safe and legal.

[jnty]

The M/A27 has to be a contender at some point between Southampton and Havant.

The M3 at Eastleigh?
