Re: Towns with an HQDC through the middle
A48 in Cardiff is dualled and fully grade-separated from the A48(M) to the A470. The limit used to be NSL too, but I don't know if it still is...
(Maybe it's now 20? ).

Re: Towns with an HQDC through the middle
It's not NSL (and 50 is quite justified due to the substandard width), but the A12 Gorleston-on-Sea throughpass is quite a distinctive one as it only opened in the 1990s. It's got a GSJ and several bridges, and used a disused railway alignment.
Another could-have-been one that was more recent than most was the alternative option for the A12 at Chelmsford, which would have seen the inner bypass upgraded to expressway standard.

Re: Towns with an HQDC through the middle
Don't joke! . Streetview (Aug 23) suggests a mixture of 40 mph and 50 mph now with an asymmetrical limit at some points.

Re: Towns with an HQDC through the middle
Because it’s a motorway not a dual carriageway! The topic would state Motorway not HQDC in title if that’s what examples were required.trickstat wrote: ↑Tue Apr 23, 2024 18:46In what way is a grade separated dual carriageway with a 70mph limit not high quality?NICK 647063 wrote: ↑Tue Apr 23, 2024 15:55Also ruled out as it’s a motorway!

Re: Towns with an HQDC through the middle
In that case I'll consider myself privileged that I was able to enjoy it in the NSL days.multiraider2 wrote: ↑Wed Apr 24, 2024 17:46Don't joke! . Streetview (Aug 23) suggests a mixture of 40 mph and 50 mph now with an asymmetrical limit at some points.
I remember my dad telling me that he drove on the A48/A470 GSJ on the day that it opened...
Re: Towns with an HQDC through the middle
It has 3 lanes northbound and 3 lanes southbound and a central reservation which means it is a dual carriageway. Yes, it is also a motorway in the same way most other examples in this thread are also A roads.NICK 647063 wrote: ↑Wed Apr 24, 2024 18:45Because it’s a motorway not a dual carriageway!

Re: Towns with an HQDC through the middle
To be clear the OP asked for towns with “a main through route dividing them, no roundabouts or signals, no speed restrictions, nothing”. The original example given was an all purpose road, but I don’t see anything there that excludes motorways.trickstat wrote: ↑Wed Apr 24, 2024 20:47It has 3 lanes northbound and 3 lanes southbound and a central reservation which means it is a dual carriageway.

Re: Towns with an HQDC through the middle
Also, lets not forget, "Motorway" is a legal, rather than engineering term. There's plenty of non HQDC Motorways out there!
Built for comfort, not speed.
Re: Towns with an HQDC through the middle
I'm fine with motorways being included
Did we get M60 at Stockport ?

Re: Towns with an HQDC through the middle
The OP went further: "In the USA this is nothing unusual to have freeways going through places, ...". As far as I am aware, the differences between an American "freeway" and a British "motorway" is minimal and probably varies from state to state.Chris5156 wrote: ↑Thu Apr 25, 2024 09:08To be clear the OP asked for towns with “a main through route dividing them, no roundabouts or signals, no speed restrictions, nothing”.

Re: Towns with an HQDC through the middle
What about London, sort of e.g. A102/Blackwall Tunnel/A12 (I know there’s a bit of at-gradery on the north side, and it’s not quite through the middle…).

Re: Towns with an HQDC through the middle
It's HQDC like the A406 North Circular in parts but is subjected to 40 / 50 mpg restrictions. None of it is 70mphroadtester wrote: ↑Thu Apr 25, 2024 13:34 What about London, sort of e.g. A102/Blackwall Tunnel/A12 (I know there’s a bit of at-gradery on the north side, and it’s not quite through the middle…).

Re: Towns with an HQDC through the middle
If we are accepting motorways then the M54 goes straight through the middle of Telford, while the the A38 goes straight through Burton-upon Trent at 70mph and further north bisects Alfreton in two also at 70mph

Re: Towns with an HQDC through the middle
That's an odd one, to start with despite being decent quality D2 just south of Washington for much of the route its S2 and its non primary !
From Washington it heads SE to Easington, from there it multiplexes with the A19 heading north to Murton before heading NE to Seaham along what is basically S2 with climbing lanes, really that section should have a separate number. The road varies in quality so I don't see it as HQDC
Here it is at the bottom end of the scale.

Re: Towns with an HQDC through the middle
The OP never specified that that the road had to be a HQDC along its entire length!KeithW wrote: ↑Thu Apr 25, 2024 14:13That's an odd one, to start with despite being decent quality D2 just south of Washington for much of the route its S2 and its non primary !

(Also I could have mentioned A1231 Sunderland Highway: I only picked the A182 because it has the flyover where it meets the A1231.)
Re: Towns with an HQDC through the middle
Indeed but I expected to find more than 4 miles of D2. The reality is that the New Town and the new A182 came into being about the same time, note the nice HQDC peters out here. Not that I class it as HQDC as there are 4 roundabouts in those 4 miles. More like Milton Keynes in fact than the A1(M).

A66 through Boro is pretty high quality, it is before you hit the junction at the Evans Halshaw anyway

Re: Towns with an HQDC through the middle
While motorways are a designation rather than a standard of road, motorways have certain requirements such as emergency phones and provision to get broken down vehicles off the carriageway.trickstat wrote: ↑Wed Apr 24, 2024 20:47It has 3 lanes northbound and 3 lanes southbound and a central reservation which means it is a dual carriageway.

The question given is specifically about HQDC, which is a particular engineering standard and does not refer to motorways. In NI, it’s a type 6 DC which means 1m hard strips, no central reservation gaps, continuous median barrier, and all junctions LILO, some form of GSJ including compact or roundabout.
If motorways had been intended, it would surely have been in the first post or the subject title.
Re: Towns with an HQDC through the middle
The A66 east of the Cargo Fleet Roundabout was built by the council rather than Highways England/the Highways Agency as I recall, the council funded the through about as I recall.
