They are all bad except for Chevening. I don't know why people think it's so bad. It's fully freeflow and although one key movement is missing and the M25 TOTSO's it's a brilliant piece of engineering. The queuing below is caused by a lack of capacity on the M25 rather than the junction itself.

M50 J3 is the worst, but most of those are pretty bad too.

Yes, but it's perfectly fine for the traffic levels it handles. Most of those on the list can't handle the traffic levels that use them.

Hermiston Gait.

The Queues aren't so bad on the M8, but its just so frustrating that they spent all that money on fancy flyovers for the A71, but the M8 ends at a trafic light controlled roundabout. Why not grade seperate it instead of wasting all the money. :roll:

Most of the queues on the bypass are nothing to do with the junction itself, but the lack of capacity on the bypass between Hermiston Gait and Lothianburn.

Catthorpe gets it for me, it's not the worst junction because it's busy, it's just terrible, not how major roads should meet.

It looks like at this moment catthorpe is the worst with 57% percent the poll only just started though and i thought Simister would be more known and more chosen since i uploaded 5 photos around that interchange...

however, as i promised this will go on for ages so anything can happen.

I presume your defenition of 'Worst Junction' is the same as CBRD. As others have pointed out some junctions are just overloaded (Tollbar) whereas some may be poor design but the low traffic levels don't justify altering them (M50 Jn3).

I could reel off a list of congested junctions but are they 'Bad Junctions'?

yeah i could say that really as i learnt about these junctions there but i also looked in my collins atlas and found the junction designs. i have not visited the bad junctions area recently but i know M8 J20 was not there. also i feel these junctions are badly designed

I think the big one is missing: M40 J10. J15 isn't that bad provided you get in the right lane and 'go with the flow', same with Tollbar. That doesn't mean they shouldn't be removed, though.

Out of the ones listed there, Catthorpe is the worst. M27 J3 and M50 J3 are both absolutely fine.

I used to be a local of this junction and would rather defend it than attacking it. Sadly they want to add extra slip roads to M26 and I'm partly against this due to the fact that Chevening Road may be demolished in the process which IMV is a very impressive road that provides a great view of the motorway as shown above. Plus travelling on the loop to the A21 can be pretty fun too.

I’d like to also nominate M6, Junction 15. The off and on-slip southbound aren’t that bad to be fair, but they’re ridiculously tight on the northbound carriageway and the on-slip is far too short given the speed you have to approach it from the tight loop.

Catthorpe is badly designed and one place where I wouldn’t want a Dumbell to be used. The lane drop between both roundabouts under the M1 really doesn’t help either. This junction certainly needs a complete redesign to increase free-flow.

M50 junction 3 also has to be amongst the worst. It may be acceptable for the traffic levels I agree, but this is barely acceptable for a busy dualled A road...

Looking at the ariel veiw there looks like a bit more space for the northbound slips or they could bulldoze M6 J15 and make a new GSJ with the road where the northbound exit leaves the M6. may need to put James irlams depot into consideration though...

Something like this?

The problem is that, IIRC, the gradient isn't all it seems in the aerial view so any decent GSJ would cost a lot of money.

Are north-facing slips even needed now we have the D-road?

sounds like a real good idea. i would kepp the north facing slips as without these a southbound journey would have 20+ miles without exiting (not including MSAs. you managed to not chop many trees down and saved james irlam as well.

20? I (or Google, actually) make it 9 miles!
