Trumpety trumpets
The double trumpet is quite a common interchange in many countries, especially when one road is a tolled motorway as it only requires one set of toll booths and two bridges to give freeflow interchange between the two roads.
I think this complex in Portugal wins the contest of the most trumpets in one area: four and a half, although one isn't yet in use.
Can anyone find more trumpets in one junction complex?

Re: Trumpety trumpets
It looks like the typical sort of mess when new roads have been added piecemeal over the years.
How would you like your grade separations, Sir?

Re: Trumpety trumpets
I had a look at the junction on google earth only a week ago when measuring the E 01 (I was really bored).
I did spend a while trying to work out what all the movements were, and why a seemingly low traffic IP was getting a whole new motorway, but I guess that's just how they do thing on the continent.

Re: Trumpety trumpets
If even the Portuguese think the traffic volumes are too low for a motorway then it really will be deserted. Some of their motorway sections have 10000 vehicles per day and as a result are very nice to drive on!M4 Cardiff wrote: ↑Thu Sep 03, 2020 22:40 Interesting story behind why the A26 was never finished https://translate.google.com/translate? ... toestrada)
Re: Trumpety trumpets
We came close to getting one in 1995 if you count the one at the top of the map as a trumpet bolted onto an existing one.

Re: Trumpety trumpets
How and why did that junction end up with such a strange layout? I assume there was some kind of constraint preventing construction of a more regular design. Same really for Bullington Cross.

Re: Trumpety trumpets
The northwest side of the junction is hilly which would require a very deep cutting and there's also a group of houses. However, it's one junction where the obvious solution is to build a trumpet at the other end of the slip road like those on toll roads.M4 Cardiff wrote: ↑Sun Sep 06, 2020 18:15 How and why did that junction end up with such a strange layout?

Re: Trumpety trumpets
Seems a reasonable way to connect a one way loop around the terminal to two parallel roads.

Re: Trumpety trumpets
Bullington Cross - and the Sutton Scotney bypass - was in my area in 1981. The main over bridge, carrying the A303 east-west above the North-South A34, was developed offline to the west, to align better with the new Sutton Scotney (and Worthy Down) bypass which ran further west than the original alignment.M4 Cardiff wrote: ↑Sun Sep 06, 2020 18:15How and why did that junction end up with such a strange layout?

I do agree the layout is suboptimal given current traffic on the "M34". Hurtling northbound on the A34, many drivers instinctively move right as we enter the "dip" under the A303. The on-ramp northbound really should be a crawler lane to the top of the hill - and this is a piece of the A34 that only celebrates its 40th birthday in the next year or so.

The title of this discussion gave me a fright! Initially I thought that it might have something to do with the US election.
