The left lane is a bit too close to the barrier to me. No space to correct a mistake.

Other example with 7%, the A89 (previously A72) in France, between St Etienne et Clermont-Ferrand:

The A51 near Grenoble:

Or the A75 with 7,5%:

7% is just too much in a motorway. 6% is usually the limit.

The A75 is just crazy! I've rode it once....

Sure ... NOT!

Look you punk, this autobahn is light years before your Struma, it' just isn't so black. It is also much smoother to drive than anything you ever experienced, so don't talk bullshit.

where is it lightyears ahread, jsut because it has more signs and maybe a few electronical signs? Does it have bridges, s it build on a higher fundament than the surroundings, does it have trafficlight junctions on the exits, does the motroway overpass the exits with a bridge?

i find it more interesting when the connected road overpasses the highway that you can have a view on it.


But,
is that IMPORTANT?

That is bad design, because when accelerating, people have to go uphill, so you can't reach the proper speed before entering the motorway.
When exiting, you can use the uphill for a better deceleration.

Third of all, bridges over motorways are socially safer as tunnels.

I may hope so, since Berlin is pretty busy, nothing like the rural Struma motorway...

No, it is safer with exits under the motorway because people wont be able to look up the bridge if there´s trafficjam or a great car which they havn´t seen for example and the chance to make a crash is way lower with how it is on the Struma motorway.

ok, so there shouldn't be any signs on the highway because when you look at the sign you don't look at the road and you can cause accidents...or great cars should be banned from the highways because if one overtakes you you pay attention to the car and not to the road. you should not make the mistake to think that everybody does what you seem to do. is there really anybody that looks on a small bridge if there's some supercar on it?

what you are saying is simply ridiculous.

@ chris: ac- and deceleration is a pretty good point. i did not think about that. especially for weak cars or trucks it may be important

I have no idea how do you guys do it,but here,we build the exits as they fit into the geography of the area,but usually along the motorway(lack of hills),although the crossroads usually pass them from above.

It´s different if you see for example a crash or a trafficjam on a bridge or if some Porsche overtakes you, ofcourse it´s not that important aber Kreuzungen über die die Autobahn drübergeht, mit glänzenden Leitplanken und Brückengitter ist einfach cooler!!!

And Chris, you are very ridiculous and amuze me, do you really think they build the bridgeexits because it´s safer for you, if you think that, than I don´t know what to say, you can worsip the German autobahns but this simply goes too far.

Don't make me to do some analysis of Struma motorway and their exits. There are some things you're hiding from us.

Anyway, this new A113 is a splendid example of urban motorway.
However shafts should be removed from pavement. Bad design, I must say. But it happens all the time everywhere.

There should never be shafts on a motorway

On an urban freeway/motorway/autobahn, it's considered a good design principle for the freeway to pass under the city streets, because in times of high traffic, it becomes very disconcerting to people to not be able to see over the bridge. They get distressed because they don't know if traffic is stopped on the other side, or if there is someone going slowly in their lane, etc. In Houston, for example, most of our freeways pass over the crossing streets, and there are huge backups caused by this.

And yes, this is a very good looking stretch of autobahn, though it does need an emergency lane in the center!

Be happy there's even an emergency lane on the right. Lots of countries don't have emergency lanes on the left, only sometimes at very wide stretches (4 lanes or more in each direction).

Why should there be an emergency in the center? Cars should be only in the right lane,and only overtake in the left ones,so there is no need for an emergency lane on the left IMO.

Very true, in a rural setting. However, in the city, traffic is often too heavy for all cars to be queued up in the right, so in case of a breakdown, it makes it much easier for a car in the left lane to pull to the center than disrupt traffic by cutting across the other lane.

Emergency lanes in the center aren't used in europe.
Only in north america, as far as I know.

Not something necessary in my opinion. If you have it, great, but an emergency lane only on the exterior side is enough. At least here in europe where 5 lanes per direction is the maximum you can see (and very rarely).
