A little primer of the European Interstate System

When the European Union was created, one of the big changes came to the European freeways all across Europe. While people did not notice most changes, one of the biggest changes was the signage and the color of the guide signs. Most changes are to bring European freeways up to the standards set by the United States, Canada, and most countries in the Far East. Here are some changes that came in the past decade:

Signs

This sign you see above is the sign for the Germany Autobahn. It's a hexagon that looks like that and is has white numbers on a blue shield.


This sign looks similar to Germany, but it's the sign for the Switzerland freeway system. The only main difference is that the sign has white numbers on a red shield.


This sign is the EU route sign. This is found on European freeways provided that the freeway meets the standards. This sign, like any route marker, must be posted with the other highway route markers at distance signs and on control cities.


This is the Auto route sign one normally finds in France. This style is also used in several other countries, but usually in a different color. The France Auto route shield is blue.

Other European highway signs can be found on James Lin's page or on Mark Furqueron's Page

Guide signs

Unlike the United States, the guide signs on European freeways are required to be blue under the European Union Highway System. An example of this can be found on Mark Fuerqueron's page. (Note: you will have to do some scrolling.)

I have built a small table of the differences one finds between the German Autobahn and the United States Interstate System. This table is under construction as I speak.

Highway numbers and EU numbers are posted at the bottom of the distance signs you after pass an exit. They are also required to be posted at the bottom of signs with control cities and above arrows in an interchange with yet another European freeway. The only exception of this is France, where they're posted above the control city sign.

Here's two photos of freeway guide signs in Europe with this feature (photos by Mark Fuerqueron).

Not all countries number their exits. In instance, Switzerland does not number their exits on their Autobahn and France does not number exits on all their Auto routes. (Most do -- but a couple that I was on in France near the France/Switzerland border didn't.)

Like the PASHTO rules in the United States, no two highways with the same number are allowed to be multiplexed (note: not all EU routes are multiplexed onto other routes), and most countries don't allow duplication of state and federally maintained routes. (The only countries known to duplicate routes are Spain and France. Germany once did, but decided on a highway numbering pattern.) Most countries have some highway numbering practice implemented.

This page shows a sample distance sign in most countries in Europe on their freeways. Germany, however, uses a slightly different version of distance sign, but the highway number is posted on the sign. For an example of one, go to Hyde Flippo's Autobahn page. Netherlands posts distances to control cities on the overhead guide signs (see left photo above).

Freeway rules

The freeway rules are simple but not enforced by all countries. Before you go to Europe, you should check with that country's freeway rules.

These series of rules are patterns that I observed when I was in Europe in June 1997. Keep in mind that each country has different rules regarding to their freeways.

  1. The minimum speed limit shall be at least 40 mph on freeways. All freeways must be built to at least 60 mph design speed. (This depends on country and/or terrain where the freeway is in.)
  2. The speed limit is determined by the country and shall be enforced by that country.
  3. Toll ways are allowed to be included in the EU Freeway system. (For example, most of the auto routes in France are toll, and the entire Autobahn system of Switzerland is likewise, even though there is a "mandatory" E-Z Pass rule implemented in Switzerland.)
  4. The main highway should avoid the downtown area of a metropolitan area whenever possible. (This should tell why there aren't many expressways in downtown Paris and why most German Autobahns bypass cities.)
  5. Highway markers must be posted with numbers. Countries may use letter suffixes if they prefer to (i.e. M30) to identify freeways from arterial routes. (I. E. France, Netherlands, and Spain do this.)
    This photo I've taken in June 1997 is a guide sign leading to the A-5 in Germany. This photo was taken from a service area about 2 hours south of Heidelberg. This photo relates to Rule 5 in some extent.
  6. Freeways may multiplex with any number of other highways and/or EU routes, as long that all route numbers are different and are posted on the distance signs and/or signs with control cities. (Note: EU routes are not required to be multiplexed for the entire distance.)
  7. If a country chooses to send a route through the heart of the metropolitan area, that route should be marked with a 3 digit number. (Germany does this rule a little differently.)
Most rules are similar to those in the United States and Quebec. However, most countries in Europe don't have an numbering scheme like the Interstate Highway System (except for a few countries and the EU route system), so you will find odd numbers going east/west and north/south in some countries and likewise for even numbers.

Frank from Action maps has just returned from a road trip in Italy and has this to say:


Hi,

The main thing I didn't get to do, regrettably, was photograph signage, etc. because I was the one doing the driving, and I wasn't alone--there were four of us.

Italian roads are essentially excellent like all those in Europe, except for the major differences which are what I would call "cultural," or "traditional." Like, they don't EXPECT to have a shoulder on each side of the road as wide as a car, so here you are on a main highway with just two lanes, exactly, with the tall weeds right up to you wheels. And then there's a bunch
of bicycles in your lane as you round a curve.

Europe has not accepted the yellow line as a traffic direction separator. All road striping is white.

Italians pass anywhere. You're on a two lane road with traffic coming the other way and the guy behind you just gets out there and goes past, usually squeaking in by a foot. And this is common. After awhile you say, hey, I'm gonna be Italian, here goes! And when you decide to go for it, you better finish it--no balking. Of course , your European car will do what you ask of it. We had an Opel Vectra that moved.

There are two kinds of expressways in Italy, really, whereas we only have one (expressway/Interstate). The Autostrada is the full-blown four lane (or wider near cities) expressway, with average speeds in the 80 mph range. Watch your rear-view mirror, however, frequently, and NEVER sit in the passing lane for longer than it takes to pull your maneuver, because some Mercedes with German plates doing about 130 mph will blow you off the road.

Autostradi are numbered with the letter "A", as the A1 the main road from Milano to Roma and Naples. Funny, though, about route signage. Everywhere within a hundred miles at countless junctions you will see signs pointing to "A1 ROMA," for example, but when you're ON the Autostrada, the overhead signs near exits only use the E-route number, as "E45 ROMA" with a down-pointing arrow. E numbers (shown on all maps) are never seen off the Autostrada.

All bridges are numbered in the center median, though, with the sequential number of the overpass and the route number above.

The second category of expressway I think was called "Superstrada" or sometimes the sign at an entrance would just say "To the 4-lane to Florence" in Italian. An example is the road between Florence and Siena. It is completely controlled access, with exits about every five miles, but there may be a lower speed limit (like 90 kph), the lanes aren't as wide, and the whole thing just "feels" like a second class expressway.

These seldom have route numbers since they were built later than the main road system. On the kilometer markers where the route number ordinarily goes, the name will be. For example the above-mentioned road is the "Raccordo Siena-Firenze," the Florence-Siena Connector.

The ring road around Rome is known as the Grand Raccordo Anulare, (big bypass, or ring-road), shown on road maps as the G.R.A.

On the route shields along the road they actually use the GRA letters as the route number, so within the green octagon where it would say "A1" it here says "A G.R.A.", the A on the top line, the G.R.A. below within the octagon.

That's it for now, gotta go.

There are a few highway links regarding to traffic rules and freeways in Europe.

Most info was provided when I went to Europe in June 1997 and some patterns were found on road maps and by personal experience. If anyone has better information, they should email me with it.

Special thanks to James Lin for some of the gifs and to Ty Rodgers for the gifs I used on the distance sign. Most autobahn images came from this download site that is in German, but all you need is a photo editor and something to unzip the files. (Be sure to reduce the photo width by 50%, too.) e-mail
