Coen Tunnel schreef:Wat voor bord stond er daarvoor dan? Wel een gewoon bord met het woord 'knooppunt' er op? De A4 bestond ter plekke van dat bord al voor 1998, al vanaf Den Haag-Zuid. Waarom is dan op die plek, waar de doortrekking niet plaatsvond en de situatie al enkele jaren zo was, een bord vervangen? Of stond er eerst geen knooppuntbord? (Dat zou ook bijzonder zijn). Ik zie de link met de doortrekking namelijk niet. :dontknow:
Daarvoor stond of een ander bord, of niets, maar de A 4 kreeg toen pas een parallelbaan. Voor dat voegde je vanaf de A 13 gewoon in op de toenmalige A 4. Heb knooppunt Ypenburg nog zien groeien, destijds was die buurt consequent in verbouwing :D
Let op: Sarcasmemodus over een lengte van 10 kilometer.

In die tijd werd ook kp Ypenburg verbouwd en het vlechtwerk tussen Prins Clausplein aangelegd. Dat was volgens mij in 1998 gereed.

Het is wel offtopic nog, maar ik vraag me opeens af: is er überhaupt wel een knooppuntbord voor Ypenburg vanaf het zuiden (A4)? Daar heb ik in al die jaren en jaren niet op gelet. :|

Ik kan het me nog herinneren dat de A4 verder dan Rijswijk er nog niet was. Destijds ging je om vanaf de Prinses Beatrixlaan richting Prins Clausplein rechtsaf, en maakte je een boog linksaf, om zo de A4 op te draaien. Er ligt hier ergens ook nog wel een stadskaart waar de A4 niet verder loopt (of in ieder geval de snelwegstatus bij afrit Rijswijk ophoudt).
Sinds maart 2015 tevens achter het stuur gezien.

Nee, want formeel is het vanaf de A4 vanuit het zuiden geen knooppunt, maar afrit 9. Alleen de relatie A4N<->A13Z is een knooppunt. De andere relaties verlopen via afrit 9 van de A4 of afrit 7 van de A13. Die afritten maken strikt genomen geen onderdeel uit van KP Ypenburg.

Vergelijk het met KP Vught, waar de A65 ook slechts een afsplitsing is van de A2 van/naar het noorden en de andere relaties via de afrit verlopen.

The history of the Cloverleaf Interchange
How to cross motorways split-level
By Walter Brummer
Originally translated from German by René Walhout
The origin of junctions
Shortly after the idea was born to construct specially designed motorways, the question raised how these roads should cross and connect each other. Considering the limited amount of traffic in the early days of motorised traffic, conventional level-crossings were an option. The enclosed drawing originates from the 1929 magazine "Der Straßenbau" (The construction of roads).
An intensity of 1800 motorvehicles per day was rated as “heavily congested” back in 1929, a number now to be found on every town road.
Affected by development in the United States, planners foresaw heavier traffic flows might have to be managed in the future.
To achieve the biggest possible capacity, strong slow down or even full jams had to be avoided. This principle excluded level crossings. How to change from one level to another led to much debate.
On November 6, 1926 the “HAFRABA” was founded in Germany, an association which aspired to construct a motorway connecting HAmburg, FRAnkfurt and BAsel. A member of the HAFRABA board, Herman Uhlfelder from Frankfurt, designed several sketches for interchanges in 1930:
“The full crossing is the primary and most complicated issue. It will be the most frequent one, because in a motorway network crossing usually four stretches will meet. A full crossing has to deal with 12 traffic directions. This results in a crossing with 8 points of convergence, 4 rectangular crosses and 12 crosses under a blunt angle. A total of 8 points of concern and 12 danger points. Structures will only dissolve it partially. Effort should be given to remediate these issues.”
Picture: The “Gothic Interchange” with building costs estimated at 1.4 million Mark (1931) the most expensive of all. The interchange is completely free of conflicts and has only large radii. The disadvantage of the design is within the bends that disrupt the continueing directions. Ground surface: 17 hectare. Number of structures: 8.
Picture: The “Circle Interchange” (roundabout). The simplest as well as the cheapest solution. Estimated at 0.29 milllion Marks in 1931. A limited amount of ground surface and no structures. Unsuitable for modern traffic and now merely in use for the interchange of traffic on slipways.

The “Baroque Interchange” occupies 13.1 hectares and lacks sharp bends. All four left turning curves are on ground level. Number of structures: 4. Estimated building costs in 1931: 0.69 Marks.
The triple invention of the cloverleaf
The most conventional manner for motorways to cross is the so-called “cloverleaf”. Until present day all European publications refer to the Swiss Willy Sarbach as the inventor. However, the world’s first cloverleaf was constructed in 1928 nearby New York City, whose planning had taken place well ahead of Sarbach’s “invention”. This curiosity bothered Alexander Thewalt form Leipzig, Germany. After laborious examinations around the world he concluded the cloverleaf was invented simultaneously by different people on different locations. Key factor was the “rediscovery” of the 1916 patent by Arthur Hale, 11 years before Sarbach’s “invention”.
1) Arthur Hale, Maryland, USA 1916
The oldest patent for a cloverleaf was applied by engineer Arthur Hale on February 29, 1916 with number 1.173.505 at the patent office of the United States. In his application of 9 pages, Hale described 3 designs for a cloverleaf. His base design is shown on the left. The other sketches show more compact cloverleafs, which Hale had planned for urban road networks.
(Source: http://www.uspto.gov )
In 1927, on the banks of Lake Michigan, where two main roads crossed, this grade separated junction was constructed. It shows several similarities with the third sketch from Hale’s patent.
[Source: "Highway Grade Separation in Chicago Park" article in the Engineering News Record, McGraw Hill, New York, volume 1928 (=volume 100), number 18]
2) Buenos Aires and New Jersey, first half of the 1920’s
However, the history of the cloverleaf near Woodbridge, New York leads into another direction. US-highway 1 from New York City to Philadelphia already had an intensity of 26 000 motor vehicles per day in the 1920’s.
Although the US-1 had no intersections, the busiest junctions were frequently troubled by delays and accidents. A creative solution was required.
Edward Delano from the Rudolph & Delano construction company noticed an image of an Argentinian cloverleaf in a magazine. The idea was obtained by the New Jersey road authority resulting in the construction of the well-known Woodbridge Cloverleaf as first of many.
[Source: "Clover Leaf Too Often a Bottleneck" article in the Los Angeles Times, April 7, 2004, page 12]
<< The (official) world’s first cloverleaf was built near Woodbridge in New Jersey (USA) were State Roads 4 and 25 crossed (now US1/9 and NJ35). The cloverleaf was about to be listed as monument, but the decision was made for "widening and curb replacements for both roadways, revised geometry for one ramp, placement of a center barrier on Rt. US 1&9, removal of bridge pilasters, and the addition of modern lights and guide rails." In 2004 the cloverleaf was altered significantly to improve road safety and traffic flow.
This Google Earth image shows the current presentation of the Woodbridge Cloverleaf. In seventy years only the surroundings seems to have changed.
Note from René Walhout:
<< A 1934 design for the Dutch Oudenrijn Interchange shows a remarkable resemblance with the Woodbridge Cloverleaf. Eventually, the Oudenrijn Interchange was built as a much cheaper roundabout (1939-1968).
3) Willy Sarbach, Basel, 1927
Apparently, the American invention was not noticed in Europe, so Willy Sarbach could be considered as the European inventor of the cloverleaf. He visited the 1927 HAFRABA exhibition in Basel were he observed the maps, plans, design and drawings. At home, Sarbach studied for a way to cross two motorways in a straight or aslant angle without any conflicts and with routes in all directions. It resulted in a drawing from which a 3D model was made. On December 23, 1927 Sarbach applied for a patent for his “Anlage einer Kreuzung oder Abzweigung von Autostrassen unter sich oder mit Landstrassen”. The patent was granted on October 15, 1928 under number 129222. His work was rewarded not only by HAFRABA but by the Swiss government as well. However, Sarbach didn’t do anything with his patent.
<< A model of a primal motorway cloverleaf design commissioned by HAFRABA e.V., an 1927 idea of Sarbach.
A cloverleaf owns two advantages compared to other designs: both continuing directions can cross the interchange without bending and only one central viaduct is needed.
Europe’s first cloverleaf is the Schkeuditzer Kreuz near Leipzig, Germany which opened on November 21, 1936. It took another two years before it was complete, it became fully operational on November 8, 1938.
Considering large amounts of traffic, the cloverleaf appeared not to be perfect. Left-turning vehicles must make a 270°-bend followed by merging to the left with low speed, on the same location were other traffic merges to the right to make their 270°-bend. In busy traffic this causes unsafe situations as well as traffic piling up. Another drawback is the difficulty to create multi-lane connections in the interchange. This has lead to new alternatives.
The following design is from engineer Bieligk who wrote the article “Kreuzungen von Autobahnen" which was published in the February 15, 1937 edition of "Der Straßenbau", number 4/1937.


The crossing of two motorways required a solution which excels in clarity on directions at the divergence point and in a good ratio between larger radii and ground surface.
The most essential of this solution lies within the fact that both carriageways are on different levels where they cross. This makes it possible to merge to and from any direction without detours and to continue straight on without bends. Motorists heading left use the left exit, motorists heading straight on use the centre lane and motorists heading right use the right exit.
The crossings of merging and passing lanes have been avoided by locating the left and right exits after one another, instead of on the same location. This allows merging only to the right, in accordance with the applied traffic regulations. An additional precaution for traffic using the exit coming from the passing lane can be effected by applying a diversion strip. This concerns the convergence of traffic flows on crossings as well.
When the lowest carriageway is situated on ground level, a height of 6 metres with the upper carriageway is obtained. The smallest radius at the crossing is 400 metres.
Epilogue by the author: as far as I know this type of interchange was never built.
The major challenge in designing interchanges capable of dealing with large amounts of traffic came with the mass motorisation. In the USA this started in the forties, in Europe about twenty years later. In urban areas existing structures proofed insufficient, so more creative solutions were built, particularly in the USA, where a huge amount of available ground surface was not uncommon.
The interchange between the Great Central Parkway and the Northern Boulevard near the New York World Expo was completed in 1939 and was unique in its size. [Photos from Die Betonstraße Jg.15/Nov.1940]
<< The world’s first four-level interchange was built between 1949 and 1952 in northwestern downtown Los Angeles. Here the Hollywood Freeway US-101 crosses the Harbor/Pasadena Freeway CA-110. Nowadays, with over 500.000 passing vehicles per day it is one of busiest interchanges in the world. The other two are also located in the Los Angeles area.

The first cloverleaf in The Netherlands

<< The “Badhoevedorp Interchange” was the first cloverleaf in The Netherlands and opened on August 8, 1967.
As early The Netherlands were with constructing motorways, so late they were with conflict free intersections. The arrears were swiftly recovered with the conversions of the Oudenrijn Interchange (13-11-1968) and the Hoevelaken Interchange (21-12-1971) into cloverleafs. Bigger and more complicated ones would soon follow.

The history of the Cloverleaf Interchange
How to cross motorways with grade separation
By Walter Brummer
Originally translated from German by René Walhout
The origin of junctions
Shortly after the idea to construct specially designed motorways was born, questions were raised around crossing and intersecting these roads. Given the limited traffic levels during those early days of motorised traffic, conventional level-crossings were an option. The enclosed drawing originates from the 1929 magazine "Der Straßenbau" (The construction of roads).

It appears that the American invention remained unnoticed in Europe. Willy Sarbach could therefore be considered as the European inventor of the cloverleaf. Visiting the 1927 HAFRABA exhibition in Basel, Mr. Sarbach observed the maps, plans, design and drawings. At home, Sarbach sought a way to connect two motorways under a straight or aslant angle without any conflicts, offering connections in all directions. This resulted in a drawing and a subsequent 3D-model.

The patent was granted on 15 October 1928 under number 129222. Not only HAFRABA rewarded Mr. Sarbach for his model, the Swiss government did so too. Mr. Sarbach did not further exploit his patent.
<< A model of a primal motorway cloverleaf design commissioned by HAFRABA e.V., a 1927 idea of Mr. Sarbach.

In comparison with other designs, the cloverleaf has two major advantages. First, drivers in the ongoing direction are not required to exit and second, the structure requires only one central viaduct.
The Schleuditzer Kreuz near Leipzig, Germany, is Europe’s first cloverleaf interchange. It opened on 21 November 1936, but was truly complete and operational two years later, on 8 November 1938.
It subsequently appeared that, where traffic volumes are high, the cloverleaf is not perfect. Left-turning vehicles must make a 270°-bend. Leaving that bend, it has to merge left at a low speed. This merge takes place on the same location where traffic turning left from the intersecting road merges right before its 270°-bend. This causes unsafe situations and congestion in busy traffic. A further downside is formed by the difficulty to create multi-lane connections within the interchange. These difficulties have led to the invention of alternatives.

The following design is from Mr. Bieligk, an engineering who wrote the article “Kreuzungen von Autobahnen", published in the 15 February 1937 edition of "Der Straßenbau", number 4/1937.

The intersection of two motorways requires a solution that stands out with clear directions at the divergence point and with a good ratio between not too sharp turns yet limited surface being required for the intersection.
The essence of the solution is that both carriageways of one road are on different levels where they cross. This permits motorists to turn left, turn right and drive straight on without detours (i.e. being required to make turns of more than 90 degrees). Motorists use the left-hand exit to turn left, they use the centre lane to head straight on and use the right-hand exit to turn right.
Merging traffic will not need to cross the overtaking lane or other merging traffic, since the left and right merging lanes follow another. The basic requirement for motorists is that for any turn-off, the left lane is the primary direction and the merging into that lane only takes place from the right, never from the overtaking lane. This is a rule that follows the general driving rules. An additional precaution against turn-offs from the overtaking lane would be the construction of a diversion strip. This also concerns the convergence of traffic flows following the crossing.
When the lowest carriageway is situated on ground level, a height of 6 metres with the upper carriageway should be obtained. The minimum radius at the crossing would be 400 or 500 metres.
The author added: as far as I know, this type of interchange was never constructed.

Mass motorisation provoked the major challenge in the design of interchanges fit for large traffic volumes. This trend started in the 1940s in the USA, Europe followed about twenty years later. Urban areas were the first areas where existing structures turned out to be insufficient, so more creative solutions were implemented. This was particularly the case in the USA, where there was generally enough land available to implement large solutions. The interchange between the Great Central Parkway and the Northern Boulevard, near the New York World Expo, was completed in 1939. It was unique in its size.

The Netherlands may have been one of the first to construct motorways, but they were very late in the construction of fully grade-separated and conflict-free interchanges. The Oudenrijn Interchange (opened on 13 November 1968) and the Hoevelaken Interchange (opened on 21 December 1971) followed suit. The original at-grade intersections were converted into cloverleafs. Bigger and more complicated motorway intersections would follow.

Helaas is die al een tijdje uit de lucht :(

@palance
zie mijn antwoord van vanmiddag...
op de zelfde manier heb ik ook de uitspraaklijst van het WDR teruggevonden.

Probeer dit: http://web.archive.org/web/*/http://www ... ussprache/
Voor andere webpagina's... gewoon op archive.org gaan, en naast het woord "Waybackmachine" de website invoeren...

Even ontopic: Misschien heeft archive.org ja ook een oude versie van autosnelwegen.nl...
Volgens http://www.wegenforum.nl/viewtopic.php? ... z+#p283911 bestaat zelfs nog een archief van het Board-Z-Forum...

Dit is de eerste wegensite, die ik kende en nu ik het topic eindelijk een beetje heb doorgebladerd, wou ik graag een reactie achterlaten en een paar opmerkingen plaatsen.

Bij het kopje tijdsbeelden staat het stukje A35 dat geopend is in 2000, dat het gedeelte loopt van Enschede-west tot aan Enschede-oost. Dat laatste klopt niet helemaal. Van Enschede-west tot aan Enschede-zuid is het de A35, maar vanaf Enschede-zuid naar Enschede-oost is het gewoon een autoweg met het nummer N35.
Ook heb je in sommige jaren wel het aantal kilometers erbij gezet, hoeveel kilometer het nieuwe trace was, maar voor de andere jaren dan weer niet. Waarom is dat?

Voor de rest een zeer informatieve site, die heel proffessioneel is opgezet en erg interessant is voor mensen die meer willen weten over de geschiedenis van rijkswegennet. :blauweduim:

Tja, de openstellingsinfo bij de tijdsbeelden moet ik echt hoognodig eens verwijderen.
Alleen de info in de dossiers is feitelijk correct.

Het Rijkswegenplan 1927 in juni van dat jaar, is op 4 juni vastgesteld. Die datum heb ik nog niet op je website terug kunnen vinden, dus ik neem aan dat je de exacte datum nog niet wist. Zie http://kranten.kb.nl/view/article/id/dd ... 01%3Aa0006

De kaartjes zijn bij mij nogal korrelig. Het is alsof het plaatje groter gemaakt wordt dan de eigen resolutie. (bv. nergezet met een factor 120%).

Vreemd dat resizen. Ik heb er zelf nooit actief op gewijzigd. De plaatjes horen simpelweg 2x zo breed en 2x zo hoog te worden weergegeven als de originele afbeelding, maar dat gaf in het verleden nooit zo'n wazig beeld. Ik zal er binnenkort eens naar kijken.
