'''The Basketweave''' is the name of a stretch of [[Ontario Highway 401|Highway 401]] in [[Ontario]], [[Canada]], immediately east of the [[Jane Street]] [[Overpass|underpass]] in [[Toronto]]; the name derives from the interesting criss-crossing design of the roads, which evokes imagery of a straw basketweave. |
|||
For the westbound Highway 401 driver, the functional aspect of the Basketweave is to allow drivers in the [[express lane]]s to change into the collector lanes, from which they can subsequently enter [[Ontario Highway 400|Highway 400]]. The Basketweave also enables the reverse lane change (from collector to express), acting similar to an express-collector exchange site. Users of eastbound [[Ontario Highway 401|Highway 401]] also enjoy the facility of changing from express to collector, and vice versa, because of the symmetric design of the Basketweave. |
|||
The Basketweave was completed in 1967 as part of a major project to widen Highway 401 to a collector-express system. The flyover ramps were rehabilitated in 2001.{{citation needed|date=January 2012}} |
|||
Toronto-area radio broadcasts often refer to The Basketweave to describe traffic flow along Highway 401, for example: "Eastbound traffic is moving slowly east of the Basketweave."<ref>{{cite web|title= Camera 21 - Highway 401 at basket weave near Jane Street|url= http://www.mto.gov.on.ca/english/traveller/compass/camera/camhome1.shtml |work= COMPASS Traffic Cameras - GTA (401/400/403/410/427)|publisher= Ontario Ministry of Transportation|accessdate= 2010-01-08}}</ref> |

[[File:The Basketweave Toronto.jpg|right|thumb|Looking west toward the Basketweave]] |
|||
===Highway 401 near Highway 409=== |
|||
The main collector-express setup of Highway 401 westbound has a basketweave between [[Islington Avenue]] and [[Weston Road]] at {{Coord|43|42|41|N|79|32|50|W|region:CA-ON_type:landmark|title= Highway 401 westbound near Highway 409 basketweave|display=inline}}. Here, the collectors eventually split off and default on [[Ontario Highway 409|Highway 409]], but the basketweave transfer allows collector traffic to move back onto Highway 401, whose collector-express setup ends at this point (briefly, before reappearing at [[Ontario Highway 427|the 427]] and continuing to the [[Ontario Highway 403|403 interchange]]). Express traffic also has the option of using the overlaid flyover transfer to reach Highway 409. |
|||
===Highway 401 near Hurontario Street (2013)=== |
|||

|||
Another collector-express setup of Highway 401 in Mississauga will have a basketweave between Highway 410 and Mavis Road according to the Ministry of Transportation. <ref>Cited by Ontario's Ministry of Transportation (MTO) as "Golden Horseshoe Project 14"; [http://www.mto.gov.on.ca/english/pubs/highway-construction/southern-highway-2007/expansion.shtml#G14].

===The Transfer=== |
|||
[[File:Highway 401.png|thumb|left|'The Transfer' on Highway 401 near [[Toronto Pearson Airport]] (top of image)]] |
|||
Highway 401 eastbound has another collector-express exchange near [[Toronto Pearson Airport]] at {{Coord|43|39|30|N|79|36|56|W|region:CA-ON_type:landmark|title= Highway 401 eastbound near Pearson airport basketweave|display=inline}}, known as 'The Transfer' on the MTO Compass traffic cameras.<ref>{{cite web|title= Camera 36 - Highway 401 near Transfer (east of Dixie)|url= http://www.mto.gov.on.ca/english/traveller/compass/camera/camhome1.shtml |work= COMPASS Traffic Cameras - GTA (401/400/403/410/427)|publisher= Ontario Ministry of Transportation|accessdate= 2010-01-08}}</ref> Unlike the other examples, the Transfer does not use a flyover structure to separate the criss-crossing transfer lanes; rather, the express to collector ramp passes under a rigid concrete frame structure cut into an embankment. |
|||
This was completed in 1986 when collector lanes were added to Highway 401 between Highway 403/410 and Highway 427, providing a direct link between these freeways. Since the collector lanes beyond the transfer merely serve as ramp extensions to Renforth Drive and Highway 427, motorists wishing to continue eastbound on Highway 401 must leave the collectors at this transfer. Highway 401 express east of this transfer is congested due to only four lanes (widened from three) passing through the 427 interchange; the collector-to-express transfer often serves to make this worse. |
|||
===Highway 427=== |
|||
[[Ontario Highway 427|Highway 427]] also has basketweave transfers in both directions between the [[Bloor Street]] overpass and [[Dundas Street, Toronto|Dundas Street]] interchange at {{Coord|43|38|00|N|79|33|31|W|region:CA-ON_type:landmark|title= Highway 427 Bloor - Dundas basketweave|display=inline}}. This was completed in 1972 when then-[[Highway 27 (Ontario)|Highway 27]] was expanded to its current configuration and renamed 427. |
|||
A major complaint of this exchange is that the collectors south of Dundas are underused due to their complete lack of direct access to the [[Queen Elizabeth Way|QEW]]/[[Gardiner Expressway|Gardiner]]. It is for this reason that the southbound collector to express transfer is busy during rush hour, causing a major bottleneck as it merges with the express lanes, while the overlaid express to collector ramp does not divert enough traffic to compensate. In 2001-2002, improvements were made to the QEW-427 interchange to allow the southbound collectors to access QEW eastbound (Gardiner Expressway) via a new loop ramp, which was supposed to take some pressure off the collector-to-express transfer. However, there is still no southbound collectors to QEW westbound access. |
|||
The flyover ramps were rehabilitated in 2002. |
|||
==Outside of Canada== |
|||
===The Hague, Netherlands=== |
|||
Just south of the [[Prins Clausplein]] (Prince Claus exchange) in the [[A4 motorway (Netherlands)|A4 motorway]] in [[The Hague]] {{Coord|52|3|20|N|4|22|6|E|region:NL_type:landmark|title=Rijksweg 4 The Hague basketweave|display=inline}}, there is a basketweave exchange. To the north of this basketweave, the [[A12 motorway (Netherlands)|A12 motorway]] crosses the A4 in a [[butterfly junction]], to the south the [[A13 motorway (Netherlands)|A13 motorway]] branches off. The A13 and the stack exchange ramps from and to the A12 connect to the outer lanes of the basketweave, the inner lanes are the continuing A4. |
|||
===Eindhoven, Netherlands=== |
|||
Near interchange Batadorp, north of [[Eindhoven]] {{Coord|51|28|30|N|5|24|14|E|region:NL_type:landmark|title=Rijksweg 2 Eindhoven basketweave|display=inline}}, there's a construction like a basketweave. However, northbound it is a choice between two different motorways, and only southbound it is a choice between collector/express motorways. It was built as part of the reconstruction of Randweg Eindhoven. This construction was completed in winter 2009/2010. |
