Roads of the Haute-Garonne

Cartography

The network in 1750 - Charts of Cassini

From 1750 to 1784, the whole of the highway network for the first time is charted with large scales (with the 86.400ème) and in a complete way by Cassini de Thury, at the request of Louis XV. These charts are of a great toponymic richness, but of a great poverty as for the figuration of the relief and altimetry. In the same way the secondary ways are seldom represented, because of a share of their poor state, in addition of their low economic importance.

The network in 1850 - Chart of Levasseur

The illustrated national Atlas carried out by Victor Levasseur is an invaluable testimony of the XIXe century, the charts colored with the hand are surrounded by engravings indicating statistical, historical notes and illustrations characteristic of the departments. On these charts are represented the roads, railways and ways of water. In addition, the departments are divided into districts, cantons and communes.

History

This section has the aim of counting the great stages of the development of the highway network of the department of the Haute-Garonne.

Characteristics

The length of the highway network of the Haute-Garonne is as follows established in 2007 to xxx km being distributed:

Highways

A61 , of the peripheral Is of Toulouse (fine of A62 and exchanger with A68), at the department of the Aude, on 46 km.
A62 , of the peripheral Is of Toulouse (fine of A61 and exchanger with A68), at the department of the Tarn-et-Garonne, on 30 km.
A64 , of the Western peripheral of Toulouse, at the department of the Hautes-Pyrénées, on 99 km.
A66 , of A61 on the level of Montesquieu-Lauragais, the department of the Ariège, on 26 km.
A68 , of the peripheral Is of Toulouse (junction of A61 and A62), at the department of the Tarn, on 46 km.

Other fast tracks

Peripheral of Toulouse :

A620 , the Western peripheral of Toulouse, which is connected to North in A62 and the South in A61, and 19 km is long.
A621 , of the Western peripheral (A620) to the airport of Blagnac, on 3,5 km. Constitute part of the Wire of ARIANE.
A623 , of the Western peripheral (A620) to the ex-RN113 on the level of Ramonville-St-Agne, on 1,5 km.
A624 , of the Western peripheral (A620) with the RN124 on the level of Colomiers, on 6,5 km.
D901 , section of one kilometer and half between A624 and A621, constitutes the other part of the wire of ARIANE in direction of the airport.
D980 , known as by-pass Rainbow, of the name of the logo of the general advice which financed it. This second by-pass in the South-west of Toulouse connects A624 to A64, over a length of 8km, of which only the 5 first for the moment are arranged in fast track.

Others :

A645 , of A64 on the level of Montréjeau, the RN125 with height of Seilhan, on 4,5 km. Constitute the by-pass Montréjeau.
A680 , of A68 to height of Gragnague, in D112 on the level of Verfeil, on 8 km.

Trunk roads

Since the reorganization of the highway network in 2006, the trunk roads are limited today to the adequate portion:

N124 , of Colomiers (fine of A624), at the department of the Gers, on 10 km.
N125 , of Seilhan (fine of A645), in Spain (Bridge of the King), on 31 km.
N224 , of D902 on the level of Beauzelle, the department of the Gers. This section of the Route to Large Gauge, intended for the transport of the parts of the Airbus A380, measurement 21 km.

Secondary roads

Old Main roads

ex- RN20 , newcomer of the Tarn-et-Garonne in North, Toulouse beam, to lead in Ariège to the South after 70 km. Its downgrading is explained by the doubling of its route in the North of Toulouse by A62, and in the South by A61 then A66 in direction of Pamiers.
ex- RN88 , on the basis of Toulouse to lead to the North-East at the department of the Tarn after 27 km. Downgraded because skirting A68.

D633 , old RN633 displaced in 1972, and completely located in Haute-Garonne. Connect the ex-RN117 (Montréjeau) to Boulogne-on-Gesse in 29 km.
D635 , old RN635 displaced in 1972, and completely located in Haute-Garonne. Connect the ex-RN117 (Boussens) to Boulogne-on-Gesse via Aurignac in 32 km.

Recent achievements or events

This section has the aim of counting the big events concerning the field of the Road in the department of the Haute-Garonne since 1990. The declarations of public utility, the beginnings of work and the startups will be thus quoted. Only the most important works either by their cost or by their impact (deviation of boroughs) will be taken into account. In the same way it is desirable not to count the projects which were not the subject yet of a declaration of public utility.
