Extension of the Network<br />

facilitating relations and reducing<br />

the economic and tourist exchanges.<br />

The opening of the Corrèze<br />

theme space at the rest area of the<br />

same name is scheduled for spring<br />

2003.<br />

■ To overcome the technical difficulties<br />

encountered at Saulières,<br />

the A89 has been linked up to the<br />

A20 to the north of Brive, thanks to<br />

a 5 km stretch between the A20 at<br />

St-Pardoux-l’Ortigier and Saint-<br />

Germain-les-Vergnes.<br />

This stretch, created by the Corrèze<br />

Département with <strong>ASF</strong> financing,<br />

will be opened on February 21,<br />

2003 at the same time as the 21 km<br />

Tulle-Est/Saint-Germain-les-<br />

Vergnes section.<br />

■ Out of the remaining 52 km, to<br />

reach Clermont-Ferrand, between<br />

St-Julien Sancy and Combronde,<br />

<strong>ASF</strong> obtained agreement in <strong>2002</strong> to<br />

take early possession in all the communes<br />

and the necessary administrative<br />

authorisations to start the<br />

work. The preliminary ground clearance<br />

work and the construction of<br />

the Sioule viaduct have started. It<br />

should still be brought into service<br />

at end 2005-beginning 2006.<br />

A89 WEST<br />

■ Work continues on the 35 km<br />

which will link Mussidan to<br />

Périgueux. It should be brought<br />

into service beginning 2005.<br />

All the expertise of the <strong>ASF</strong> teams is<br />

necessary for this section which<br />

crosses a particularly complex zone<br />

geotechnically speaking: crossing<br />

overhanging two chalk cliffs, passage<br />

over underground quarries.<br />

In parallel, the upgrading to motorway<br />

standards of the RN89 continues<br />

perpendicular to the<br />

Périgueux by-pass.<br />

■ The 32 km of the Périgueux-<br />

Est/Thenon section will be completed<br />

beginning 2004.<br />

The ground clearance work and the<br />

laying of the subgrade surface were<br />

completed in June <strong>2002</strong>. The<br />

laying of the road surfaces and the<br />

construction of the full lane barrier<br />

of Thenon started in July <strong>2002</strong>. The<br />

southern apron of the viaduct over<br />

the Douime (290 m long) has been<br />

completed: the delivery of the<br />

structure is scheduled for May 2003.<br />

Environment assessment of the Angers/Cholet - A87<br />

To take into account the diversity of the sites encountered, <strong>ASF</strong> has carried out a<br />

highly refined landscape study. Results: architectural projects with a powerful<br />

identity; two remarkable civil engineering works, with a turquoise framework and<br />

dark green ledges (Layon and Hyrôme viaducts), many specific arrangements to<br />

protect the water, wildlife and plant life, the planting of 245,000 plants. The route<br />

was optimized to limit nuisance to those alongside the motorway: however,<br />

acoustic protections have been erected, including 4,300 m of noise protection<br />

earth barricades and a screen some forty metres in length near Angers.<br />
