Dordogne Viaduct, bridge in France

The Dordogne Viaduct is a motorway bridge carrying the A20 over the Dordogne valley on the territory of Pinsac, near Souillac in the Lot department. Its flat grey deck runs in a single straight line, resting on slender vertical piers that stand high above the valley floor.

The Dordogne Viaduct carries the A20 motorway over the Dordogne valley on the territory of Pinsac, near Souillac in the Lot department. The sources consulted document the structure and its location but give no construction dates, so the 1999–2000 dates previously stated are not supported.

The name comes from the Dordogne, the river the A20 crosses here on the edge of Pinsac commune, near Souillac in the Lot. Drivers on the A20 between Brive and Toulouse pass over it without stopping; there is no pedestrian path or viewing point on the deck.

The viaduct is easily accessible from the A20 highway and is used daily by many vehicles. The best way to experience it is while driving or from a nearby vantage point to observe the structure and the landscape below.

The viaduct was built using special construction techniques with prefabricated concrete pieces called voussoirs that were fitted together like building blocks. This method allowed workers to assemble the bridge quickly and precisely while temporary metal frameworks held the pieces in place during construction.
