Project description
In 2003, the commercial area of Alfragide, located on the border between the administrative regions of Lisbon, Amadora and Oeiras, was characterised as a heavily industrialised area that hosted four major commercial surfaces: Aki, Decathlon, Jumbo and Makro. This was the location chosen by the Swedish group IKEA, world leader in the distribution of furniture and home decoration articles, to establish its first store in Portugal.
The expected increase of traffic due to the proximity between these large commercial establishments and consequent traffic jams imposed the reformulation the entire surrounding road network as a necessary condition for IKEA’s settlement in that area.
Being an area subject to strong land use and occupation constraints, of complex territorial management due to the involvement of two municipalities and of the Instituto de Estradas de Portugal, there was a need to intervene in approximately 1.850 m of EN117, altering its cross section from 2 x 2 to 2 x 3 lanes, and in 3.600 m more on the Amadora and Oeiras road network, improving and widening some of the pre-existing streets. The intervention also included the creation of an extra 2.000 m of new accesses, namely the construction of two viaducts, to segregate the local traffic connecting the stores from the EN117 traffic and to establish a fast and smooth connection to CRIL.
A1V2 developed the detailed design in the areas of geometry, earthworks, drainage, signalling and security equipments.
