Geovia supporting the restoration of the A1 motorway after the collapse of a dike on the Mondego River.

11 March 2026

It was after this incident that BRISA requested support from Geovia to find a solution to repair the A1 embankment to restore circulation on the country´s main road artery. Geovia defined, together with BRISA and LNEC, the solution to restore circulation in the various phases of opening to road traffic (the 1st phase in the south/north direction on February 23rd and the 2nd phase in the north/south direction on February 27th).

Throughout the study of this solution, Geovia leveraged the multidisciplinary expertise of Norvia Group: LCW provided suport for the structural components, while MSW focused on the river hydraulic component. A joint, dynamic and focused effort that allowed the A1 to open to traffic after just 17 days of repair works.
