Widening of the A-3 motorway to a third lane along the Chiva–Valencia section, between kilometer points 328+000 and 352+000. The project includes, in addition to the construction of the third lane, the reconfiguration of interchanges and access points with the A-7 motorway, Manises Airport and other collector roads, as well as improvements to the horizontal and vertical alignment of the roadway between km 331+500 and 333+000.

The project comprises the construction of four retaining walls and nine structures for vehicle crossings, including two post-tensioned structures, one composite structure, three girder bridge decks, an underpass beneath the A-7 ramp supported by diaphragm walls, and a frame-type structure, as well as the construction of eight pedestrian footbridges. It also includes the upgrading of the existing drainage system, the installation of road signage, safety barriers, and the relocation of affected utilities, in line with the semi-urban nature of the project.

During the execution of the works, traffic diversions and management measures were implemented, maintaining the highest level of safety for users at all times and ensuring uninterrupted service on the motorway.
