A-Lanes A15 is a consortium comprising Strukton, Ballast Nedam, John Laing and Strabag. The consortium's sustainable solutions for designing, building, financing and maintaining infrastructures will guarantee maximum traffic flow and safety on the Maasvlakte - Vaanplein section of the A15, both during and after construction works.

The A15 is an important link between the expanding Rotterdam port and industrial region and its European hinterland. The contract has a duration of 25 years and a total nominal project valuation of around € 1.5 billion. The A15 Maasvlakte-Vaanplein project is thus the largest project ever put out for tender by Rijkswaterstaat (Directorate-General for Public Works and Water Management).
