On March 4, 2009 the results of this independent survey were announced. Its conclusion was not very encouraging for the BAM-route. The report concluded that all routes were technically feasible, but none of them were profitable in compliance with the Flemish Government's prelimiting conditions, the BAM-route would be 400 M euro cheaper than the stRaten-generaal layout, and, since the former project was in a more advanced stage of development, it would also be finished sooner. The stRaten-generaal project came out on top regarding all the indicators of sustainability (mobility, the environment and quality of life). The Horvath-route, with a tunnel exactly on the same route where BAM wanted to build the Lange Wapper flyover, turned out to be the most expensive of the three, as well as the lowest scoring on indicators of sustainability. In its conclusions, the consulting agency suggested better management of vehicle usage of road infrastructure, implementation of electronic toll systems and optimisation of stRaten-generaals proposal of a boring tunnel further north.
