On September 22, 2010 it was decided to build a tunnel version (3,05 billion euro) of the BAM-route. The additional cost (352 million more than the cost of the ‘flyover version’) is to be met by the City of Antwerp and the Port. It was also confirmed that an underground A102 (700 million to 1 billion) is to be constructed, but only after the BAM-route has been completed. In addition, the final negotiations have resulted in a decision to construct a tunnel version of the current R11road (425 to 530 million euro), connecting the E313 and the E19 highway, after 2021. The global cost of Oosterweel connection, A102 and R11 is calculated at 4,2 billion to 4,6 billion euro. Existing plans to enlarge the entire R1, as proposed in the Antwerp Master plan since 2004, would become obsolete after the construction of both tangent roads east of the city, and have been scrapped accordingly.
