Professors from German universities, all experts on underground structures presented the alternatives for a tunnel solution between Dejvice and Veleslavín.

A south route has been decided upon. The exact route of the tunnel will be determined later in October.  In any case the route will go under historical buildings but vibration is expected to be very low because it is soft soil area. The experts have also looked into the alternatives for tunneling. NATM, TBM or Cut & Cover.
