But each of the options show a difficulty. The first : if the Angers inhabitants use it to cross the city, that bank of the Maine river could be permanently held up and Angers would meet again the situation it faced at the end of the 70's. The second option show also a technical difficulty : the tunnel digged on such a distance could be vulnerable to floods and would have to be flooded too in order to balance the pression the river will have on the tunnel when the water level is high.
