Actually, you need 2 short tunnels, there need not be a tunnel in the middle, which can help the tunnel be more pleasant.
The proposed causeway is enormous, almost 1/4 of a km long. Leaving aside the expense, such a long distance takes away the opportunity to make recreation space in the green area, as well as a direct connection to Dutton Dr.
A bridge must be significantly higher because double large trucks use the highway, where as even a high airy human sized tunnel would be significantly smaller.
