Yeah, I was a little dissapointed when I saw the pic. After going though 395 tunnel under the US Capitol, 12th street or the Hampton Rds Bridge/Tunnels that cross the bay, I was expecting a little more digging to happen. Even K St. by GWU is more of a tunnel.
I was expecting a straight shot from I-10 to Floyd Curl.
By the looks of the pic, it doens't make sense to have 8 lanes when it is 3 lanes around the turn before Fred rd. Are they going to widen it all the way to I-10? At least 5 lanes (two lanes each way and a turning center lane) near Horizon Hill? Are these the same guys who planned Wurzbach Parkway? Think of the Midas and Whataburger.
I think a 1 mile diret tunnel from the I-10/410 interchange to Louis Pasteur is better.
