I'm glad you like the idea! My intention was to stay in the I-64 median to Wards Corner, yes - hopping over to NS around the salt shed either just west of the Tidewater Drive interchange, or at Wards Corner, depending on which is less destructive (one has to deal with the HOV lanes in the median, the other has to deal with Wards Corner businesses). With judicious use of retaining walls and a discrete bridge structure, there is plenty of room to bring a railroad up high enough to clear both 13th View and the Willoughby Bay channel. VDOT might have to figure something else out for the contraflow crossover between the bridge and 4th View though.
Since you mention it, I am a bit drawn to the idea if tunneling straight to the Naval Base now... provided that it doesn't interfere with the eastbound road tunnel. A station right on the base would be a much bigger draw for any local service than a station at Ocean View, and then you could tie straight into the NIT line along 564. I had been trying to limit myself to existing public ROWs but I think this might be a better idea, depending on feasibility.

I do mean replacement, if possible. VDOT's concepts were a mixture of replacement and supplementation, and I think replacement would be very beneficial. Part of why we haven't replaced tunnels like the Holland and Lincoln are the historic nature of them. There's nothing historic about these tunnels. These tunnels also carry a major interstate highway with heavy truck traffic, and have fewer alternatives (e.g. the HRBT is frequently closed due to accidents. Depending on your origin/destination pairs the Monitor-Merrimac might be too far out of the way, and the decision point is much farther back, at least on the south side - if the tunnel were wider and included shoulders, a full closure might not be necessary every time. The HRBT and MMMBT are 6 miles apart, the Holland and Lincoln Tunnels are 2 miles apart. Both are also connected do each other fairly easily on each shore - the Hampton Roads tunnels are not). In the interest of both cleanrooming the site to more easily include rail, and bringing the crossing up to modern needs, I feel it would be better to replace them.
Of course all of this is contingent on a cost-benefit analysis of doing so, which will probably favor building new, parallel facilities and then refurbishing the existing.
