I think this scenario is reasonable, but if there is a need for a downtown tunnel it is on Guadalupe, not 4th Street. Guadalupe already carries a significant amount of automobile and bus traffic. Reserving two lanes (or one on Guadalupe and one on Lavaca) for 100% transit dedication for both LRT and buses could be challenging. That kind of happens now, but the 'reserved' lanes are often impeded by right turn movements and cars ignoring the lane reservations. Proper LRT stations also require more space than the existing bus stops on Guadalupe and Lavaca.
4th Street has very little traffic on it, and most is circling for parking. 4th Street should become a transit mall, with the elimination of street parking and limited auto access to those few buildings that need access to 4th for parking or loading. Those can be handled by a single one-way lane that only allows circling that particular block, and not through movements.
Under this scenario, the likely connection between the downtown stations is made primarily by the Gold Line BRT. I predict that the Trinity Crossing will be eliminated in the definition of Minimum Operable Segment (MOS) that this is leading towards. Both Orange and Blue LRT will cross LBL in a shared crossing near S 1st (either tunnel or new bridge because the existing Drake bridge cannot accommodate LRT without significant rebuilding). The lake crossings are the most expensive part of the proposed system, whether tunnel or bridge, so it makes sense to develop only one initially and reserve the ability to build the second in the future. The Trinity crossing would make the most sense once the Gold Line BRT is replaced by a Blue Line LRT extension, as originally envisioned.
