Let's not be hasty here.
Phase 1: Piles and columns
The station remains open during regular operating hours. Construction occurs only at night after the last train has left and before the first train arrives.
Phase 2: roof beams
The station closes for one week while beams are laid across the columns. The old station canopy is removed as part of this phase.
Phase 3: Concrete floor
The station remains closed for another week while steel flooring sheets are laid out, rebar is fitted, and concrete is poured. The old catenary line is replaced with a new indoor-rated system
Phase 4: Curing
One week passes for testing of the new system before passengers are allowed to use the new station.
Phase 5: Construction continues
The station reopens for business. The rest of the terminal is built up around the TRAX station. Work within a close proximity of the station is required to happen only at night when the station is closed (such as building the walls that will enclose the station) but these items are minor. All construction work above the station no longer affects the station itself since there is a concrete floor between that work and the station.
Total station closure time: 3 weeks.
I think we're both making good arguments for and against the two station alternatives, and it just comes down to a matter of preference. There really is no engineering impossibility in the construction of either a good elevated or enclosed ground-level station; it just comes down to timeline, politics, money, and preference.
I'm just excited that we're getting a better connection at all, considering all the shenanigans involved in this relocation.
