Wow. Page 8 of the paper talks about box-jacking in pre-built (on-site) underpass tunnels in a matter of days. These are 42'x29'x146'/126' and they hydraulically jack them laterally into place in a matter of days with no "dig and cover". The LIRR is doing the same thing and doing it over the weekend with union labor doing it for the first time with instruction from the Italian company that pioneered the technique. The LIRR ones are slightly smaller at 40'x24'x112' but this is impressive!
Innovative box-jacking method from an Italian engineering firm is deployed for the first time in the U.S. for LIRR's grade-crossing elimination project.
Here is a brand new detailed progress report, which includes a map (p. 11) showing WDW access via SR-536. The map also shows proposed SunRail service ... open in 2022.
Also, the Tampa extension is projected for 2029. with no Lakeland stop at this time.
