The first of three intersection renewals on the Carlton and Dundas routes began on May 14 at Gerrard and Parliament Streets. Intersections at Broadview/Dundas and Broadview/Gerrard will follow in June and July, as well as track renewal on Broadview between Dundas and Gerrard. Planned renewal of the track from north of Gerrard to Hogarth (the north end of Riverdale Park) has been deferred to a future year, as yet unknown.
Demolition of the intersection began on the morning of Monday, May 14, and by late afternoon Wednesday, May 16, the new foundation was in place and ready to receive track. I happened to drop by just as the first track panel was being unloaded and placed in the street.
Intersections are pre-assembled at Hillcrest before they are delivered to the site so that they can be installed in panels rather than individual parts, a much more labour intensive process once used by the TTC. Preassembly also allows pre-welding of all components in one panel, and the only on-site welding required is to join panels to each other and to odd pieces of track that individually complete the junction and approaches.
Day 4: May 17, 2018
At the time of my visit in the early afternoon, the south quadrant had been installed and assembly of the middle of the intersection was in progress.
Day 5: May 18, 2018
As of mid-day, most of the north-south trackage is in place including the run off tracks that will link to the existing track beyond the work site. Welding was in progress. The eastern quadrant appears ready to receive its track panels.

Day 7: May 20, 2018
The intersection is now almost completely assembled. Concrete work will follow in two separate stages: one to the height of the ties, and another to the railhead. This arrangement makes repairs easier because only the top layer needs to be demolished.
