This summer, the TTC will rebuild the special work at the intersections of Broadview with Dundas and with Gerrard, as well as replacing the tangent track between these two locations. Minor repairs are also planned between Gerrard and Danforth.
This post will track the progress of the work.
As of August 9, the TTC has announced that the intersection will reopen to traffic and normal routes for 504 King, 505 Dundas and 506 Carlton will resume on Sunday, August 12 at 7:00 am.

By the fourth day of the project, the old intersection had been demolished and the new concrete foundation was nearly ready for the new track.

On day seven, the intersection is fully in place, and work is in progress on various connecting tracks.

These photos illustrate the first stage in replacing track that was built with the now-standard three-layer technique. At the bottom is a concrete slab, and in the middle layer are steel ties with mount points for Pandrol clips that hold the rail in place. The top layer of concrete goes from the top of the ties to the rail head.
In the first photo below, the machine is cutting away the concrete between a pair of rails to the depth of the first layer and throwing the spoil into a dump truck. The second photo shows the resulting structure with the rails still in place, but only a narrow band of concrete on either side. In the third photo, the remaining concrete is broken away from the track.

The photos below work north from Dundas Street. In some of them, the old track has been removed while it others it remains in place. The last photo shows the result after the track is removed with the connection points for the Pandrol clips exposed but not yet cleaned up for new track installation.

The photos below show the progress of attaching new rail strings to the pre-existing structure.
In the first and second photos, the attachment points for the Pandrol clips are exposed, but the rail strings have not yet been placed.
In the third photo, the rail is positioned on the ties, and the rubber vibration insulation has been placed around the rail.
In the fourth photo, the clips have been installed locking down the rails.
In the fifth photo, covers have been added over the clips, and concrete work (in the foreground) has already begun. A gauge bar is used to verify the rail spacing. Although the attachment points for the clips effectively dictate the gauge, there is a bit of play, and the rail is checked and adjusted if necessary before the concrete pour.
In the sixth photo, the concrete pour is underway north from Dundas.

Demolition of the old intersection at Broadview & Gerrard is well underway. Work began on July 24.

Most of the concrete foundation is in place ready for track to arrive.

The central diamond had been placed and part of the southern quadrant was roughly in position when I visited about noon. The diamond is unusual in that it is not a 90 degree crossing, and there the curve coming out of the east side begins within the diamond itself. Also, the intersection slopes from south to north.
The only other intersections with a non ninety degree diamond are at Bathurst & Queen, Dundas & McCaul and College & Spadina. [Thanks to reader “Max” who pointed out the Dundas/McCaul location, and L. Wall who pointed out Spadina & College both of which I missed in the original article.]

At midday, the intersection was almost completely assembled with only the approaches still in progress. The City of Toronto tweeted yesterday that the intersection work is ahead of schedule and should open on August 20.
Great news! Broadview & Gerrard St E expected to fully reopen by Aug 20, ahead of schedule as crews make excellent progress on TTC track replacement. Thank you for your patience during this work. [Tweet from @TorontoComms August 1, 2018]
Diversions in Progress
The assembly of the intersection will likely take the balance of the week through to August 4, and then there are the connection tracks to the adjacent structures. Once concrete is placed, it would be about a week before before traffic could return. This has now been announced for August 12.
504 King and 505 Dundas buses have shifted to use the roads connecting to Gerrard at St. Matthews. 506 Carlton buses divert via River, Dundas and Logan both ways. When the intersection reopens to traffic, the replacement bus service will operate on the normal route. Streetcars return to 504 and 506 on Sunday, September 2.
The TTC has confirmed that although the Board approved addition of a north-to-west curve at this location back in 2010 (along with other changes), corporate amnesia caused this to be omitted from the current work.
