Updated May 8, 2015: The TTC has posted a time-lapse video of the reconstruction for those who want to see the whole thing in two minutes.
On Monday, April 6, 2015, the TTC began reconstruction of the intersection at College & Spadina. The work is planned for a three-week interval, and as of April 10 the project is moving along swiftly. During this work, 510 Spadina buses and 506 Carlton cars are diverting around the site. Resumption of through service is planned for Monday, April 27.
As with all such jobs, the work began with demolition of the existing intersection followed by the pour of a new concrete foundation on which the new track will sit. The track was pre-assembled at Hillcrest Yard and then broken apart into panels which have been delivered to the site on many trailers spotted around the intersection. The TTC’s Brad Ross posted an excellent photo on Twitter of the fully assembled intersection.
Reassembly begins with the diamond in the middle of the structure, and works outward to each arm of the intersection.
My thanks to Harold McMann for the photos of early stages in this work.

Assembly of the intersection began on Friday morning, and two days later, it is nearing completion with only the south quadrant still missing. At the end of the gallery below, the track panel that will be the southbound section of the south quadrant is being reading for its move into position.
