Lots of piers still have to be built. Then you still got to cap the ones being built before the beams can be place on them.All of the elevated sections for the 403 overpass look like they are about to be put in place.
The 2 spans over Rathburn could see beams in place next week and well depend on the centre pier and weather. The centre pier has been under heating protection for most of the past week. Once that is done, they can deck those beams as well the ones in place. Back filling than take place to bring the line to grade at Sq One Dr.
If I am reading the site right, the area between the eastbound ramp to Hurontario and the 403 will be at an elevated dirt grade level to allow the line to do a T junction. Only the centre pier for the 403 is pour and cap with no end piers for the bridge.
