I have completed an update to the 407 East Extension Construction Page. These photos were taken earlier in November. Construction i still ongoing, so things may have changed somewhat since these photos were taken:

Easterly view from Brock Road

The Sideline 14 overpass

Westerly view from Salem Road

Three level Highway 407/412 interchange

The Anderson Road overpass situated behind a big brother gantry

Crossing of the east branch of Oshawa Creek near the eastern terminus of the Phase 1 extension.
All of the photos are available here:
