They were certainly pumping concrete yesterday afternoon by the looks of it and had what appeared to be some sort of apparatus bridging the deck perpendicularly to work whatever they were doing.

Building new Walterdale Bridge like assembling puzzle made with 125-tonne pieces

Constructing the new Walterdale Bridge is like tuning a harp, or building a bicycle wheel. Sort of.
On this bridge — what the city calls its most complex infrastructure project to date — it’s easier to use analogies. The physics involved might make engineering students shudder.
Think of it: steel cables thicker than your fist stretched by several inches as crews poured the concrete deck. Steel arches bent into a target shape as the cables were tightened one by one, like tightening spokes to shape a bike wheel.
Korean steel fabricators — widely criticized for delivering a year behind schedule — didn’t just deliver 125-tonne puzzle pieces, they delivered 42 pieces deliberately misshapen so the forces within the bridge could form it into the right geometry.

“Every one of those pieces did fit; I was really surprised,” said Jim Montgomery, lead designer and engineer with the local firm Dialog, who gave Postmedia a year-end tour with city project manager Ryan Teplitsky.
The $155-million replacement to Edmonton’s century-old Walterdale Bridge is now on track to open two years late. But the arch is up, the deck is poured and crews will start assembling the graceful swoop of the east-side pedestrian path in February. When the weather warms up, they’ll finish the water-proof coating on top of the concrete and lay the protective asphalt driving layer. It should be completely finished by fall.
Despite the delays, it’s meant to be an iconic structure defining Edmonton’s river valley for the next 100 years.
Millions in late penalties and still no opening date for Walterdale Bridge
The contractor is facing penalties totalling $17,000 per day because of delays
maybe they're just trying to match the condition of the low level bridge spans and other existing bridges so there will be some consistency to our crossings. some cities use colour, some use lighting, we use rust...

Last section of the Pedway is being installed. That would be the last major component installation. So the cranes should be coming down next week. I also see they are starting to paint the lift points and connectors.
