Launching off the ground and over the river

From ODOT-
These photos show where the new northbound Willamette River Bridge will launch off the ground and be suspended over the river. It will be a virtual twin to the new southbound span.

Above, you can see the top couple of feet of the new bridge piles, which were driven deep into the ground to help support the north end of the new bridge. The piling is enclosed in steel caps and a new retaining wall was built behind them.

Above, crews have surrounded the pile caps with reinforcing steel and are building the wooden falsework to create the bridge abutment. Next, they will pour concrete into the forms to create the foundation for the north end of the new bridge. The white material on the left is the form liner, which is used to create the textured finish on the exterior of the new abutment.

Here is a close-up of the textured form liner.
