Keele St subway continues with unloading of concrete panels

Structural upgrades generally consisting of the construction of five new piers within the parking lot to provide additional support of the bridge deck. All work is being conducted within the property of the commuter parking lot.

10 large diameter caisson holes were augered into the ground; 5 holes on either side of the bridge. Each pair of caissons were joined with a concrete beam that was formed below grade and poured over the caissons. A steel frame will be placed and permanently rest on each of the concrete beams. The steel frames will be jacked up to the underside of the bridge to provide added support.
