The last trusses were reconfigured Friday, giving 18 feet of clearance for all traffic lanes.
The Skagit Valley Herald reports there may be some short closures this week to finish maintenance and painting.
A section of the bridge collapsed May 23 when an arching truss was hit by an oversized truck. Workers installed an emergency span and then replaced it with a permanent span.
New squared-off trusses should prevent a similar strike.
