Today:

Bridge setup complete; Noticed 12 x 3 x 3 block when placed on top of several other blocks rocked when placed down.

Took initial photos of joint: west side approximately 0.05" to 0.06" gap, east side 0.20" to 0.220" gap. Joint appears to be the same as before. See photos.

Will do visual/video inspection and leak check tomorrow morning.
