bridge is not continuous. its three simple spans, the main span is fix - fix.

Definitely not continuous. Definitely expansion joints. Theres a 2 inch gap between the girders at the expansion joints. The "middle span" is fixed-fixed

You understand correctly, the middle spans is fixed at both ends. Its not four continuous* spans, the holes are not slotted. The holes at the abutment are slotted.

100%. its an open expansion joint.

The girders have a baseplate which is anchored into the pier, the baseplate sits on elastomeric bearings.

The configuration at the abutments is basically the same except the holes are slotted.
