expansion loops to accommodate steel pipe on suspention bridge at river crossing
(OP)
I’m looking for recommendations/types for ground expansion loops to accommodate pipe expansion concerning (4) steel pipelines supported on a suspension bridge at 300 ft wide river crossing.

Depending on the size of your pipes to make them piggable you could need some fairly big loops. Either that or arrange for 90 degree bends then a set length of flat pipe before another 90 bend then go underground to accomadate the expansion if you want flat pipe.
The issue with flat pipe on a suspension bridge is how to control lateral movement / spring as the bridge won't give you much if any support.
A plan, sketch or picture would be good to see what you're talking about.

Here's an arch bridge for pipelines. Expansion doglegs. Notice the other bridges in the area as well and how they handle the expansion there too. You can also see these in StreetView from Interstate Hwy 40.

I think we're on the same page. I was thinking more of the wire bridge in the middle of those you located. The metal arch is more akin to a long pipe rack and is a lot more stable laterally.

Here's the Street View placemark file.
