yea. we had it designed with TX-70s but the min release strength of in the 7-8ksi range. Fabricator whine about having to leave the girders in the forms that long, so we bumped it up to TX-82s We told them we should have gone steel from the get go. I just went back and looed at the plans and it was 160 feet not 180.

i believe it was the longest LA has ever gone with concrete and one of the longest Texas had gone with them. (it was a joint project with ladotd and txdot)

126 for a 54 is long as well. All this was done before the LG girders were developed.

Check into the NRCS for cost share. 50% in some instances.

It won't help when the water is high but I would ford the by putting down concrete like they do river mats on the mississippi river.

Slope it out how you want and the put down concrete slabs that can be made at home or on site. Might be a doable compromise.

You could get some heavy cable and make a bridge that an ATV could cross for whenever the water in the creek is deep.

I did the cable bridge creek crossing but mine is only for foot traffic.

"Pour some footings "

Bridge abutments are poured on top of piles. Good luck.

You may want to look for a railcar that is to be scrapped and use it for a bridge. Several of these scrapping operations are around the US, I have seen railcar flats (bottom of the railcar) used as bridges. Should have some 75 feet long and possibly up to 90. Yes moving one is logistical challenge but they do work really well.

Yes this is a location to buy a railcar. Cars built prior to 1974 have a mandatory 40 life span and cannot exceed that without some for of recertification and approval by the FRA. This is why they are scrapped or sold for service where they do not go out of the main RR tracks. What is called captured service. Flat Cars like this are extremely durable and can hold a great deal of weight which makes them well suited for bridge service.

I have seen logging trucks cross over canal spans using a RR flat car bed. It was a long way down to the water too. Worked well until the truck missed the approach and kind of crashed between the bridge and edge of the bank. The heavy load of logs to the rear held the truck cab from falling into the canal. So much for that old truck. No one was hurt.
