Thanks I appreciate the help, I think I have to move on from here. Sorry I'm fairly new to this posting questions as such. Not meant to be a wild goose chase and I appreciate the feedback. Regards to all

Yep that's the bridge!

I don't have great photos.The bridge design is a single leaf Scherzer rolling lift bascule bridge https://www.google.com/maps/place/Saugatuck+River+Railroad+Bridge/@41.1194231,-73.3682815,15z/data=!4m5!3m4!1s0x0:0x3d73b2c5191324ff!8m2!3d41.1194231!4d-73.3682815...

What's the procedure for designing supports/platforms for machinery on a movable rail bridge?Is there a passage in AREMA? Sample calcs? Thanks

No I don't have a spreadsheet but one would be greatly appreciated.

What if there were two overhangs?

Does anyone know what's the deflection formula for a beam overhang one support for a triangular distributed load over the entire beam? Beam is supported by two supports.

It's Region 11. Bridgebuster, what is the limiting criteria for deflection? I found the NYC DOT Highway rules August 2016 edition and it says for plating and decking if the deflection is more than 3/4", heavier sections or plates or decking or intermediate supports shall be used.

Thanks I'm in NYC. I was told yesterday by a coworker that NYSDOT doesn't want plates down because there was a really bad motorcycle accident and the cyclist sued.

What is the deflection criteria for a temporary roadway plate?

Does anyone have a detail from previous projects of a curb ramp over a joint or where I could find one?

The plate in first link is about 3/8" thick?

And they're lukewarm to the thrie beam idea in that area.A coworker and I kind of proposed that.

I-95 and US-1 going to GWB

It's a limited access road that carries high speed traffic in NYC and it's average daily volume is about 280,000. The median varies from 18" to 3.5'.
