Here is an article on removing cement from a car's finish...
http://www.carwash.com/article.asp?IndexID=6635958
FWIW I would REALLY try to contact the public works department, or whomever was working on that bridge.. Likely this could be a COSTLY effort to remove that cement, and it might damage the finish of your truck.
A year or two ago I was driving my boat up the Milwaukee River when they started torch-cutting the MINUTE I was under the bridge. Sparks or hot metal fragments came down on the canopy and burned holes in.
I called the DPW and they reimbursed me for the cost of replacing the canopy.
I would suggest making a call tomorrow.

couple of my buddys live by a Lehigh Cement plant, and they used Vinegar to get it off there trucks, put it in a spray bottle and spray it on, let it soak, wash your truck like any normal wash and its gone. Works good for getting bugs and whatnot off your fenders down behind your tires too.

an old thread:

I would be REAL cautious about using lime-away...
Lime-away has phosphoric acid in it. I can't imagine that is good for a clear-coat.
Vinegar should be much better, but I'd be careful about letting it soak... I'd leave it there JUST long enough to let it work. Try just a short time at first, and if that doesn't work leave it a little longer. I'd experiment on a small spot only first.
Spray it off with the hose... If it starts to come loose you don't want to rub it into the paint as you wipe it off with a rag.

It never has hurt the paint for me. My dad hauled high grade lime(used to stablize soil) and it would stick to everything. Lime away always took it off, and we used it every week. One truck was not washed in 3 years, and I ended up getting on top of the sleeper with a gallon jug of muratic acid, and just poured it on. I though that it would remove the paint, but it seemed to do no damage!

go to your local ready mix supplier and get some acid. The acid we use does not damage anything on the trucks. I get dust on my pickup from time to time and if it sticks I simply spray a little acid on it and wash it off. We us Romix backset and Arrow Magnolia Rustcon. Either one works well.

I thought of the muriatic also but boy I'd sure want to test that on something that didnt matter first. I know it'll eat cement but clearcoat? And what if you have a little pit and it hits metal? Sounds risky, but might be one of those oddball things where you're just fine.
I've used it to etch concrete, and once on a toilet that, well I'll just say it worked really well and the porcelain was fine.

the acid they make for washing concrete trucks is designed not to hurt the paint, clearcoat, tires, windows, etc. I is not nearly as toxic as the old acids. I have used the products i mentioned early without any problems!
got it off today with a product called speedy clean a non toxic or corrsvie concrete disolver that and a little compound and wax it looks like new. thanks for the help.
