Thanks JDM, boom lift sounds about right to me.
Need a trucker now to tell up the normal height of a empty flat bed 18 wheel trailer. Put the boom lift on top in traveling mode. That's a tall unit, but don't know the height of a tractor trailer unit in normal mode.

Too bad they didn't dig out the road bed and pave before construction of the overpass bridge. Looks like more than 14' 5" was needed in this case.
