Bridges Expansion And Contraction
Bridges with total temperature movement expansion plus contraction of in which typically corresponds to a bridge length of about 150 ft or less are not.
Usually expansion joints should be no farther apart than 2 to 3 times in feet the total width of the concrete in inches So for a 4 inch thick concrete slab expansion joints should be no more than to 12 feet apart.
