Many highway bridges are built with expansion joints that can move back and forth. What is the reason for this?

• The bridge may need to be taken apart and put back together in a different location.

• The joints allow the bridge to be folded up, if necessary.

• The joints allow the bridge to expand and contract as temperatures vary.

• The joints allow engineers to expand the bridge and make it wider, if needed.
