Bridge Expansion Joints
Bridge Expansion Joints, as shown in the photo, are designed to allow for continuous traffic between structures accommodating movement, shrinkage, temperature variations on reinforced and prestressed concrete, composite and steel structures. Bridge expansion joints also allow enough vertical movement to allow bearing replacement without the need to dismantle the bridge expansion joint. There are various types of Bridge Expansion Joints that can accommodate movement from between 30 to 1000 mm these include small movement expansion joints (XJS, JEP, WR, WOSd, and AC-AR), medium movement expansion joints (Etic EJ, Wd) and large movement expansion joints (WP, Etic EJF/SFEJ).

Famous quotes containing the words bridge, expansion and/or joints:
“It launchd forth filament, filament, filament, out of itself,
Ever unreeling them, ever tirelessly speeding them.
And you O my soul where you stand,
Surrounded, detached, in measureless oceans of space,
Ceaselessly musing, venturing, throwing, seeking the spheres to connect them,
Till the bridge you will need be formd, till the ductile anchor hold,
Till the gossamer thread you fling catch somewhere, O, my soul.”
—Walt Whitman (18191892)

—John Dos Passos (18961970)
“To round that shells elaborate whorl,
Adorning every secret track
With the delicate mother-of-pearl,
Made the joints of Heaven crack....”
—William Butler Yeats (18651939)
