The reinforcement cage of a pier at an under-construction elevated road toppled onto a moving car at a Thane bridge, damaging its front windshield. A woman driver narrowly escaped without injuries, the police said.

While the reinforcement cage is technical for laypersons, it is important to understand that a reinforcement cage of a pier may also be called a pier cage and is a cylindrical or rectangular skeleton made of steel reinforcing bars placed inside a concrete pier or drilled shaft before the concrete is poured.
