the abutments at either end of the bridge anchor the arch so that it will not collapse, the weight of the arch is supported by the abutment on either end
A structure for resisting the pressure of water against a bridge. It supports or receives the thrust of part of the arch of the bridge. It absorbs the tensions. It receives the arch at the end of a brdge

An abutment is a structural support that connects and transfers loads from a bridge or arch to the ground, typically found at the ends of a bridge span. In contrast, a firewall is a protective barrier designed to prevent the spread of fire between different sections of a building or between buildings. While abutments are primarily concerned with structural integrity, firewalls focus on safety and fire containment.
because of the support of the circles
Arches are among the oldest forms of structural support. Unlike beam bridges, arch bridges are curved. The arch carries the weight outward along the curve to the supports on each end of the bridge, called abutments. The abutments carry the load and stop the bottom of the bridge from spreading out.
Because it has more support in its arches.

The brooklyn bridge is not a arch bridge
A bridge pier is a vertical structure that supports the bridge's superstructure and transfers loads to the foundation, typically found between spans. A pylon is a taller, often decorative structure used to support cables in cable-stayed or suspension bridges, providing both structural support and aesthetic appeal. An abutment is located at the ends of a bridge, supporting the ends of the bridge span and connecting it to the ground or earth embankment, resisting horizontal forces and stabilizing the structure.
You have to support the structure (the actual arch) using a wooden form up to the point where you insert the keystone, after which the arch will be self supporting.
In architecture, an abutment helps to support an arch. While a pier is a seaside stilted structure extending from the beach a little way out to sea. A pier may have buildings on it offering entertainment, and amusement arcades, to the visiting public - a common feature of many seaside resorts.
