The word 赶到 is formed by combining the character 赶 (gǎn), which conveys the idea of hurrying, rushing, or chasing after something, with the character 到 (dào), which means to arrive at or reach a destination. Together, they conceptually merge into a single action that depicts moving with urgency or effort specifically to arrive at a particular place or point in time, thus creating the integrated meaning of "to hurry to arrive" or "to manage to get somewhere".
