Motorways are soundproofed using a combination of techniques, including the construction of noise barriers, the use of sound-absorbing materials, and strategic landscaping. Noise barriers, often made of concrete or wood, are erected alongside the road to block and deflect sound waves. Additionally, features like earth mounds and dense vegetation can help absorb sound. Pavement materials designed to reduce tire noise also contribute to minimizing overall traffic noise levels.
