More　than　half　of　the　global　population　now　live　in　urban　areas　and　more　high-density　cities　are　emerging,　where　living　with　the　constant　noise　of　moving　traffic　can　negatively　impact　the　health　and　well-being　of　residents.　Despite　recent　efforts　to　repurpose　urban　roads　into　public　spaces,　large　transportation　corridors　remain　a　pervasive　feature　of　urban　landscapes.　In　this　chapter,　we　propose　a　soundscape　approach　to　enhance　the　sound　quality　of　highway　environments　in　high-density　urban　areas　by　utilizing　the　leftover　roadside　space　to　reconnect　communities　and　establish　green　spaces　for　wildlife.　By　deploying　noise　reduction　techniques,　introducing　positive　sounds　into　the　environment,　and　integrating　visual　elements　with　soundscape　solutions,　this　approach　seeks　to　create　pleasant　experiences.　The　authors　also　offer　a　template　for　a　mainstream　design　process　that　creates　place-based　frameworks　for　integrating　soundscape　approach　into　urban　design　projects　and　community　decision-making.　By　tailoring　solutions　to　the　specificities　of　social　and　physical　context,　this　approach　has　the　potential　to　mitigate　the　negative　impacts　of　noise　pollution　on　public　health　and　quality　of　life　in　high-density　urban　areas.　©　2024　selection　and　editorial　matter,　Peng　Du,　Kheir　Al-Kodmany,　and　Mir　M.　Ali;　individual　chapters,　the　contributors.
