Roads & growth
Traffic is the civic argument in Mount Pleasant, and how much gets built is the argument underneath it. All 52 entries below name the responsible agency — Town, Charleston County or SCDOT — with the cost and the current status as that agency publishes it. Where a completion date has moved, both dates are shown, because a schedule that has slipped three times is itself the useful fact.
