Cardiff, Wales operates a public capital programme that funds roads, bridges and related infrastructure through council capital budgets and external financing. This guide explains how Cardiff Council sets priorities for road and bridge investment, how local bylaws and permit regimes affect contractors and developers, and where to find official applications and contacts for works on the highway.
