Street Closures: Diagonal Diverter

Diagonal diverters are barriers placed diagonally across an intersection, blocking through movement; they are sometimes called full diverters or diagonal road closures. These types of street closures are most appropriate for neighborhood areas with grid network streets where cut-through traffic is a significant problem.
