  4. Rettew Mill Road Bridge Replacement

    Keller’s Covered Bridge, the original single-lane single-span Burr-arch wooden truss carrying Rettew Mill Road over Cocalico Creek, is a beautiful historic structure, but its 5-ton weight restriction, limited vertical and horizontal clearance, and insufficient sight distance prohibited it from adequately meeting modern-day transportation needs. Ephrata Township needed to replace this bridge in order to significantly…
