Engineer outlines Weiss Road Bridge plan to limit disturbance, avoid FEMA permitting

Todd Baldwin, the project engineer, briefed the board on progress for the Weiss Road Bridge replacement. After evaluating precast culvert and traditional span designs, Pennoni’s current proposal favors a 55‑foot‑wide precast Conspan arch culvert combined with lowering previously developed vertical roadway geometry by approximately 1 foot. Baldwin said the revised concept reduces construction disturbance, passes events up to the 5‑year event without roadway overtopping and is designed to keep the 100‑year event water surface elevation change to less than 1 foot — a measure intended to avoid FEMA permitting requirements.
