An aging three-sided cast-in-place (7-foot x 7-foot) box culvert constructed in 1946 under M-43, west of Grand Ledge, MI was compromised by degradational scour, which undermined its foundation and footings. M-43 is a critical roadway owned by the Michigan Department of Transportation (MDOT) that links industry, commerce, agriculture, and residents. The failing structure was identified through MDOT’s ongoing condition surveys of existing culverts and bridges. MDOT closed the road and specified a 12-foot x 6-foot precast concrete box culvert to expedite the replacement of the failing structure.
