An arched culvert includes a first foundation having a top surface with a plurality of first reinforcing members upwardly projecting therefrom. A first arch includes a body having an arched interior surface and an opposing exterior surface extending between a first end and an opposing second end, the first end of the first arch being positioned on the top surface of the first foundation adjacent to the first reinforcing members. A first opening extends through the first arch between the interior surface and the exterior surface at the first end thereof. A first locking wall is formed on the top surface of the first foundation so that at least a portion of the first reinforcing members are embedded within the first locking wall and the first locking wall extends along the exterior surface of the first arch and into the first opening of the first arch.
