Applies only when clearance is more than 10 feet at any point or entire distance between terminal abutments exceed 20 feet. 

Code 5222 applies to employers engaged in concrete construction in connection with bridges or culverts.  This operation involves the pouring of and finishing with concrete to conform to the shape of the culverts.  Includes the making, setting up or taking down forms, scaffolds, falsework, or concrete distributing apparatus, the manufacturing of concrete piles at the job location and the pouring of concrete into hollow steel piles.  This classification also applies to the concrete construction of lanes, sidewalks, and roadways on bridges.  The employer breaks up old concrete and lays down forms to hold the concrete.  After installing new steel reinforcement rods or mesh, new concrete is poured into the forms.

This classification does not apply if the employer pours concrete onto the existing road surface so as not to raise the height of the existing roadbed on bridges or add extra weight to the bridge with no new mesh or rods involved.
