	For rehabilitation bridge jobs, steel armor is recommended when deck conditions adjacent to expansion area are not sound or a long service life is expected as in the case of a concrete overlay. Using steel armor should be based on actual field conditions and future expectations of bridge with consideration of cost also important.

	The number of movable deck joints in a structure should be minimized or eliminated in favor of the preferred and more commonplace integral bridge construction following the integral bridge maximum construction length limits given in [[751.14 Steel Superstructure#751.14.1.2 Girder Limits and Preferences\|EPG 751.14.1.2 Girder Limits and Preferences]] and [[751.22 P/S Concrete I Girders#751.22.1.4 Span and Structure Lengths\|EPG 751.22.1.4 Span and Structure Lengths]]. When deck joints are required, they should be avoided over roadways, railroads, sidewalks, other public areas, and at the low point of sag vertical curves.

	New and replacement bridges should be joint-free when possible. Redeckings should be made joint-free when possible; expansion joints should only be considered if it is structurally practical. Rehabilitation strategy should be the elimination of existing joints wherever practical.		New and replacement bridges should be joint-free when possible. Redeckings should be made joint-free when possible; expansion joints should only be considered if it is structurally practical. Rehabilitation strategy should be the elimination of existing joints wherever practical. Longitudinal expansion joints should be avoided and shall not be used without prior approval from the Assistant State Bridge Engineer.

	A closed sealed joint should be used wherever practical. Special challenges in utilizing these types of joint systems include addressing noncompressible debris that can be lodged in openings and snowplowing impacts.

Smithk: Per BR, revised increments for legs of shaped bars from ⅛” to ¼” due to upcoming move to new bill of reinforcing steel software which does not allow ⅛” increments. Revised various EPG details that showed ⅛” increments.
