LOADING REQUIREMENTS

• All bridge structures shall be designed for an HS25 loading or the alternate military loading, whichever produces the greatest stresses and live load deflections, unless otherwise stated in this manual. Figure 301 illustrates the HS25 truck and lane loadings.

• All bridges shall be designed for a future wearing surface (FWS) of 60 psf .

• All steel structures shall be designated as Case I or Case II as defined by AASHTO for fatigue design.

• Bridge structures on LPA projects shall be designed to the same loading requirements as traditionally funded projects except an HS20-44 loading may be used in lieu of the HS25 ] loading.
