The maximum skew angle for slab span bridges is 30°. With skewed spans, use shear keys that are 2 in. deep by 6 ft. wide and parallel to traffic. Form shear keys into the top of substructure caps in the middle of the caps. See the Cast-In-Place Concrete Slab Spans standard drawings for shear key details.

Break slab corners 1.5 ft. with skews more than 15°.

Minimum slab depths from Table 2.5.2.6.3-1 are guidelines but are not required.

Use a top clear cover of 2.5 in. Use 1.25 in. bottom clear cover.

Limit span lengths to approximately 25 ft. for simple spans and end spans of continuous units. Limit interior spans of continuous units to approximately 30 ft.
