CED7 Four Beam Bridge Expansion - Standard Specifications

Oct 23, 2026

CED7 four-beam bridge standard drawings establish design, detailing, and application requirements for bridges with 28' clear roadway and specified beam/deck slab configurations. The design engineer must clearly designate fixed and expansion bearings and separately schedule expansion joint opening sizes based on ambient air temperature, with maximum expansion length controlled per bearing detail sheets. Use is limited to strict conformance to listed designs; “special” and “non-standard” bridges are prohibited, and only conventional abutment and superstructure details are included.

FAQs

What must the design engineer designate in the CED7 bridge plans regarding bearings?

The design engineer must clearly designate all fixed and expansion bearings separately in the CED7 bridge plans.

How is the expansion joint opening schedule determined?

The schedule of expansion joint opening size must account for ambient air temperature at the time of setting the joint, using the temperature increments shown in the schedule.

Are “special” or “non-standard” bridges allowed under the CED7 standard drawings?

No. Fabricating or erecting “special” or “non-standard” bridges is strictly prohibited when using the CED7 bridge standard drawings.
