The culvert cells (pipes or box units) should extend at least 300mm beyond rock fill. Discharge from the culvert should not cause excessive bed or bank erosion. The recommended design standard for temporary culvert crossings is presented in Table 1.
The design live loads applied to the top slabs of box culverts include the HL-93 truck and tandem loads for box culverts of any span length. For box culverts with spans of 15 feet or greater lane loads are also applied to the top slabs of box culverts. This practice is consistent with previous versions of the AASHTO Standard Specifications for Highway Bridges. [3.6.1.2.4] [12.11.2.1] Design

Hydraulic design Box culverts are commonly used as a conduit under roadways or railways. Hydraulic designs of such structures involve: • evaluation of peak design flow rate • selection of culvert shape • determination of operating condition of culvert, that is whether flow through the culvert is controlled by inlet or outlet conditions • check of outlet velocity (erosion or siltation
