Form Fhwa 1629 is a design guide for the construction of culverts and bridges. The form is used to document the structural analysis and design of highway drainage structures in accordance with the AASHTO LRFD Bridge Design Specifications. Culverts play an important role in keeping our roadways clear, and Form Fhwa 1629 ensures that they are designed and constructed to withstand the demands of traffic. If you're responsible for designing or overseeing the construction of culverts or bridges, be sure to familiarize yourself with this form. It's essential for ensuring that your structures meet all safety requirements.
