Introduction

Sections 2 through 4 of this appendix provide descriptions of current bridge railing types acceptable for new construction, including the crash-test criteria used for testing and approved test level of the railing, as applicable.

Texas bridge railing type names use alphanumeric sequences, usually observing the following conventions:

The "nominal face of rail" is 1-ft. from the outside edge of bridge slabs, regardless of actual physical dimensions. Types T66, T224, T80TT, C412, and C66 railings are exceptions. Their "nominal face of rail" is set at 1.5-ft. from the outside edge of bridge slabs.
