# Superstructure Attachments

This section defines attachments mounted on the bridge deck including the roadway surface and barriers.

{% hint style="info" %}
**Navigation:** Superstructure Attachments

## Overview

Superstructure attachments affect both structural behavior and load distribution:

* **Roadway:** Defines lane geometry for live load influence calculations
* **Barriers:** Provide traffic safety and distribute wind forces
