## Steps
### Step 1: Navigate to Roadway Alignment
Navigate to **Bridge Geometry > Roadway Alignment** in the tree view.
### Step 2: Set Start Station
Enter **Start Station** as **0 ft**.
### Step 3: Open Alignment Editor
Click the **three-dots icon** on the cell and select **Editor** to define alignment properties.
### Step 4: Add Horizontal Segment
Click the **+ icon** next to **Horizontal** in the editor.
Choose **Straight** and enter a distance of **450** feet.
Quick Tip: Vertical Profile
You can edit the Vertical data such as grades and elevations of alignment in the Vertical tab.
### Step 5: Define Transverse Cross-Section
Click the **+ icon** next to **Transverse** to define the alignment cross-section at a specific station.
### Step 6: Configure First Station Cross-Section
Enter the cross-section parameters for Station 0:
| Parameter | Value |
| ---------------- | ----- |
| Station | 0 ft |
| Left Edge to PGL | 22 ft |
### Step 7: Add Section Component
Click the **+ icon** next to **At Sta 0** and enter:
| Parameter | Value |
| ----------- | ----- |
| Width | 22 ft |
| Left Slope | -2% |
| Right Slope | 2% |
### Step 8: Add Second Station Cross-Section
Click the **+ icon** next to **Transverse** again to define the cross-section at Station 450.
Enter the parameters:
| Parameter | Value |
| ---------------- | ------ |
| Station | 450 ft |
| Left Edge to PGL | 22 ft |
| Width | 22 ft |
| Left Slope | -2% |
| Right Slope | 2% |
### Step 9: Accept Changes
Click **Accept** to save the alignment configuration.
Quick Tip: Roadway Surface Display
If the 3D Bridge Alignment doesn't appear in the Graphics Window, click **Zoom Extents** on the right or enable **Show Roadway Surface** from Settings.
