A Bridge

I made a bridge that can cross busy streets to go to other places
Sketch

For this step, I sketched an outline of a bridge using lines and curves.
Extruding First Step

For this step, I selected some parts of the bridge and extruded them outwards to create a bridge shape.
2nd Sketch (Railing)

On this step, I started a new sketch on the sides of the bridge in the shapes of boxes for railings.
Extruding the 2nd Sketch Fail

I extruded the railings but they were off, so I had to modify it a bit, until it lined up perfectly.
Extruding 2nd Sketch Complete

I lined up the railings and made the railings nice and secure
Other Side of Railing

On this step, I change my view to copy the railing onto the other side, and sketched it.
Final Design

I finished the last sketch and edited the final product to look its best.
