4 rail bridge rail with modified pedestrian fencing
4 rail bridge rail consists of 2 runs of 6 X 6 box beam with a run of 5 X 3 box beam both above and below the 6 X 6 runs.
This bridge is an example of a standard 4 rail bridge with no brush curb and no snow fence.
Each bridge post is anchored to the bridge and each piece of bridge rail is then fastened to each post on the bridge.
In this picture you can see the standard transition of a 4 rail bridge into guide rail. Notice how the top 5 X 3 rail terminates with a kickdown while the bottom terminates with a flareback.
Here is another view of the transition of a 4 rail bridge. Notice how this is a non-standard design because it uses a flareback on the top rail instead of a kickdown.
This picture shows an example of a 4 rail bridge on a brush curb to allow for the sidewalk. This bridge also has a snow fence made possible by a larger base plate on the post and a piece of pipe.
