Thanks for the report. The issue appears around the 33mins mark.

Edit1: With the Developer Overlay tools, I can`t see any obvious reason why they behave this way.

In this case it is the structures/bridge_hele which has health (and it gets reduced) and resistance. Both of which it should not have.

The template file is called: ​bridge_hele.xml
The actor file is called: ​bridge_edge_hele.xml

'Stan' suggested:

I think there is a template for that stone bridge while we should just use the actor.

After changing the .xml file of the map, the problem no longer occurs.
​public/maps/skirmishes/death_canyon_2p.xml

Current:

		<Entity uid="3452">
			<Template>structures/bridge_hele</Template>
			<Player>0</Player>
			<Position x="580.9596" z="517.5047"/>
			<Orientation y="2.35621"/>
		</Entity>
		<Entity uid="3453">

			<Player>0</Player>
			<Position x="568.75495" z="529.73041"/>
			<Orientation y="-0.77804"/>
		</Entity>

Changed:

		<Entity uid="3452">
			<Template>actor|props/special/eyecandy/bridge_edge_hele.xml</Template>
			<Position x="580.9596" z="517.5047"/>

In 25972:

Fix AI attacking some bridges.

Our bridges are nothing more than actors, so using one is correct.
We also delete the template files to prevent others from making the same mistake (if someone encountered and fixed the bug in a mod they have modified templates anyway).
