It's not Dodge bullets, especially in the main map. Even if you do die you just respawn and keep going.
I just ran accross the bridge twice, taking 0 damage both times.
The first time the only people pking were 1 guy with an AA12 and a few noobs shooting their trial handguns. The second time I didn't even encounter anyone until the end of the bridge which was one guy with a pbp who was shooting at a noob.
Also, bridge isn't the only access to south.
If you have any questions or concerns towards era, be sure to send me a message.Spoiler
How about travelling to new map extensions (like famous different landmarks of the world) using the airport?
