In army bridge construction simulation, you have to deal with different heavy equipment, and build a bridge which connects your city to off road heavy traffic. You will not be required to buy and transport different building material from vendors, but instead only need to take concrete blocks to construction site from army base. In beginning levels, you have to be a transporter, and operate tower crane to load concrete blocks to mega army truck. In next levels, once you have proved your expertise in ultimate driving and transportation of construction material, your duties will change and will fill in with road building expertise.
