Which Inland Marine policy covers bridges, tunnels, and instrumentalities of transportation?

The choice of Fixed Transportation as the correct answer is accurate because this type of inland marine policy specifically provides coverage for fixed structures that are essential for transportation systems. This includes important infrastructures such as bridges and tunnels, which are critical for facilitating the movement of vehicles and pedestrians. These structures are not only integral to the transportation network but also require specialized insurance due to their unique risks and the potential for significant loss in the event of damage or destruction.

Inland marine policies are designed to cover goods or property in transit and sometimes fixed locations that are not adequately covered by standard property insurance policies. Fixed Transportation policies fill this niche by addressing the needs related specifically to transportation infrastructure.

Other options, while related to transportation, do not specifically apply to the structures themselves. Mobile Equipment Insurance typically covers equipment that is movable but does not cover fixed structures. Transit Insurance and Property in Transit focus on the coverage for goods being transported but do not encompass the inherent risks associated with the fixed elements of transportation infrastructure like bridges and tunnels.
