US Threats Against Iranian Bridges: A Risk to Civilian Infrastructure and Economy

AI Summary
The US has threatened to target Iran's critical infrastructure, including its bridges, if it does not open the Strait of Hormuz. Five Iranian civilian bridges are at risk of US strikes, which could have severe consequences for the country's economy and civilians.

The United States has issued a threat to demolish Iran's critical infrastructure, including bridges and power plants, if Tehran does not open the Strait of Hormuz by early Wednesday. This move, described by President Donald Trump as 'Bridge Day', has raised concerns among experts, who warn that it could amount to war crimes.

Iran has approximately 300,000 bridges and technical structures, with only about 185 exceeding 100m in length. Five of the country's most prominent bridges are at risk:

1. Persian Gulf Bridge (Qeshm Island): A 3.4km-long unfinished bridge connecting Qeshm Island to Bandar Abbas, representing an investment of up to $700m. Destroying it would erase decades of national planning and impact Iran's hopes for a direct link to the island.

2. Lake Urmia Bridge (Shahid Kalantari Bridge): A 1.7km-long bridge connecting Tabriz and Urmia, cutting the driving distance between the cities from 240km to 130km. An attack could trigger an ecological disaster by dumping steel pilings and concrete into the shrinking Lake Urmia.

3. Sadr Multilevel Expressway: An 11km-long bridge in Tehran, supporting millions of commuters daily. An attack could cause massive urban casualties, destroy a key transport artery, and plunge Tehran's emergency evacuation systems into chaos.

4. Karun 4 Arch Bridge: A 378m-long bridge in Chaharmahal and Bakhtiari province, crucial for connecting Shahr-e-Kord and Izeh. Bombing it risks causing secondary damage to the hydroelectric facility, potentially leading to fatal flooding.

5. Ghadir Cable-stayed Bridge (8th Bridge): A 1,014m-long bridge in Ahvaz, spanning the Karun River. Destroying it would cut the city in two, choking off daily movement and emergency services in a province already battered by air strikes.
