Veresk bridge, also known as Pol-e Piroozi, is a historical bridge located in the northern part of Iran, in Mazandaran province. It was built during the reign of Reza Shah Pahlavi, the first king of the Pahlavi dynasty, and was completed in 1937.

The bridge is located on the route of the Trans-Iranian Railway, which connects the Caspian Sea to the Persian Gulf. It was built to replace an older bridge that had been destroyed by floods, and was designed by a team of Iranian engineers and architects. The construction of the bridge was a significant achievement at the time, as it involved overcoming a number of technical and logistical challenges, including the need to transport building materials to the site in a remote and mountainous area.

The bridge is a symbol of Iranian engineering and architecture, and is renowned for its beauty and technical sophistication. It has become a popular tourist destination, attracting visitors from all over the world who come to admire its graceful arches and stunning views of the surrounding mountains and valleys. The Veresk bridge is also an important landmark in the history of Iranian transportation and infrastructure, and serves as a testament to the ingenuity and creativity of Iranian engineers and builders.
