This postcard from Daniel depicts two span-, 280 ft. long Dummerston Bridge, built by Celeb B. Lamson in 1872. It is Vermont's longest covered bridge and historically one of the most important of its in United States. This bridge carries East-West Road over the West River.

Postcard from Joyce. She lives in a small town near Arnhem and Nijmegen, which is actually the middle of Netherlands. On this card Joyce wrote me a good quote, said by John Lennon: "Life is what happens to you while you're busy making other plans". So true..

Krymsky Bridge or Crimean Bridge is a steel suspension bridge in Moscow popularly known as a favourite place for suicides. The bridge spans the Moskva River 1,800 meters south-west from the Kremlin and carries the Garden Ring across the river. The bridge links the Crimean Square to the north with Krymsky Val street to the south. The nearby Moscow Metro stations are Park Kultury and Oktyabrskaya.
The existing bridge was completed on May 1, 1938, as part of Stalin's ambitious reconstruction of downtown Moscow. Designed by engineer V. P. Konstantinov and architect A. V. Vlasov, it is the fourth bridge on this site and the only suspension bridge in all of Moscow.

Postcard sent by Kuang with the view the Black Dragon Pool in Yuquan Park (Jade Spring Park), China.

The Black Dragon Pool is a famous pond in the scenic Jade Spring Park (Yu Quan Gong Yuan) located at the foot of Elephant Hill, a short walk north of the Old Town of Lijiang in Yunnan province, China. It was built in 1737 during the Qing Dynasty and offers a spectacular view on the region's tallest mountain, Jade Dragon Snow Mountain, over its white marble bridge. The park features several smaller temples and pavilions:
* The Moon-Embracing Pavilion, which was originally built in the late Ming Dynasty. The current structure is a reproduction from 1963 after a fire in 1950.
* The Dragon God Temple (Longshen Temple) was constructed by local Naxi people in 1737 and is located to the east of the park. It was given the name Dragon God of Jade Spring by Emperor Qianlong of the Qing Dynasty in the same year.
* The threefold overlap Five-Phoenix Tower (Wufeng Tower) was built during the Ming Dynasty (1601), and today located at the north end of the park. The tower was originally situated at the Fuguo Temple, which is 30 kilometers to the west, but was moved to Jade Spring Park in 1979.
The park is further home to the Dongba Culture Research Institute and the Dongba Culture Museum.

This postcard shows The Tacoma Narrows Bridge after the wind-induced collapse in November 1940 and how nice it looks now:) Sent by Bob from Washington State (USA).

The Tacoma Narrows Bridge is a pair of twin suspension bridges in the U.S. state of Washington, which carry State Route 16 across the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula.
The original Tacoma Narrows Bridge opened on July 1, 1940. It received its nickname "Galloping Gertie" due to the vertical movement of the deck observed by construction workers during windy conditions. The bridge collapsed into Puget Sound the morning of November 7, 1940, under high wind conditions.
No human life was lost in the collapse of the bridge. However, a small dog perished after it was abandoned in a car on the bridge by its owner, Leonard Coatsworth, and by another man, both of whom were bitten by the terrified dog when they attempted to remove it. The collapse of the bridge was recorded on 16mm film by Barney Elliott, owner of a local camera shop, and shows Leonard Coatsworth leaving the bridge after exiting his car. In 1998, The Tacoma Narrows Bridge Collapse was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant." This footage is still shown to engineering, architecture, and physics students as a cautionary tale.
The current westbound bridge was designed and rebuilt with open trusses, stiffening struts and openings in the roadway to let wind through. It opened on October 14, 1950, and is 5,979 feet (1822 m) long — 40 feet (12 m) longer than the first bridge, Galloping Gertie. Local residents nicknamed the new bridge Sturdy Gertie, as the oscillations that plagued the previous design had been eliminated. This bridge along with its new parallel eastbound bridge are currently the fifth-longest suspension bridges in the United States.
