What country are both the Dunans Castle and Dunans Bridge located in?
Scotland
Dunans Castle
Dunans Castle is a historic structure located in Glendaruel, on the Cowal peninsula, Argyll and Bute, Scotland.
 The property is owned by Charles and Sadie Dixon-Spain.
 A property at Dounens was shown on maps in 1590; Dunans House was elaborated into its present mock castle form in 1864.
 Once part of a much larger estate the property presently includes 16 acre of ground and in 2001 was ruined by fire.
Dunans Bridge
Dunans Bridge is a category A-listed structure, designed by Thomas Telford.
 It is located at Dunans Castle on the Cowal peninsula in Argyll, Scotland.
 It was built for John Fletcher of Dunans, to commemorate the battle of Waterloo.
 The bridge was completed in 1815, and predates the 1864 elaboration of Dunans House by Kerr into a Franco-Baronial "castle".
 The three-arched rubble construction is considered internationally important as it is the only extant bridge of this type.
 It stands over 15 m from the river bed and has been voted one of Scotland's ten best bridges.
 It was built to replace the now destroyed "swing bridge".
 Though it is of a kind often constructed by Telford, the three arches, gargoyles and eight hexagonal piers, as well as its sheer height 16 m , make it unique.
Marion Street Bridge
The Marion Street Bridge is an automobile bridge located in Salem, Oregon, United States.
 It spans the Willamette River to connect Salem and West Salem, and acts as a conduit for Oregon Route 22.
 The bridge carries vehicular traffic one way westbound.
 Traffic includes two lanes that flow onto the bridge from Marion Street, vehicles turning right from Commercial Street, and traffic from a quarter-loop on-ramp from Front Street that was added in 1981.
 Construction began in December 1952 and the bridge opened in 1954, after taking nearly three years to complete.
 The bridge was built to complement the Center Street Bridge, which switched from two-way traffic to eastbound-only, later expanding to four lanes in 1982.
 At the time of its opening, the Marion Street Bridge was the longest bridge of its type west of the Mississippi River. EJP County Line Bridge
The EJP County Line Bridge is a Camelback pony truss bridge located near Hyattville, Wyoming, which carries Big Horn County Road CN9-60 across the Nowood River.
 The bridge was built in 1917 by the Monarch Engineering Company.
 As the bridge was originally thought to connect Big Horn and Washakie Counties, the two counties split the cost of the bridge, with each paying for one abutment and the two splitting the cost of the superstructure; this is the only recorded case of two Wyoming counties purchasing a bridge in such a way.
 Further surveys determined that the bridge is actually located entirely within Big Horn County.
 At 102 ft long, the bridge is the longest Camelback truss bridge in Wyoming. Zhangjiajie Glass Bridge
Zhangjiajie Glass Bridge (also called Zhangjiajie Grand Canyon Glass Bridge, ) is a bridge located in Zhangjiajie, China, above the Wulingyuan area.
 The bridge, built as an attraction for tourists, is glass-bottomed and is transparent.
 It is the longest and tallest glass bottomed bridge in the world.
 The bridge, opened to the public on August 20, 2016, measures 430 metres in total length and 6 metres in breadth, and is suspended about 260 metres above the ground.
 The bridge spans the canyon between two mountain cliffs in Zhangjiajie National Forest Park in China's central Hunan province.
 As per the design, the bridge can carry up to 800 visitors at a time.
 The bridge was designed by Israeli architect Haim Dotan. Blackburn Point Bridge
The Blackburn Point Bridge is a historic swing bridge located near Osprey, Florida, United States, that is listed on the U.S. National Register of Historic Places.

 The bridge crosses the Lugton Water a short distance northwest of Eglinton Castle (grid reference [ NS 3206 4224] ) and was named after the Eglinton Tournament of 1839.
 The castle and surrounding grounds were once home to the Montgomerie family, Earls of Eglinton and chiefs of the Clan Montgomery. Oquawka Wagon Bridge
The Oquawka Wagon Bridge is a covered bridge located 2.5 mi south of Oquawka in Henderson County, Illinois.
 The wooden bridge was built in 1866, replacing an earlier bridge called the Eames Bridge; the bridge structure cost $2,125, while its stone abutments cost $2.40 per perch.
 The bridge carried a road over Henderson Creek until 1935, when the state government moved the roadway; in the following year, the bridge became a pedestrian bridge, and the state opened a picnic area in its vicinity.
 The bridge was added to the National Register of Historic Places on February 24, 1975. Qingchuan Bridge
The Qingchuan Bridge () is an arch bridge located in Wuhan, People's Republic of China.
 It is the fourth bridge on the Han River, the third motorway bridge (provisional name being "Third Jianghan Bridge") and also the "Rainbow Bridge" due to its shape and red color.
 The bridge has a span of 280 m (919 ft), with a full length of 989.75 m .
 The construction of this bridge begins on Dec 20, 1997, and completed in 2000, which started revenue service to the public.
 It has four lanes, connects Yanhe Ave in Hankou with Hannan Rd in Hanyang.
 It used to be a tolled bridge, but after the implementation of electronic toll collection in Wuhan, the toll plaza was razed. Choluteca Bridge
Choluteca Bridge, or Carías Bridge, is a suspension bridge located in the city of Choluteca, Honduras.
 It is an emblem of the nation and the city where it is located.
 It was built between 1935 and 1937 by the United States Army Corps of Engineers using US and Honduran capital for the construction of the road named Panamericana.
 The bridge's importance is not simply a matter of size.
 The Choluteca Bridge is 300 meters long, but it isn't the longest in the country or even in the city—there is another bridge in Choluteca called The Bridge of the Rising Sun, which is 484 meters long.
