The Águas Livres Aqueduct ("Aqueduct of Free Waters") is a historic aqueduct in the city of Lisbon, Portugal. It is one of the most remarkable examples of 18th-century Portuguese engineering. The main course of the aqueduct covers 18 km, but the whole network of canals extends through nearly 58 km.]]> http://virtualglobetrotting.com/map/47974/ http://virtualglobetrotting.com/map/47974/ Sun, 23 Mar 2008 17:56:01 -0500 http://virtualglobetrotting.com/map/47974/ 38.72963100 -9.17005800 <![CDATA[Canal crossing a canal on an aqueduct]]>

While building the Shrewsbury Canal the cheif engineer Thomas Telford's first tasks was to rebuild a stone aqueduct over the River Tern at Longdon-on-Tern which had been swept away by floods in February 1795. Telford's stone-mason instincts initially led him to consider replacing the original structure by another stone-built aqueduct, but the heavy involvement of iron-masters – notably William Reynolds - in the Shrewsbury Canal Company led him to reconsider. Instead, it was rebuilt using a 62-yard cast iron trough cast in sections at Reynolds' Ketley ironworks and bolted together in 1796. The aqueduct – the world's first large-scale iron navigable aqueduct (narrowly predated by a much smaller 44ft-long structure by Benjamin Outram on the Derby Canal) - still stands today, but is marooned in the middle of a field.]]>

The Pontcysyllte Aqueduct carries the Llangollen Canal over the valley of the River Dee, east of Llangollen in north Wales. The aqueduct is 307 metres long and it is constructed of cast iron troughs mounted on 19 masonry arches that carry the canal 38 metres above the river (note a narrowboat on the aqueduct). It was built by Thomas Telford and it was opened on 26 November 1805. Today it is a World Heritage Site.]]> http://virtualglobetrotting.com/map/19508/ http://virtualglobetrotting.com/map/19508/ Sun, 28 May 2006 14:26:18 -0500 http://virtualglobetrotting.com/map/19508/ 52.97069900 -3.09045000 <![CDATA[Remains of Catoctin Aqueduct]]>

Clifton Railway Viaduct (left) was built in 1846 over the river Irwell. The railroad is long gone but the great viaduct remains.

Clifton Aqueduct (right) took the Manchester, Bolton and Bury Canal over the Irwell. It was built in 1796. The canal is mostly dry although a little stretch of water remains where it goes under the railway viaduct. Parts of this canal are being restored.]]> http://virtualglobetrotting.com/map/15904/ http://virtualglobetrotting.com/map/15904/ Sun, 26 Mar 2006 04:42:25 -0600 http://virtualglobetrotting.com/map/15904/ 53.52744900 -2.31566400 <![CDATA[Skopskiot Akvadukt (Skopje Aqueduct)]]>

Skopskiot Akvadukt (Skopje Aqueduct)

From www.macedonia.co.uk:

The old aqueduct, built of brick and stone, is located at the end of the Skopje-Kacanik highway and is a monument from the 6th century AD. It supplied the city of Skupi with water from Mount Skopska Crna Gora. Some archaeologists assume that it had 200 arches, 50 of which still remain.

Also, from www.culture.org.mk:

The ancient aqueduct is located on the periphery of Skopje. It was built out of stone and bricks, with massive columns over which there are exactly 55 arcs.

There are different presumptions about the time of its construction. Some people claim that it is a Roman building and others that it comes from the Byzantine period. It is most likely that the aqueduct dates from the Turkish period, more precisely from the 16th century AD. The water was provided for the system from the mountain Skopska Crna Gora.]]>

Monocacy Aqueduct

The restabilization project, mentioned below and seemn in the thumbnail, was completed in May 2005.

From www.nps.gov:

The Monocacy Aqueduct is the largest of the eleven aqueducts erected along the C&O Canal, and is often described by many historians as one of the finest canal features in the United States. Ten of the eleven aqueducts remain as key features of the Chesapeake and Ohio Canal National Historical Park, which was designated as a National historical park in 1971. The Catoctin Aqueduct collapsed after its piers were gradually undercut and a flash flood took it down in 1972.

Construction of the Monocacy Aqueduct began in 1829 and was completed four years later. Three separate contractors labored on the immense stone structure, which was constructed for $127,900. The plan for the Monocacy Aqueduct, often referred to as C&O Canal Aqueduct No. 2, was for a stone masonry structure with a waterway of 19 feet at the bottom and 20 feet at the top. The towpath parapet wall is 8 feet wide and the upstream wall is 6 feet wide. Benjamin Wright drew the plans with 6 piers, 2 abutments and 7 arches, each with a span of 54 feet. The piers are 10 feet thick with pilaster at each end. The aqueduct is 438 feet in length. Much of the building material was large granite stone blocks quarried at the base of nearby Sugarloaf Mountain.

Following the 1972 Hurricane Agnes flood, the National Park Service and the Federal Highway Administration designed a steel banding system to stabilize the structure and installed a steel rod reinforcing system. The National Park Service and park supporters have long been concerned about the structural stability of the aqueduct and a major engineering evaluation is underway to determine stabilization needs and associated cost. The C&O Canal National Historical Park and its partners plan to undertake a major stabilization project for the aqueduct to ensure long-term sustainability for the structure. The project would provide for the removal of the steel banding support system and allow the visiting public to view the structure as originally constructed.]]>

Seen here extending from underneath the Francis Scott Key Bridge.

From oha.ci.alexandria.va.us:

The Alexandria Canal played a short, but important, part in the history of commercial navigation on the Potomac River. Congress granted a charter to Alexandria Canal Company on May 26, 1830. When completed, the Alexandria Canal crossed the Potomac River in an aqueduct bridge over 1,000 feet long between Georgetown and Rosslyn then ran on level ground seven miles to the edge of Alexandria terminating in a large basin. The Potomac Aqueduct Bridge, built under the direction of Major William Turnbull and Lieutenant Maskell C. Ewing, both of the U.S. Topographical Corps, was a large wooden trough supported by eight solid masonry piers, a major undertaking at the time. In 1845, the canal company completed the construction of the four lift locks at Alexandria which lowered canal boats approximately 38 feet to the Potomac River where they discharged their cargoes onto wharves or directly into sailing vessels.]]>
