62-514: The Division Street Bridge is an historic roadway and sidewalk stone arch bridge in Pawtucket, Rhode Island , carrying Division Street over the Seekonk River . The structure was built in 1875–1877 at a cost of USD $ 95,000. It is a nine-span stone and brick bridge with a total length of about 450 feet (140 m), making it the "finest and longest" stone arch bridge in the state. It is said to be

124-510: A symbolic icon of the unity of the two neighborhoods, which are divided by the river, coming together as the Town of Pawtucket. The bridge was listed on the National Register of Historic Places in 1983. Although it may be "functionally obsolete" relative to traffic patterns and in need of repairs, it is considered to be architecturally and historically significant. The Division Street Bridge

186-505: A deck arch bridge. Any part supported from arch below may have spandrels that are closed or open. The Sydney Harbour Bridge and the Bayonne Bridge are a through arch bridge which uses a truss type arch. Also known as a bowstring arch, this type of arch bridge incorporates a tie between two opposite ends of the arch. The tie is usually the deck and is capable of withstanding the horizontal thrust forces which would normally be exerted on

434-447: A number were segmental arch bridges (such as Alconétar Bridge ), a bridge which has a curved arch that is less than a semicircle. The advantages of the segmental arch bridge were that it allowed great amounts of flood water to pass under it, which would prevent the bridge from being swept away during floods and the bridge itself could be more lightweight. Generally, Roman bridges featured wedge-shaped primary arch stones ( voussoirs ) of

In the first compression arch bridges, a keystone in the middle of the bridge bore the weight of the rest of the bridge. The more weight that was put onto the bridge, the stronger its structure became. Masonry arch bridges use

The steps of the masonry may be trimmed to make the arch have a rounded shape.

1054-429: Is a nine-span stone and brick structure, with a total length of about 450 feet (140 m). Each of its spans consists of a segmented arch of about 50 feet (15 m) in length. The road bed is 27 feet (8.2 m) wide, and there are 7-foot (2.1 m) sidewalks on either side. The mean height of the bridge above the water is 45 feet (14 m). The piers of the bridge are constructed of coursed granite ashlar and

1116-660: Is architecturally significant as the longest stone arch bridge in Rhode Island and historically significant as a symbolic gesture to link and unify the two rapidly growing neighborhoods on Pawtucket Falls under the newly formed Town of Pawtucket. The bridge was listed on the National Register of Historic Places in 1983. Arch bridge Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge

1178-424: Is critical, but the recommended work is rehabilitation of the structure. The report estimates the cost of repairs to be US$ 9,834,000. A collection of reports dating back to 1995 lists the bridge as "functionally obsolete" for its current traffic requirements. A 2006 traffic report listed the bridge as carrying 21,900 vehicles daily. In 2007 the historic bridge saw an increase in traffic, as a heavy truck detour during

In some locations it is necessary to span a wide gap at a relatively high elevation, such as when a canal or water supply must span a valley. Rather than building extremely large arches, or very tall supporting columns (difficult using stone), a series of arched structures are built one atop another, with wider structures at the base.

The spandrels , the space between the arches, are filled with mortared granite rubble, and the arch barrels are constructed with an estimated 550,000 bricks. The original roadway was made of granite blocks , the seams of which were filled with tar , but this has been modified with modern asphalt paving and with the piers being modified with

1674-516: The 1906 annual report recorded US$ 15.82 for unspecified work. Though listed as only a footnote, repairs to the bridge were made in 1918. The Division Street Bridge was last rehabilitated in 1985, but it remains open under no restrictions after its inspection in May 2012. Data from the National Bridge Inventory lists the superstructure and substructure as in fair condition. The scour condition

The three elegant arches of the Renaissance Ponte Santa Trinita (1569) constitute the oldest elliptic arch bridge worldwide.

2046-420: The addition of reinforced concrete sheathing for the river piers. The iron walkways, produced by Crowell and Sisson, project over both the sides of the bridge with iron brackets. Constructed from 1875 to 1877 at a cost of USD $ 95,000 , the details of the bridge's construction and its architect are unknown. A contemporary account states that the need for the bridge was first proposed in 1871, but it wasn't until

2108-416: The arch and the deck is known as the spandrel . If the spandrel is solid, usually the case in a masonry or stone arch bridge, the bridge is called a closed-spandrel deck arch bridge . If the deck is supported by a number of vertical columns rising from the arch, the bridge is known as an open-spandrel deck arch bridge . The Alexander Hamilton Bridge is an example of an open-spandrel arch bridge. Finally, if

Many modern bridges, made of steel or reinforced concrete, often bear some of their load by tension within their structure. This reduces or eliminates the horizontal thrust against the abutments and allows their construction on weaker ground. Structurally and analytically they are not true arches but rather a beam with

This type of bridge has an arch whose base is at or below the deck, but whose top rises above it, so the deck passes through the arch. The central part of the deck is supported by the arch via suspension cables or tie bars, as with a tied-arch bridge . The ends of the bridge may be supported from below, as with

Trajan's bridge over the Danube featured open- spandrel segmental arches made of wood (standing on 40 m-high (130 ft) concrete piers). This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m-long (2,590 ft) long Puente Romano at Mérida .
