Description
Chattanooga was a fast-growing city in the 1950s. To expand the city and allow more transport to cross the Tennessee River, it was decided to build several new bridge structures. The Olgiati Bridge, also called Ol 'Johnny , is a steel girder bridge over the Tennessee River in Chattanooga , Tennessee , built in 1959. It is named after the former mayor of the city, Peter Olgiati. The highway is US 27 [1] .
In that city, several bridges were erected at that time on the Walnut Street Bridge, the Market Street Bridge, the Veterans Memorial Bridge and Wilkes T. Thrasher Bridge [2] .
History
A few years before the idea of the Algati Bridge became the subject of public debate, the Wilks T. Thrasher Bridge was built in 1955 to provide an opportunity to cross the Tennessee River without congestion [3] . Peter Rudolph Oljati, born in Tennessee in 1901, was appointed to the city commission indefinitely, and then became mayor of Chattanooga, having been in office for 12 years. He supported the expansion of Chattanooga, and the construction of bridges was part of this plan [4] .
Construction
After constant efforts, in order to gain the approval of federal and state officials, $ 100 million was allocated to the mayor of Oldgiati for the development of the city. Based on the results of the implementation of the city development concept, Chattanooga became the first major Tennessee city to have a fully completed transportation system. The new bridge was built mainly due to overloaded and crowded bridges on Market Street and Walnut Street [5] . The construction project was approved in 1954, and construction began the following year. To begin the construction process, it was necessary to demolish about a thousand buildings, and relocate about 1,400 families. The bridge was opened for traffic in 1959. The bridge was originally called the Chedr Street Bridge , but was soon renamed the Oldgiati Bridge [1] . The bridge is constructed of I-beams, which consist of steel plates placed together to hold the bridge. It is known that steel bridges are more expensive, but their construction is much more efficient and safer [6] .
Reconstruction
Starting in February 1999, the Oldgiati Bridge was expanded from four to six lanes. This was achieved by additional expanding steel beams to the bridge supports. The reconstruction project, after repeatedly failing to meet the deadlines, was completed in February 2003 [7] .
In 2011, the City Department of Transportation announced a plan to add two more lanes to the bridge. The groundwork for increasing the number of lanes was already made in the first expansion project. A new reconstruction of the bridge began at the end of 2015, and is expected to be completed by 2019 [8] .
