<p>Opened in September of 2018, the Gathering Place is a spectacular 27-hectare (66 acre) public park located two miles from downtown Tulsa, Oklahoma and nestled along the eastern bank of the Arkansas River. This paper focuses on design and construction of a footbridge spanning across busy Riverside Drive to integrate the river into the park landscape.</p><p>As part of the park development the highway itself was transformed into an iconic feature. To meet this challenge, architectural considerations took an important role in the selection of the structure type for the new crossing, leading to the choice of a single-span, post-tensioned concrete box girder bridge with trapezoidal cross section. With a clear span of 43.7 m (143.5 feet) and a depth of only 1.2 meters (4.0 feet) the structure is exceptionally slender. A unique integral foundation system allowed the elimination of bearings, expansion joints, and abutment retaining walls, thus creating the impression of the bridge growing organically out from the landscape.</p><p>The paper touches briefly on the transformation of the urban environment with the development of the park and then discusses the challenges encountered during design and construction of the footbridge due to its great slenderness and unusual foundation system.</p>

Design And Construction

The wide and scientifically grounded use of gabion structures was restrained due to the lack of regulatory and methodological foundations and documents for the design and construction of these structures in road and bridge construction, in which technical requirements, design solutions, conditions and scope of gabion were worked out, systematized and formulated designs.It is very important to have a high-quality methodological and regulatory framework necessary to regulate the use of gabion structures, develop new, improve and expand the current standard solutions for strengthening the slopes of the subgrade, drainage devices and other structures, as well as in order to improve the quality of individual design of road and bridge structures using gabion structures, scientific, methodological and expert support of this design. So, the purpose of the work is to analyze domestic and international experience in the use of gabion structures in the construction industry in order to study calculation methods and technology for the construction of gabion structures. The object of research is gabion structures.The paper studies the theoretical and technological aspects of the use of gabion structures in road construction.The domestic and world experience of using gabion structures in the construction industry is analyzed. The advantages of using gabion structures in the development of design and construction solutions for the device and strengthening are considered.Methods for calculating gabion structures and their analysis are investigated. Due to this, the possibility of calculating gabion retaining walls with a height of more than 8 m was presented. Based on the calculation method, it was concluded that the use of gabion retaining walls of such a height requires lower costs than the devices of concrete and reinforced concrete retaining walls.
