Abrégé

An arch bridge system including first and second side walls, a foundation, and arch beams. The first and second side walls each include side wall sections supported by the foundation and aligned along the width of the system. Adjacent side wall sections form a column therebetween that defines an interior void extending along a height of the column. A first end of each arch beam is supported at the first side wall at an upper portion of one of the columns and a second end is supported at the second side wall at an upper portion of another one of the columns. Each interior void has reinforced concrete forming cast-in-place columns defining rigid, fixed, monolithic connections between the foundation, the first and second side walls, and the plurality of arch beams. A method of producing an arch bridge system is also disclosed.
