OMNNI was part of the design team for the mega-project on USH 41 to widen the corridor from four to six lanes. Project work included the preliminary and final structure design and plans for the bridge replacement on Mason Street over USH 41. The bridge is a 212-foot-long, two-span 45W” PPC girder bridge with significant aesthetic treatments. The bridge is supported on deep cast-in-place concrete abutments that extend about 300 feet north and south of the bridge along USH 41 with curved cast-in-place concrete retaining walls.
The project also included 1000 LF of mechanically stabilized earth concrete panel walls and 1500 LF of sheet pile retaining walls with concrete facing along the north side of Mason Street to separate the roadway from the southbound exit ramp and Mason Street sidewalk. Aesthetic treatments were incorporated on all walls and railings.
