Project details

Brijesta Viaduct is an integral part of the Mainland - Pelješac Bridge project with access roads on D8 and D414. The total length of the viaduct is 134m and consists of seven spans between 17m and 20m long. The foundation of the columns of the Brijesta viaduct was designed on wells. The columns are of the I-section shape with external dimensions of 1.5x4.0 m, with an extension at the top to support the bearings. The height of the columns is from 6.15 m to 18.72 m. The superstructure of the construction is a monolithic reinforced concrete slab made on site over seven spans, inserted in 4 middle columns and supported by elastomeric bearings on the end columns and abutments. The slab has a constant thickness of d=110 cm, and ends at the edges with side cantilevers 2.55 m long, with a variable thickness of 25-50 cm. The transportation facility consists of two traffic lanes 2x4.05 = 8.1 m and two pedestrian paths with curbs 2.0 m wide, i.e., a total width of 12.10 m on most of the viaduct, while, at the end, towards the U7 abutment, the road widens so that the total width of the structure is 15.65 m. The works started in November 2021 and were successfully completed before the opening of the Pelješac Bridge in July 2022.
