Modernization of the railway line Sofia – Plovdiv
Sofia – Elin Pelin
.
Elin Pelin – Septemvri
.
Elin Pelin – Ihtiman
.
The project concerns the design of two concrete railway bridges on two tracks.
Bridge 30+217 km
- Consists of 6 middle spans with length of 30 m and 2 end spans with length of 27 m. The entire length of the facility is 234 m.
- The facility is situated in a horizontal curve with a radius of 1500 m on the left track in the direction Ihtiman and 1504 m on the right track.
- Reinforced concrete frame construction.
- One span of the structure consists of 8 precast concrete beams with a length of 22 m and a weight 35 tons.
- The beams are joined by cast in situ reinforced concrete plate.
- The substructure contains of cast in situ reinforced concrete abutments directly connected to the superstructure and mainstay.
- The foundation is provided by cast “hanging” piles with Ø1,2 m and length of 20 m.
- At both ends of the facility are provided dilatation joints.
- Behind the mainstay there is a retaining wall that takes the action of earth pressure.
Bridge 30+756 km
- Consists of 12 middle spans with length of 30 m and 2 end spans with length of 27 m. The entire length of the facility is 414 m.
- The facility is situated in a horizontal curve with a radius of 1500 m on the left track in the direction Ihtiman and 1504 m on the right track.

Preparation of Detailed spatial development plans and technical design for the project “Modernization of the railway line Sofia – Plovdiv reailway sections Sofia – Elin Pelin and Elin Pelin – Septemvri”: Section Elin Pelin – Ihtiman
Specific objectives of the modernization of the railway section Sofia-Elin Pelin and Elin Pelin – Septemvri, are improving safety of railway section, increasing speed along the railway section, increasing capacity and reduction of the environment pollution.
