Widawska overpass

Map: Widawska overpass
Widawska overpass was erected during the S8 road construction. It provides collision-free intersection of the expressway and powiat road DP 1765E leading to Podłężyce and Zapolice. Loads are transferred to pillars by pot bearings. Total length of the bridge is 58,6 m with two spans 28 m each. The abutments and pier are founded on foundation piles of 1,5 m diameter and 18 m length each.

TYPE: road overpass
CROSSES: expressway S8
STRUCTURE: concrete
   Design: beam bridge
   Main girders: prestressed concrete beams
GEOMETRY:
   Number of spans: 2 (28,00 + 28,00 m)
   Total span lenght: 58,60 m

Viaduct over Ludowa street is a part of Sieradz bypass which was built simultaneously with Sieradz part of S8 expressway. It is a small one-span overpass with slab-beam structure. Underneath the bridge a short section of Ludowa street had been built in advance, providing the possibility of later construction. A very similar viaduct is located nearby, over Brzezińskiego street.

TYPE: road overpass
CROSSES: Ludowa st.
STRUCTURE: concrete
   Design: slab-beam bridge
   Main girders: reinforced concrete beams
GEOMETRY:
   Number of spans: 1 (19,90 m)
   Total span length: 21,00 m

The bridge provides a collision-free intersection of the bypass and Brzezińskiego street, leading to the Kłodzko Graveyard. A similar viaduct is located nearby, over Ludowa street.

Viaduct over Uniejowska st.

A small railroad viaduct is a big problem for Uniejowska street users. The Łódź Kaliska - Tuplice railway and the road intersect at two different collision-free levels, but the width of the road is reduced to a minimum. Thus the traffic has to be controlled by the traffic lights, only one way at a time. Moreover the height of the overpass is too small for some heavy trucks and they get stuck under the structure while trying to pass. Unfortunately, the widening of the viaduct would be difficult because of the structure of the abutments and intensive traffic under it.

   Main girders: I-beams

Railway overpass (Wojska Polskiego st.)

Map: Railway overpass (Wojska Polskiego st.)
Before the construction of the overpass all cars had to cross the railway through a level crossing, which was often closed due to heavy rail traffic. Analysis showed that the best solution is to build an overpass instead of existing level crossing. First actions started in 1980, and final works were made in 1983, after the overpass was opened. The structure is a continuous 19-span beam made from prefabricated elements (BSK beams). The outer spans are 17,9 m long, the center spans 18,3 m long. The north side of the bridge is provided with a pavement On the other side the pedestrians use a footbridge, as there is no pavement on the viaduct. It is worth mentioning, that due to rather negative experiences with such prefabricated beams most similar bridges in the country have already been demolished.
