Bridges & Concrete Structures

In COLAS CZ, a.s., we also focus on construction, repairs and reconstruction of both road and railway bridge structures. We also build steel and wooden bridges and footbridges as well as retaining walls, noise barriers, utility tunnels and structures made of waterproof concrete.

Our main field of work in this part of civil engineering deals primarily with bridges, which have a medium span up to 100 m. As for the material, there are many options we are able to build from scratch: RC bridges, prestressed concrete bridges, precast concrete bridges and steel-concrete composite bridges as well as steel and wooden bridges. We also offer refurbishment and modernisation works on existing bridge structures.

D11 - New bridge in Božanovská Street, Prague

The bridge over D11 Motorway carries the local road Horní Počernice - Běchovice.

Kácov bridge

The Kácov bridge project involves the construction of a new three-span road bridge with a total length of approximately 75 m over the river Sázava. COLAS CZ, a.s. built the new bridge to replace the existing structure which had been no longer suitable due to its poor condition, limitations of load capacity and unsuitable geometric parameters for the needed traffic crossing.

Patton Bridge in Plzeň

On May 2nd, 1973, a new bridge (nowadays called Patton Bridge after the late general Patton), over the river Mže, was put into operation. The bridge has relieved the traffic by deflecting it from the square into the direction of Karlovy Vary and Žatec.

Prague Ring Road - Chlumecká Street Overpass

The new bridges had replaced an obsolete overpass in the eastern part of the Czech capital.
