One of Europe’s most advanced highway bridges

The West Mill Bridge in Oxfordshire, UK is one of Europe’s most advanced highway bridges:

Fiberline construction profiles in plastic composites were used for the load-carrying beams, the side panelling as well as the bridge deck itself. And what is more, the plastic composite profiles have the same load-carrying capacity as similar highway bridges in steel and concrete.


  • The ASSET profile used for bridge deck
  • Square profiles reinforced by carbon fibres used for load-carrying beams
  • Special profiles used for side panelling


  • Short construction phase and quick installation on site
  • Resistant to water, salt and frost
  • Long service life with minimum maintenance costs
  • Low operation costs and less traffic problems in the construction phase as well as in the entire service life of the bridge

Dimensions and technical data:

  • Span 10 metres, width 6.8 m
  • Total weight 37 t, the load-carrying beams and the bridge deck only weighs 12t
  • Carrying capacity for vehicles up to 46 t with an axle load of 13.5t
  • All load-carrying elements are made of polyester, glass and carbon fibres
  • Weight of bridge deck: 100 kg/m2

The West Mill Bridge in Oxfordshire was fabricated at a temporary site factory at the side of the bridge and was lifted into position in under 30 minutes.

The West Mill Bridge only requires minimum maintenance. Composite materials have a long service life, which is considerably longer than that of e.g. concrete and as the bridge deck is resistant to water and salt, a waterproof membrane is not necessary. Only the wearing surface of the road and the construction joints require periodically maintenance.

  • Each of the four main supporting beams are constructed of four profiles reinforced by glass and carbon fibres and glued together. Dimensions 520 mm x 480 mm.
  • The decking system of 34 ASSET bridge deck profiles glued together are positioned and glued onto the supporting beams. The profiles can be mounted on concrete beams as well as on steel beams.
  • The side panelling consist of maintenance-free and corrosion-resistant 550mm high composite profiles.
  • The edge beams, footpath and the two crossbeams at each end of the bridge are made of concrete, whereas the crash barrier is made of steel.
  • The wearing surface is made of polymer concrete, but asphalt is also an option.
