Recycled plastic bridge: sustainable! truly!!


An innovative new construction project has seen Wales achieve a European first in the construction sector.

A 90-foot thermoplastic bridge - made entirely from recycled materials - has been used to span the River Tweed at Easter Dawyck in Peeblesshire.

The bridge, which is made 100 per cent from re-used plastic weighs 50 tonnes and is capable of supporting traffic.

Vertech, which was responsible for the technology that underpins the project and managing subcontractors, said that the unique approach makes for maintenance-free, sustainable construction.

Green Bridge


The Tennant Avenue Bridge is a typical overpass that one may see throughout the United States. Its construction wasn’t unique; that is, no changes were made to its construction schedule to compensate for the reduced carbon footprint. The carbon footprint was reduced 25% compared to traditional mixes and may well have been further reduced. The specifications by which the concrete mixes were allowed to be used represent a dramatic change that provides a glimpse into the future sustainable design and construction of the infrastructure
