Innovative Solutions for the M6 Toll: Transforming UK Infrastructure with Reinforced Earth®

The construction of the M6 Toll motorway, the UK’s first privately operated tolled motorway, required an innovative approach to deliver a reliable alternative to the congested M6. Spanning 27 miles northeast of Birmingham, this ambitious project included 39 bridge abutments and several retaining walls along the route.

Geoquest was tasked with designing and supplying these critical structures. Using Reinforced Earth® for bridge abutments proved highly effective, eliminating the need for piles or foundation improvements, reducing costs, and accelerating the construction timeline.

The joint venture CAMBBA (Carillion, Alfred McAlpine, Balfour Beatty, and Amec) selected Geoquest for their expertise and ability to deliver materials on a large scale. In total, Geoquest supplied 23,000 m² of precast concrete facing panels and over 500,000 metres of galvanised steel reinforcing strips. By leveraging its international resources, Geoquest met the project’s tight deadlines while maintaining the highest quality standards.

This project highlights the efficiency and sustainability of Geoquest’s solutions for large-scale infrastructure.
