Fabrication & Installation of two steel footbridges

Beaver Bridges were awarded this project by Walters UK in December 2024 to fabricate and install two Warren Truss Footbridges over the river Cothi and river Tywi, which form part of the Tywi Valley Path Scheme. The Tywi Valley Path is a 16.7 miles traffic free path through one of the most scenic areas of Wales, running from Llandeilo to Carmarthen.

Bridge installation

Tywi Footbridge is 57 metres long x 4 metres wide clear span, steel hollow section framework with UB cross supports to deck area, steel angle diagonal bracings steel deck and steel parapets. Prior to our arrival on site the foundations including pockets for bearings were installed on site and a crane pad constructed. The bridge was delivered to site in 3 sections. Each section was lifted onto temporary stools/blocks and bolted together. Once complete, a series of loose bracings were installed to the underside of the bridge deck. The bridge was then lifted into its permanent position using a road mobile crane.

The bridge also included installation of approach ramps to both the north and south side, 50 metres long x 4 metres wide clear span. Prior to our arrival on site the foundations including pockets for bearings or cast in anchors were installed on site and crane pad was constructed. The ramps were delivered to site in 7 sections and 10 columns. The columns were installed first, then each ramp section was lifted onto the columns.

Concept to Completion

Cothi Footbridge is 63 metres long x 4 metres clear span with the same installation process followed as was used on Tywi Footbridge. No ramps were required on this footbridge. Both bridges and the ramps were fabricated at our factory in Wigan and delivered to site on 11 of our in-house vehicles under police escort.

Despite tough weather conditions, our in-house site team showed outstanding focus, dedication and technical ability to deliver these bridge installations safely and efficiently. These bridges are vital for completing the Tywi Valley Path, linking historical sites and natural beauty for visitors.
