Llandudno Flyover, Wales

Fast, bespoke drainage solution for prestigious Welsh bridge

Eccles began working closely with MWT Civil Engineering earlier this year after they were awarded a refurbishment project on the prestigious Llandudno Flyover in North Wales.

As the refurbishment work commenced the flyover had to be closed to allow safe working for reconstructing the road and replacing the bridge expansion joints.

This meant that design solutions had to be conceived, manufactured and supplied quickly to avoid delays and minimise public disruption.

Our AquaDeck team undertook drainage design work for both kerb drainage units for surface water removal and we proposed our new SubDrain sub surface drainage system to provide secondary sub surface drainage on the structure.

Chris Rothery, AquaDeck Project Director, met with the MWT construction team at their offices before the drainage works began:

“The design for our AquaDeck kerb drainage units was relatively straightforward, however the sub surface drainage layout proved to be more complicated because MWT were unsure exactly what they would find once the existing surfacing was removed.

“We agreed a couple of options on the SubDrain layout, fabricating a number of bespoke pieces so that MWT had flexibility on site once they began installation.

“We were conscious that the SubDrain channels were a critical path of works. Continuity and the avoidance of delays were key factors in this project; we were determined that MWT would not be delayed with the associated waterproofing and resurfacing works.”

Chris drove to site on a couple of occasions, including a Saturday morning visit to drop off additional special fabrications which MWT needed urgently – all part of the quality service and attention to detail that Eccles provide.

Thanks to this fast turnaround the drainage installation and final project was a resounding success, with the works even finishing earlier than had been anticipated.

The flyover and bridge is now fully waterproofed and ready to continue carrying traffic for years to come.

This is a huge credit to the MWT team and our thanks go to Mike Thomas and John Seed for the opportunity to work with them on this prestigious project.
