Gurit UK (Newport, Isle of Wight, U.K.) reported on June 3 that the new composite Bradkirk Bridge, featuring materials and technology supplied by Gurit UK, was last week installed in just sixhours in Blackpool, U.K.  The bridge replaces an existing metallic bridge that was life expired.

The bridge was manufactured by AM Structures Ltd. for Network Rail and engineered by WYG and comprises of two 12m/29.4-ft spans and two flights of steps.

Each span features a fully molded composite monocoque structure and was manufactured using Gurit’s patented Sprint out-of-autoclave epoxy. Gurit’s Spabond 340LV and Ampreg 22 were also used for bonding, resulting in a virtually steel-free construction, with each span weighing only 1.6 tonnes/3,527 lb.

The new Network Rail structure, with a total scheme cost of £665,000, was installed by Birse Rail during a routine line closure overnight on May 17 and was completed within six hours. The bridge is expected to last more than 60 years and will be virtually maintenance free, with the exception of routine inspections and replacement of non-slip finishes and stair noses.
