LONG SPAN TIMBER BRIDGE

This article describes the design and construction of the footbridge built across the a406 South woodford to barking relief road in the eastern suburbs of London. The bridge is of laminated timber construction and has a clear span of 30 m across the new road, so that it is one of the longest timber footbridge spans in the UK. It provides direct access for golfers between the ilford golf club and part of its golf course; its ramp steps are provided with wedges with a slope of 1:3 to facilitate the passage of golf trolleys. To make the bridge durable, hardwood was chosen for all structural timber members and stainless steel was specified for all structural fittings. 80 cm sq reinforced concrete columns with a 2 m sq mushroom head were chosen as the supports for the main span. The bridge decks were designed to carry a basic live load of 5 kn per sq m. Heavy duty acme floor panels were chosen for the strong bridge deck surfacing. The main section and two ramp sections were delivered ready assembled to the site and lifted into position by a 120 tonne capacity mobile crane.
