Challenge

Ahead of the 2012 Olympics, CTS Bridges has completed work on a new cycle ramp and bridge scheme over the River Lee in Bow, East London.

The project forms part of an 80km network of strategic routes to the Olympic Park that will serve to benefit local residents long after the finish of the games.

In total some 130m of ramps were installed. The inclined paths follow a zig-zag route up to the main bridge structure.

Solution

CTS’ experience and attention to design detail allowed them to identify the difficulties associated with such geometries and present alternative solutions to the client early in the design development.

The use of 3D modelling from an early stage also allowed CTS to resolve the difficult interfaces formed between adjoining ramps.

The restricted site necessitated installation of each of the 10m to 16m span sections by floating crane. Each span is supported on driven piles that were placed in the river by the main contractor May Gurney.

The pile connection detail that was developed satisfied the architectural aesthetic of concealed connections and eliminated on site welding requirements at the time of the main installation. Consequently the whole superstructure was installed by CTS Bridges in just 3-weeks.

The scheme incorporates varying length timber spindles made from sustainable ekki hardwood that form a naturally durable pedestrian parapet and visually soften the appearance of the steel vierendeel spanning structures.

Hi-Grip Plus non-slip overlay was specified by the architect in a colour that complements the rest of the scheme and provides safe surface for users.

Outcome

Located adjacent to a large junction on the busy A11, the link structure completes the River Lea river walk allowing pedestrians and cyclists to enjoy an uninterrupted traffic free route through London.
