Greystone Footbridge, Huyton

Modern, eye-catching cable-stayed bridge spanning the M62 between Junctions 4 & 5
Knowsley Council
October 2015
25 Weeks


EWCE was appointed to replace an existing footbridge over the M62 motorway with a new combined footbridge and cycleway.

The proposed design of the new footbridge would take the form of a symmetrical cable-stayed deck supported on the existing abutments and a newly constructed 7 metre high V-shaped concrete pier with a F5 concrete finish.

A steel pylon, “the Mast” approximately 23 metres tall would provide support to the stay cables.

The works included modifications to the existing abutments to accommodate the new steel plate deck and the installation of 20 metre long rotary bored piles to support the concrete pier.

Funded by Knowsley Council, the new bridge provides pedestrian and cyclist facilities which link the communities on either side of the motorway and will be used by more than 400 people each day.

Key Challenges

The demolition and installation of the new footbridge required full weekend closures of the M62 motorway.

The closures were immovable dates of fixed duration which occurred during international football breaks. This requirement was imposed to mitigate the impact on traffic generated by local football clubs, Liverpool and Everton. EWCE ensured by pre-planning and collaborative working with all parties that these targets were achieved.

Another challenge faced by the team was working in the confined area of the central reservation to construct the pile cap and bespoke V shaped concrete pier.

Slew locks were fitted to heavy plant & machinery. Varioguard barriers were installed to confine the work area from being entered by motorway traffic and vice versa.

Added Value

Due to the design specification of the Mast, the main components were only available from Japan. EWCE proposed an alternative bespoke Mast built from weathering steel that could be made in the UK. This eliminated the significant programme risk associated with procuring large steel sections from Japan.

The replacement Greystone Footbridge was successfully completed on budget and officially opened by the mayor in November 2015. Since the project has received a highly recommended award at the ICE NW Civil Engineering Awards held in March 2016, the only scheme to receive special recognition from the 20 shortlisted.

Client Feedback

“I am delighted that the new footbridge is now open. This project is a significant investment into the boroughs infrastructure and the new bridge truly is an impressive, eye catching structure. I’d like to thank everyone who has worked on this project and also thank local residents and motorists for their understanding and patience while the work was carried out.”
