Transport for London’s director of roads outlines some of the road improvement work planned for the capital over the next 10 years.
- Logistical challenges of improving London’s roads
- The importance of early contractor involvement
- Major upcoming investment in roads
Transport for London’s road network, the red routes in London, covers 5 per cent of the capital’s roads but carries more than 30 per cent of London’s traffic.
As such, it requires constant maintenance and inspection to ensure that it remains suitable to keep all road users in London moving.
Logistical challenges of improving London’s roads
Delivering these improvements, while also ensuring that drivers, cyclists and pedestrians, as well as local residents and businesses, aren’t unnecessarily disrupted is a huge challenge and one that requires expert planning, extensive collaboration and an openness to innovation.
As part of our ongoing maintenance programme, from this autumn we will be replacing or refurbishing a range of structures and tunnels as part of the £200m Structures and Tunnels Investment Portfolio.
“Using early contractor involvement on these major upgrades enables us to achieve best value for money”
This portfolio will include a range of structures, including replacement of four road-over-rail bridges, refurbishing the Grade II-listed Chiswick Bridge and upgrading safety systems and components within the Fore Street Tunnel on the A12.
The second phase of strengthening of the Hammersmith Flyover will also be carried out, building on the first phase of repairs successfully delivered in 2012 to extend the life of the structure for many years.
The importance of early contractor involvement
The four main contractors for these works, Hochtief, Bam Nuttall, Costain and Skanska, have all been procured under an Early Contractor Involvement Framework contract.
Using early contractor involvement on these major upgrades enables us to achieve best value for money, and helps to remove risks that are sometimes not considered early enough in traditional delivery models.
This method ensures we complete works efficiently, collaboratively and with minimum disruption to London’s road users, and is the model we favour for future major investment.
“During the next 10 years, TfL will be investing around £3.8bn into the capital’s road network”
Work on the Hammersmith Flyover will begin in autumn 2013 and will see the remaining 11 of 16 spans strengthened, the bearings replaced and the entire structure waterproofed and resurfaced.
In part attributable to the benefits of ECI engagement, all activities that affect the carriageway both over and under the flyover will be scheduled to occur at night time to limit disruption to users of the flyover.
Major upcoming investment in roads
The portfolio also forms one of the six key strands of investment that will deliver vital road improvements and implement the recommendations of the mayor’s Roads Task Force.
During the next 10 years, TfL will be investing around £3.8bn into the capital’s road network.
Working with partners, including London’s boroughs and the representatives of all road users, we will build on the improvements seen in the management of London’s roads, streets and public spaces in recent years to help ensure London remains one of the most attractive, vibrant, accessible and competitive world cities.
