The existing cycleway on Huntington Road was simply a painted demarcation on the road. This needed upgrading to physically separate the cycleway from the main carriageway, whilst still allowing for a car or bicycle to easily mount or dismount the kerb and safely regain control.
The proposed new cycleway would run for 1.5km in one direction along Huntingdon Road. The Council chose a hybrid cycleway design, which would be raised above the existing carriageway using single kerb segregation. However, early consultations with the public and cycling bodies highlighted that a standard kerb could pose a safety hazard to cyclists joining the cycleway at an acute angle. In order to address this problem, a bespoke kerb was required.
The Cycling Infrastructure Team at Cambridgeshire County Council worked with main contractors Skanska to design a new concept in cycleway kerbing for use as a divider between the carriageway and cycleway
Once the initial design was drafted, Skanska contacted Charcon, the commercial hard landscaping division at Aggregate Industries, to determine if it was a product they could manufacture.
Skanska then worked alongside Charcon’s technical team to propose a bespoke ‘Cambridge’ Kerb to the County Council, and an initial order for 1,100 kerbs was placed.
At the start of the manufacturing process, Charcon invited both Skanska and Cambridgeshire County Council to take part in a site tour at the company’s manufacturing plant in Hulland Ward, Derbyshire. During the tour, the team was able to view Cambridge Kerb in production and witness the finished results straight from the production line.
The first load of kerbs was delivered to site on 7th January 2015 with the project due for completion in the autumn of 2015.
Grant Weller, Product Manager for the Cycling Infrastructure Team at Cambridgeshire County Council comments: “Cambridge is experiencing major economic growth and expansion. The Huntington Road cycleway scheme was identified as part of the transport strategy, which aims to address the city’s traffic capacity issues by promoting more sustainable modes of transport.
“The chosen option of cycle lane, a hybrid cycleway, is raised above the existing carriageway using single kerb segregation. The kerb we designed, named Cambridge Kerb, has the depth of a full height bullnosed kerb required to withstand vehicle overrun but has a 12.5 degree horizontal profile, creating a gentle and smooth transition between the carriageway and the new cycle lane. Charcon were approached with the design and has now developed the proposal into a reality.
“With the growth of cycleway infrastructure throughout the country the potential of the new Cambridge Kerb is huge with a number of other Local Authorities already showing an interest. My thanks goes to the team at Charcon who took our initial design and created this purpose built kerb.”
