Key aims and challenges
The project involved the reconstruction of the southbound off-slip of the Hailey Interchange on the busy A10 dual carriageway outside Hoddesdon, Herts.
The existing carriageway was excavated before the original drainage was replaced and new, additional drainage constructed. The carriageway was reconstructed, including geogrid and geotextile layers, before being asphalt surfaced. Road markings, anti-skid surfacing and vehicle restraint barriers were also installed.
The slipway was closed for the duration of the works and a diversion put in place. One carriageway of the adjacent section of the A10 was closed for two short periods to enable the works to progress safely.
How did we do?
The project was completed on time and on budget, thanks in part to extended working hours and weekend working.
Cost and environmental benefits were achieved by recycling material on site. Approximately 70% of the existing concrete sub base was crushed to form the capping layer for the new highway construction.
