A10 Wadesmill bypass


Contractors have started repairs on the lime-stabilised section of the A10 Wadesmill bypass in Hertfordshire, which heaved earlier in the year (NCE 1 April). The Highways Agency says four months of testing and analysis has determined small ridges and cracking resulted from 'a chemical reaction within the road foundation layers' - but declined to comment further on the cause.

Remedial work will involve full depth replacement of affected sections.
