Temporary traffic lights and an overnight closure will be in place so survey work on drainage under busy Sidmouth roads can take place from Monday, September 6.
The scheme – running from the town centre up to and along the A375 – will pave the way for a major resurfacing project it is hoped can happen early next year.
Devon County Council (DCC) will be inspecting the condition of pipes using specialist CCTV cameras over the next fortnight.
This will begin in Sidford Road from Monday, September 6, to Wednesday, September 8.
Work will then move to Temple Street, Vicarage Road, High Street and Fore Street from Thursday, September 9, to Friday, September 17.
DCC says temporary traffic lights will be in place while the majority of the scheme is carried out during the daytime from 6am to 7:30am and then 9:30am to 3:30pm.
There will be an overnight closure in Fore Street from 7pm on Sunday, September 12, until 6am on Monday, September 13.
And night-time work in High Street and Fore Street on the evenings of Monday, September 13, and Tuesday September 14, will see temporary traffic lights put in place from 7pm to 6am.
The survey project is being undertaken ahead of a proposed major resurfacing scheme on the A375 in Sidmouth, from Temple Gardens to The Esplanade, being planned for early next year.
Sidmouth representative Councillor Stuart Hughes, who is DCC cabinet member for highway management, said: “With such a major reconstruction taking place next year, it’s important that we carry out surveys of the drainage pipes so that we can plan ahead and any replacements required can be carried out as part of the scheme, enabling the work to be carried out as quickly and as smoothly as possible.”
Contractor Exjet will be carrying out the work on behalf of DCC.
