MOTORISTS are being warned to expect delays on three major roads which connect the district to North Devon.
A seven-mile stretch of the A377, which is the main route from Crediton to Barnstaple, will be closed until at least October 29 to allow roadworks to be carried-out.
Devon County Council said a 26-mile diversion, which will divert traffic via South Molton following a closure between Umberleigh and Kingford Bridge, was "necessary" to allow workers to build a new retaining wall and repair an embankment damaged by flooding.
Pat Leach, who commutes from Crediton to Barnstaple every day, said: "I understand the A377 needs to be closed for roadworks, but it's such a busy road and the detours take you miles out of your way.
"I would have thought in this day and age they could find a way to keep it open during the day – even if it's single-file traffic over a temporary bridge – and work on it at night.
"It's shut for such a long time that it's going to cost me pounds in extra fuel. But I don't think the council particularly cares about poor commuters."
Motorists will be diverted via Kings Nympton, George Nympton, South Molton, Barnstaple Road, the road from Filleigh Bridge to Aller Cross, the road from Stags Head to Kingsland Barton, Nadder Lane, Umberleigh and vice-versa.
A section of the North Devon Link Road was closed yesterday (September 16) and will be shut for 10 nights for resurfacing and bridge repairs to be carried out.
The A361 will be closed from 8pm to 6am, from Mondays to Fridays from Bolham Roundabout, Tiverton to Bish Mill, South Molton.
At the same time, bridge maintenance teams will be carrying out repairs to Exe Bridge, Sturcombe Viaduct and Ash Mill Viaduct.
All other bridges on route will have routine maintenance, gully cleaning, surface patching and resurfacing.
Devon County Council cabinet member with responsibility for highway maintenance, Councillor Stuart Hughes said: "It makes sense for these various teams to work together to complete this important piece of work within one time span.
"While we appreciate, this may cause some disruption to road users, we have tried to optimise the resources we have to enable the work to be done as quickly as possible."
In addition to this, work is to be carried out just west of Tiverton on the B3137 at Cruwys Morchard for nine weeks to stabilise the embankments supporting the carriageway.
This will mean daytime closures from 8.30am until 5pm with temporary traffic lights being used outside of these times.
Meanwhile, the B3137, which connects Tiverton to Chawleigh, Witheridge and Chulmleigh, and will be closed at Cruwys Morchard Hill until November 15 because of major works to repair part of the road which has subsided.
Work has now been completed ahead of schedule on highway drainage measures at Padbrook Hill on the Cullompton to Bradninch road.
