THE main road through Westward Ho! which was closed to traffic on Tuesday could remain shut for up to eight weeks.
Highway officers closed Atlantic Way at around 4pm on Tuesday due to fear that a gabion wall related to a nearby development could collapse.
Emergency measures are being taken to repair the wall and Devon County Council have said it could remin shut for up to eight weeks.
Councillor Stuart Hughes, Devon County Council cabinet member for highway management and flood prevention, said: "In the interest of public safety, Devon County Council has had to undertake an emergency closure on the B3236, Atlantic Way, adjacent to the Linden homes site.
"The gabion wall retaining the bank is starting to bulge and there is a possibility that the bank could slip further.
"Devon County council is awaiting proposals from the developers on how it is going to rectify the problem and our structures team will ensure any work is appropriate for the site and fit for purpose.
"This section of the road could be closed for around 8 weeks and a diversion is currently in place."
The closure comes at the same time as Nelson Road in Westward Ho! has been shut for emergency sewerage works.
It is expected to remain shut for at least another two weeks.
Diversions are in the place in the area, with the diversion for Atlantic Way being via Lakenham Hill, Northam Square, Sandymere Road, Golf Links Road and Beach Road.
