A road closure is in place on the A48 in Blakeney following a two vehicle collision earlier.
Police were called shortly after 12.15pm with a report that a tractor trailer had overturned following a collision with another vehicle near to Norfolk Lodge on Newnham Road.
While vehicles have been recovered and debris has been cleared, the road will remain closed for a number of hours so that repair work to the barrier can be carried out.
Motorists are advised to find alternative routes.
