17/08/1998 One of the road blocks constructed by Northamptonshire County Council by mid-July 1940, on behalf of the Central Midland Command. It was constructed on a site approved by the CRE Warwickshire District. The carriageway was not permanently blocked but steel stanchions and/or sand bags and lump stone were provided in order to close the road quickly in the event of an emergency.
For further information see SRF. Additional notes on Location: The contemporary schedule gives the Location as N of the junction with Mill Lane and Doddington Road on what was the A45 (this part is now A509). In fact , these two roads did not meet the A45 in one place but intersected in two completely different Locations.
Doddington Road met London Road just below the town centre and Mill Lane emerged further S near the Borough boundary. The latter seems the most likely site for a roadblock of this period and this is reflected in the Grid reference given - Dr. S. R. Hollowell.
