C332 BRIDGE STREET CHATTERIS
C332 HIGH STREET CHATTERIS
C332 MARKET HILL CHATTERIS
This implies that the route continues south along the High Street to Market Hill, and then meets the B1050 at Park Street; however, this situation doesn't appear to be reflected in any maps, which show the road ending on the High Street junction with the B1098. The same road list also lists the C333 and C334 as having replaced Class II roads in the centre of Chatteris - however, looking at more recent road lists and signs on the ground, this does not appear to be the case on the ground.
