 In December 2009 a Stanground Bypass (mostly dual carriageway) was opened on the eastern approaches to Peterborough.This actually lengthens the route of the A605, although those using the A605 and Peterborough Bypass towards Whittlesey will find it shorter.When the Lilford roundabout to Barnwell turn section was improved in the 1990s an original milestone was uncovered and reinstated on the northeast side of the roundabout.
