On the 1st December 2010 the new dual carriageway was
opened to reduce congestion, improve journey times and safety
between the M1 and Bedford. The new eight-mile route
- which links junction 13 of the M1 to the Bedford
southern bypass- replaces the former A421 single
carriageway. Environmental work started on site in
October 2008, with major construction starting in April 2009
and completion in December 2010 - one month ahead of schedule.
Up to 27,000 vehicles per day use the A421, and high traffic
flows on the original A421made journey times unreliable and
resulted in a poor accident record. The new dual carriageway is
hoped to bring significant improvements. The former A421 will be
de-trunked and become the responsibility of Bedford Borough and
Central Bedfordshire Councils.
