Previous post on this subject:
On the 28th December 2013 I asked Central Bedfordshire Council:
As part of this new scheme you are showing a dedicated left hand only lane on the A1 North which shows A6001(W) and an additional arm has been added to the “longabout”.As far as I am aware there is no A6001(W), where is all the traffic in the left hand only lane going to go??"
CBC denied any responsibility for the scheme despite their contact details being included for comments.
Having pursued this I have today received an interesting statement from the Senior Project Manager for the contractor, EC Harris (UK) Limited:
I am the Project
Manager for this project on behalf of Central Bedfordshire Council and apologise
for the delay in responding (I have only today seen sight of your email). This
stub road is a farm access only and will have signing and a gate to prevent
unauthorised access. It also provides a facility for any future expansion to the
west should this be required. A full explanation is given
below.
The proposed
highway improvements to the A1 roundabout junction with the A6001 London Road,
south if Biggleswade, provide significant capacity improvement to the existing
junction in order to minimise impacts from traffic flow increases generated from
development within Biggleswade, currently benefitting from having planning
consent.
Increased traffic
movements at the junction will occur over future years to reflect build out of
consented development within Biggleswade and from general traffic flow increases
along the A1 corridor. The improved roundabout junction is being provided to
reflect this demand and has been fully considered by both the Highways Agency
and Central Bedfordshire Council (in their capacity as local highway authority)
as the most appropriate and indeed preferred form of junction and junction
improvement at this location.
Inclusion within
the proposed scheme of a new “west” arm to the junction has been provided for
future proofing purposes such that if future development to the west of the A1
was deemed appropriate, it could be delivered without recourse to further
reconstruction works of the new roundabout presently being
procured.
Provision of this
west access stub is accompanied by the provision of gates across the stub on
completion, permitting access to residents at Beaufort Farm only at this
time.
The roadmarking
scheme detailed on the construction drawings shows the final scheme which
includes future development gaining access from the roundabout via the west
stub.
An interim
roadmarkings scheme will be implemented until such time that the west access is
required for development traffic, this scheme providing two straight ahead lanes
and a right turn lane for northbound A1 traffic approaching the roundabout.
Access to the west stub will be from the northbound nearside lane as on any
roundabout.
The existing
southbound left turn lane from the A6001 onto the southbound A1 carriageway is
being significantly improved as part of the highway improvement works and is in
full accordance with the Design Manual for Roads and Bridgeworks in terms of
complying with geometric layout criteria.
Additional to the
highway works at the roundabout, the A6001 London Road is to incur a reduction
in the speed limit between Pegasus Drive and the A1 roundabout from 70mph to
40mph both during the construction period and thereafter. This will
significantly reduce the approach speeds of traffic on the A6001 London Road
heading south towards the A1 roundabout and via the improved left turn lane onto
the A1 southbound.
The Highways Agency
is programming to commence highway improvements on the strategic road network
this year which will improve capacity within the region along the A1. The
Highways Agency is ultimately responsible for the safe and efficient operation
of the trunk road network and is charged with implementing regional capital
spend budgets for this purpose.
The Biggleswade
Roundabout Improvement scheme is being jointly funded by developers and the
Council to reflect identified highway capacity improvements necessary to
accommodate recently (and future) consented development traffic. It is not the
obligation on the Council or developers to fund the ongoing improvement of the
trunk road network to accommodate general traffic growth across the network,
this being the responsibility of the Highways Agency.
I hope that the
above responds adequately to the point you raise.
