THE A470 TRUNK ROAD (LLANRWST, CONWY) (TEMPORARY PROHIBITION OF VEHICLES, CYCLISTS AND PEDESTRIANS) ORDER 202-

THE WELSH MINISTERS propose, in not less than 7 days from the date of this Notice,
to make an Order under section 14 of the Road Traffic Regulation Act 1984 which is
necessary whilst testing exercises are carried out to the flood defence barrier on the
A470 trunk road at Llanrwst, in the County Borough of Conwy and as a contingency
because of the likelihood of danger to the public during potential periods of flooding.
The effect of the proposed Order will be to temporarily:
i) prohibit all vehicles from proceeding on the length of the trunk road specified in
Schedule 1 to this Notice. The alternative routes are at Schedule 2 to this Notice;
ii) prohibit the riding of pedal cycles on the length of the trunk road specified in
Schedule 1 to this Notice. The alternative routes are at Schedule 2 to this Notice; and
iii) prohibit pedestrians from proceeding on the length of the trunk road specified in
Schedule 1 to this Notice. The alternative routes are at Schedule 2 to this Notice.
The Order, which will operate intermittently, is expected to come into force on 31
October 2025. No more than 3 testing exercises are anticipated during an 18-month
period and would be undertaken between the hours of 05:00 and 08:00. Advance
information signs will be erected approximately 10 days prior to each testing exercise.
Although the proposed Order is only expected to operate as specified above, it will
remain valid for a maximum period of 18 months as a contingency should further
testing be required or in the case of potential flooding circumstances.
