There's been an interesting exchange on Twitter about the proposed 20mph speed limit in Formby. A closer examination of these and the references shows that the original scheme in the Piecefield Road area is to be extended.

Here's an extract from the  Twitter conversation:

All roads in Formby except Liv Rd, Altcar Rd, Church Rd and Southport Rd to be made 20mph - good for safety and the environment

@LabourInFormby At the Formby Area Committee on the 10 January ALL SiX Ward Cllrs voted through their support of the 20mph speed limit

Then a member of the public asked:

@cllrninakillen @formbyvillageWhat about those living on the roads not included ? These are the roads with speeding lorries and buses !

Another person commented on the accuracy of the claimed environmental impact;

@cllrninakillen @formbyvillage . 20mph good for the environment ?.Highway Agency state a 20mph speed increases Co2 emissions by 20% ?

For those of you who want to clarify the new proposals, here's the map from a report due before Sefton Central Area Committee which meets on 6 June at Maghull Town Hall.
