Cheshire County Council's Design Aid states that carriageway construction shall be designed in accordance with the principles laid down in the Highway Agency Standards; Design Manual for Road and Bridges Volumes 1 to 10.
Cheshire County Council's Design Aid has been adopted as policy and is a statement of the adoption standards of the Highway Authority. It also states that any adverse impacts are addressed and the Design Aid is to be used in the assessment of planning applications. Unless of course you are Cheshire County Council then you can throw it out of the window along with planning consent and implement any old bodge you want.
Cheshire County Council's Design Aid also states that there is a need for certain minimum standards which will ensure that road safety is not compromised and that roads and footpaths are fit for there intended purpose. In addition it also states that safety of all road users remains of paramount importance and is a key issue which must be addressed at the design stage. Until of course you are Cheshire County Council and you need to extricate yourself from your self created difficulties then you can throw safety out of the window along with the design aid.
