<div dir="ltr"><div><div><div>Hi Adam<br><br></div>I think option 1 is the consensus way to map these, certainly so in the West Midlands. Option 3 is more verbose but not incorrect.

My worry with Option 3 is that some routing programs might view it as two (or even three) separate sets of traffic lights.<br><br>Any advice gratefully received,</div><div><br></div><div>Adam<br></div></div>
