After joining the slip road from the M61 the directions I were given were to keep right to the roundabout and then take the 1st exit off the roundabout. As you can see there is a feeder lane from the M61 slip road onto the M65 slip road so the roundabout is clearly not the best option. I don't recall this ever happening before so I can only presume it's related to the arc tweezing stuff that was committed recently. I used mkgmap r1280 and the following command line to produce the map java -Xmx2048M -Dlog.config=$abspath/logging.properties -jar mkgmap.jar --adjust-turn-headings --remove-short-arcs --drive-on-left --check-roundabouts --add-pois-to-areas --latin1 --gmapsupp --route --style-file=$stylefiles --max-jobs --code-page=1252 --country-name="Great Britain" --country-abbr=GB --tdbfile --tdb-v4 --description="Map of GB" --family-name="Great Britain" 700000??.osm $contourdir/uk/*.osm >> debug.txt 2>&1 Cheers Paul
