This error would have been tripped because this way goes under the bridge at Deerfoot Trail, ~700 m south of this point.

In reality this isn't open to motor vehicles anyway, so I've changed it to a foot/cycle path. The clearance under the bridge is... I'm not even sure, but at least a good 6-8 m, it's huge: no one it going to bonk their head riding their bike under it anyway.
