McClintock Drive, Tempe. The left buffering necessitates a “criss cross” maneuver.
McClintock Drive resurfacing project, city of Tempe, AZ completed July 2015 — added left buffered Bike Lanes (LBBL) between Guadalupe and Broadway Roads, which incidentally crosses a major freeway interchange, US60. This treatment approaching a RTO lane requires thru-going bicyclists and right turning motorists to criss-cross.
Like other arterial roads in Tempe, this road is very wide with a high speed limit (45mph throughout, I think)
The old configuration was sometimes 3 thru lanes in each direction, and other times 3X2; and formerly no BLs in this area. The volume on this arterial (like others in Tempe) has dropped markedly since the freeways have been completed and widened (SR101, and US60).
The road is sometimes exceedingly wide — at the intersection with Baseline Rd, there is now: two thru lanes in each direction, a double left turn only lane, a BL and buffer space in each direction, and a RTO lane. Phew.
From what I’ve gathered, the street engineers in Tempe are under some sort of speed illusion — claiming high speeds “helps traffic flow”; which is odd since above some speed (40mph?) road capacity decreases (because drivers will allow more distance between vehicles), and anyway, capacity is constrained by signalized intersections. The 35mph “at all times” speed limit adjacent to all schools along arterials was instituted years ago, and as things turn out, traffic has not gridlocked.
