Over the last few months on my many rides thru Sunnyside I've been watching as NYC DOT has been upgrading at least a 1/2 dozen of the "mixing zones" at busy intersections with concrete on Skillman and 43rd Ave. It really makes a HUGE safety and comfort difference.

Sean Quinn, NYC DOT's Associate Deputy Commissioner of Office of Livable Streets, gave us an exclusive about recent places systemwide where the department has been adding concrete to better protected bike lanes.
