Last September, 16-year-old Renee Thompson was struck and killed by a turning truck driver at the intersection of Third Avenue and 60th Street. Now, the crowded intersection has painted curb extensions on two of the intersection’s four corners that shorten crossing distances and tighten turns.

A DOT proposal in January to Community Board 8 had them on the west side of the intersection, but the curb extensions were striped on the northwest and southeast corners of the intersection last week. Pedestrians could use the extra space: Sidewalks in the area are narrowed by subway entrances, tree pits, and enclosed sidewalk cafes.

Two blocks to the east, the neighborhood received another improvement with the final touches on the two-way bike path on First Avenue beneath the Queensboro Bridge. The concrete barrier separating cyclists from pedestrians was painted last month in a pattern mirroring the tiling on the bridge’s archways above.
