DOT contractors are putting down new bike lane markings on Park Slope's Fifth Avenue this afternoon. In addition to refurbishing the original bike lane laid down in 2004 and the sharrows installed in 2006, the crews are adding reinforcements, like the chevron markings through the intersections pictured below.
It would be entirely fitting if these improvements were DOT's response to the recent complaints from a small number of merchants and the idiotic editorial that ran in the Brooklyn Paper claiming that these pavement markings -- and the cyclists who use them -- are somehow interfering with deliveries and parking on the avenue. But this is probably just regularly scheduled maintenance. Winter snow plows really do a number on these bike lanes.
