哥伦比亚街自行车道是布鲁克林林荫道的第一个完成的部分，允许与bikeway人行道前所未有的共享，同时敏感地结合公共艺术。
自行车和街景设计为两个速度：行人和骑自行车。步行者通过零售和住宅区沿着带有连续鹅卵石带的绿树成荫的人行道散步。这种可渗透的树木区域使用结构土壤促进树木的健康和雨水渗入。 MNLA与艺术家Nobuho长泽的合作提供在青石路面的雕刻树剪影的地方。配合时代，这项工作是一个固定的变化标志，激励行人考虑自己的存在随着时间的推移。自行车设计随着自行车更快的节奏移动。大图案的彩色花岗岩带与街道树结合，以标志沿着bikeway的速度。

The Columbia Street Bikeway is the first completed section of the Brooklyn Greenway that permits the unprecedented sharing of sidewalk with bikeway while sensitively incorporating public art.

The bikeway and streetscape are designed for two speeds: the pedestrian and the cyclist. The pedestrian strolls through retail and residential areas along tree-lined sidewalks with continuous cobble bands. This permeable tree zone uses structural soil to promote tree health and stormwater infiltration. MNLA’s collaboration with artist Nobuho Nagasawa affords places for carved tree silhouettes in bluestone pavement. Dubbed Timecast, the work is a fixed marker of change that inspires pedestrians to consider their own presence over time. The bikeway design moves with the faster rhythm of the bicycle. Large patterns of colored granite bands combine with street trees to mark speed along the bikeway.
