BARRIER ELEMENTS: SOLID BARRIERS

TRAFFIC CONTROL BARRICADES Typical Dimensions: Varies by barrier type. Estimated Cost: $45 / unit. May be available via donation/borrowing. Overview: A commonly-used traffic control barrier, these barriers can be used for temporary street closures or to post temporary signs.

Top: Traffic Control Barricades demarcate the start of an activated alley demonstration project in San Jose, CA (Street Plans). Left: NYCDOT uses recycled granite blocks to define a linear plaza / expanded sidewalk (NYC DOT). The blocks also double as seating (see page 34 for more info).

Above: Since spring of 2010, the New York City Department of Transportation (NYC DOT) has partnered with the Mayor’s Community Affairs Unit and New York Cares to create temporary murals on concrete jersey barriers around the City. NYCDOT solicits artists for the program through an RFP process. Selected artists are assigned a site, and are responsible for producing stencils, translating the design for installation and overseeing painting. Barriers are primed in advance, and NY Cares volunteers assist selected artists with mural installation. (Source: 2016 Barrier Beautification RFP; Photos by NYCDOT).
