In the next two months, drivers and cyclists citywide may encounter some blocks closed off for a couple of days due to surface treatment work, and the blocks may appear chocolate brown-colored for the following four to five weeks. It's part of the Department of Public Works' latest road micro-surfacing effort, a process that involves applying a crushed-rock and liquid-oil mixture that protects asphalt pavement from inclement weather, sun wear and natural aging.
The work started Wednesday on 38th Avenue and 46th Avenue between Fulton and Cabrillo streets. It will include 400 total streets that were chosen for being in residential areas and having a "good"  Pavement Condition Index score of 64 to 84, on a scale of 0 to 100.
