yes, streets can totally change names basically anywhere (even without intersections)! it's not the case here, though. NW 186th St becomes NW 188th St at the corner of NW 54 Ct. easiest way to confirm this is checking the address dataset from Miami-Dade County: http://gis-mdc.opendata.arcgis.com/datasets/address?geometry=-80.294%2C25.944%2C-80.285%2C25.945 (in the public domain -> ODbL compatible)
