Miami-Dade County upgraded the road guide signs in the vicinity of the existing 23 Metrorail stations. WGI developed aerial base maps of the roadway systems leading to each station, including existing and proposed signage, and provided a report with appendices and recommendations for signage upgrades. WGI also developed the design criteria package for typical guide signs installed at the roadways and expressway to direct motorists and pedestrians to each Metrorail station.
