Submit new inquiry for this project

(RECESSED): Caltrans only has a specification & detail for recessing crosswalks & limit lines only and does not have a detail or specification for recessing legends & symbols. Are the legends & symbols also being recessed or just the limit lines and crosswalk bars? If the Legends & symbols are also being recessed can Caltrans please provide a detail on how to perform that work? As there is no viable equipment on the market to recess word legends or arrow symbols or bike symbols. Also if the word legends or arrow symbols or bike symbols are not being recessed will Caltrans please consider adding an additional line item for NON-RECESSED EWNV MARKINGS?
